Ditching Your Run-Flat Tires for Non-Run-Flat Tires on Your BMW? Read This First!

Michelin Pilot Sport PS2 ZPMany BMW owners are opting to replace their factory run-flat tires with conventional non-run-flat tires. One can literally find hundreds of posts across popular BMW forums filled with disapproval of the Original Equipment run-flat tires. Many customers have complained that the tire is either too stiff, gets too many bubbles or wears out too quickly. 

While it seems that some drivers are happy with their switch to non-run-flat tires, not everyone is in the majority. Be sure to study the trade-offs, as well as some of the alternatives you may not have considered.

  • Since many have tested only one or two models of run-flat tires and assume all run-flats have the same problems, it's important to remember not all run-flat tires are created equal. Did you know there are newer generations of run-flat tires available today that eclipse the older technology? One shining example is the Michelin Pilot Sport PS2 ZP which is praised in forums as an improvement over older run-flat models in regards to ride comfort, wet and dry grip, as well as treadwear. Another example is the Bridgestone Potenza RE960AS Pole Position RFT, which is an outstanding all-season run-flat tire. 
     
  • Run-flat tires do not wear out faster. Comparing the Michelin Pilot Sport PS2 against the Michelin Pilot Sport PS2 ZP (run-flat model), both tires have the same rubber compound, same dry and wet grip and same treadwear. The PS2 ZP is an outstanding run-flat tire. Take a look at this review of the tire from a 2007 BMW 335i owner:
"Took the car out for a long drive, mostly back roads and some interstate to take advantage of our 80 degree day. This tire will take all of your preconceived notions regarding the harshness and ride of RFT and throw them out the window. I still cannot get over how smooth the ride is. This car now rides smoother than it did with non-run-flat all-seasons that just came off. Also, this is one very quiet tire.

As far as the handling, sticks like glue! The steering response and on-center feel is exceptional. While I think the Bridgestones had a slightly (very slightly) quicker turn-in, the PS2 ZP does not have the 'nervousness' that was associated with the Bridgestone that required those constant steering inputs. Bottom line, for those of you like me who did not prefer the original Bridgestones, but still want RFT capability for whatever reason, your prayers have been answered by Michelin." -- Tire Rack Consumer Review, 2007 BMW 335i

I have an X5 with 20 inch wheels and run flat tires. This is the worst ride I have had in a BMW in my life. I also have an E46 330ci with a lowered sports suspension and even this car is softer than the X5. This is about the stupidist thing I have seen BMW do - putting an SUV on 20 inch sports wheels. Don't buy them, simpl,as that. Make it a condition when you purchase: swap the tires or no deal.

Don't be stupid, learn from my experience, these things are really bad.

I drive a 2007 BMW 328i. I ditched the runflats, and I will never look back! Bought Contintental Extreme Contact DWS. A smooth, controlled, QUIET ride. Love the handling and control. Get 5 mpg more on the highway and 3 mpg more in the city. Bought the Conti Comfort Kit and AAA for back up. Now my car feels and drives like a German-engineered performance vehicle. Give up the runflats! You won't regret it.
Tuesday, January 24, 2012 by Armand

My runflats developed cupping at 15000 miles on my 2009 X5. The road noise was unbearable. Made a deal with the dealer to replace the runflats with MX4s...runs like a real BMW now. Looking for a new car and would like to get another BMW (my 6th) but I will not buy unless I can get non runflats..period!

Please recommend alternate run flat and nokn-run flat tires for my 2008 BMW 528i Sport model currently fit with OEM Dunlaps.
Friday, February 17, 2012 by Gary

Chris,

There are quite a few tires in both run flat and non runflat tires that are made in size 245/40R18 that might be appropriate based on your driving style, conditions, priorities in what is important to you, etc. For a proper recommendation based on the above, please feel free to shoot us an email or contact one of our sales specialists for assistance.

Like others, I am having a long-time battle with the run-flat Dunlops on my 2008 BMW 535xi w/ sport pkg + 18" wheels. The dealer has balanced them numerous time to no avail. They claim cupping is causing the harshness, vibration and noise. This started with less than 14,000 miles on the vehicle. I previously had an encounter with a pothole (at 6500 mlles) which necessitated replacing the right front tire. Later, the dealer said there was a slight bend in the front and rear rims and had them straightened. Still no improvement after more balancing. I avoid using the car as it is so unpleasant to drive. Can you suggest some remedies? I live in Florida but may occasionally travel to snowy areas. I am hearing that non-runflats may be the best option. Help !
Wednesday, March 14, 2012 by Gary

John,

While a non run flat tire will not necessarily be more resistant to potholes, you can find all-season tires in a non run-flat for your car that will improve the ride and have longer tread wear. Check out the Bridgestone Potenza RE970A/S as a great choice for what you're looking for.

5BMW 5 GT (2010)supplied with Continental run flat tyres, no option available when car purchased Great car genuine GT, totally inadequate tyres for country driving. Hard ride, to canvas at 30,000 kms. Impossible to replace in the country. Shame on BMW great car, rotten expensive tyres.
Saturday, March 17, 2012 by Pete

Hello,

As of today, I have now replaced a total of EIGHT Bridgestone Potenza RE050A run flat tires (Front: 245/40R19 94W; Rear: 275/35R19 96W)
that came with my 2009 BMW 650i. This is within 65,000 miles of mostly highway driving in New Jersey. I love the car, but with repair not an option and a replacement cost of $550 each, I am considering switching to non-run flats. Can you recommend a make and model for me? I do not drive aggressively - just use the car for my daily commute to and from work which is about 40 miles of highway driving each way. Priorities for me are just a good safe ride with good durability.

Also, what issues will I face with installing these non-RFTs regarding the electronics/diagnostics which have some sort of sensor built in to detect problems with the run flats? Can I have my local mechanic install these or would I be better suited going to the BMW dealer to install (and will they install non-RFTs at all)?

Sorry for the barrage of questions. Just a frustrated consumer. Thanks in advance for any advice you can offer.
Monday, March 19, 2012 by Gary

For a smoother, quieter ride and longer wear you may want to consider an all-season tire like the Michelin Sport A/S plus.

Fortunately the vehicle has no way of knowing whether or not run flat tires are on the car, so there are no problems with vehicle electronics by using on run flat tires.

Most modern tire shops should be able to handle the changeover with no problem.
Tuesday, March 27, 2012 by Lynn

I have a 2009 128i with less than 10K miles on it. I'm nearing lease end, and the dealer is telling me that I must replace all of my run flats due to wear. This is ridiculous on a car with less than 10K miles, and I don't want to have to do this again in another 10K miles, so I'm seriously considering a switch to non-run-flats. My only hesitation is that if I did this, I'd want a spare, and not a full-sized one, as it would eat up all the trunk space. Has anyone been able to find one of those smaller, "donut" spares for a BMW that allow you to get to at least drive to the nearest tire store when you get a flat?
Tuesday, March 27, 2012 by Gary

Many dealers require the vehicle to be returned with run flat tires, so you may want to confirm you can turn in your car without them. I'm not familiar with any temp spare setups for this car, sorry.
Tuesday, April 3, 2012 by Alexo

@ Gary. Yes, BMW does have a "donut" space saver spare wheel kit. While I live in Australia, I've seen the kit in dealers here and it should be available if you hunt around. Maybe via internet if BMW USA doesn't have it. Incidentally I'm just about to replace my original Bridgestone RF tires on my 2009 330d after putting 30k kilometres on them - so either you drive like Michael Schumacher or there is a mechanical problem such as misaligned wheels or chassis or really bad tire pressures.
Thursday, April 19, 2012 by Bill

My 2008 335i coupe came with Bridgestone Potenza run flats (225/40 R18 front, 255/35 R18 back). I am about to change them out for the second time in four years. Is there a non-run flat tire anyone would recommend for this car? And, will changing affect the electronics/computer at all? Thanks for your help!
Friday, April 20, 2012 by Gary

Changing to a non run flat tire would not affect anything related to the electronics or on board computer. Our top performance non run flat tire in these sizes is the Michelin Pilot Super Sport.
Sunday, April 22, 2012 by Xyna

My 2009 BMW 523i came with a Dunlop RFT OEM. It only has 29km mileage yet all the four tires (Front:245/40 R18 & Rear: 275/35 R18) are already worn out and require replacement. The BMW dealership from whom I purchase the car does not have the RFT in stock and so does the other tire dealership in town. Is there any technical risk in replacing the RTF with non-RTF tires? If not, what types of non-RFT will do you commend? Also, do I have to retain the two different set of tires for the Front & Rear?
Monday, April 23, 2012 by kelly

We tried substituting regular tires for the back (instead of run-flats) and it's AWFUL driving on the highway at 70+ mph. Don't do it! I just don't know what to replace the tires with because I hated the BMW OEMs. It was so terrible on the highway, I refuse to do it again. If you've ever been behind a tractor-trailor and been wind-buffetted, that's what it's like, for serveral hundred milles!
Monday, April 23, 2012 by Gary

As long as all four tires match (same brand and model of tires) you can use either run flat or non run flat tires on all four wheels without a problem. Top non runflat tires in your sizes to consider would be the Michelin Pilot Super Sport for a summer tire, and the Bridgestone RE970 A/S for an all season tire.
Tuesday, April 24, 2012 by mike g

I want to buy a bmw 128 and I know it can only be purchased with run flat tires. After reading these comments, I am very unlikely to buy a bmw!!
Wednesday, April 25, 2012 by Gary R.

Mike G, buy the 128. I have the 2009 128 with OEM Bridgestone RFTs. They have 30K miles and perform beautifully. All season, good grip, perfectly smooth and round. Rears are wearing a bit, fronts look like new.
Tuesday, May 1, 2012 by ellen crow

2012 Mini Cooper S if I eventually want to change tires to regular tires, not run flats, do I have to do all 4 tires or can you do two at a time? Can I use the same rims the run flats are on? Will the tire pressure monitor still work? What regular all season tire would you recommend?
Tuesday, May 1, 2012 by Gary

Ellen,

If you're just replacing two tires, it is important to purchase the same brand name and model of tire. Install the new tires on the rear. If replacing all four, you can go to non run flat tires on the same wheels and the monitors will still function properly. For 17" all season tires, check out the Continental DWS or the Kumho ECSTA 4X.
Sunday, May 6, 2012 by Mark

Tirerack has been helping us with our recent purchase. We found that the car is tuned for the stiffness of RFT tires, so we have to put our previous tires back on. We were told to just bring it by the warehouse in Southbend. Looking forward to future reviews.

Best regards,
Mark

Can you recommend replacement of run flats to non rf for 2007 328i, Bridgestone Turanza EL42 * 205/55 R16 91H? I have 65,000 miles and a flat in the rear tire.
Tuesday, May 8, 2012 by Gary

Tim,

If you are replacing all four tires and looking for a good non run flat all-season replacement tires, there are many good choices available. Two that we've had good experience and feedback with are the Michelin Primacy MXV4 and Kumho ECSTA 4X.
Tuesday, May 8, 2012 by Alicia

I have a 2008 BMW X3. I recently had one of my original Pirellis go flat. Trying to decide whether to replace the Pirelli or purchase four new non-run flats (thinking about Michellin Primacy). Other 3 tires are good condition but are the originals and might have to be replaced soon anyway. Advice? (mix of in-city and highway driving 40/60)
Wednesday, May 9, 2012 by Gary

Alicia,

The Michelin Primacy MXV4 is an excellent tire choice if you decide to replace all four. If replacing a single tire, be sure to match to the Pirelli.
Saturday, May 12, 2012 by Gary

I have a 2008 BMW Z4. I need to rear tires. Can I safely put non run flats with 2 very good run flats on the front?
Monday, May 14, 2012 by Gary at Tire Rack

Gary,

It is important to avoid mixing run flat and non run flat tires as this results in unstable handling.
Thursday, May 17, 2012 by Kd

Someone please help! Just purchased an 08 328i vert and experienced the infamous "buffeting" noise at hwy speeds. Dealership contends this is due to slightly bent passenger side rims and RFT's that are splitting and need to be replaced. I desire non-rft's and would love recommendations! Should replacing the tires and smoothing the rims alleviate te noise regardless if I choose non-rft's?? Thank you!
Monday, May 21, 2012 by Peter

My dealer told me that replacing my RFTs with non-RFTs on 2009 335i coupe will definitely affect electronics including tire pressure light and other sensors. Also dealer will not certify car if I go non-RFT, which means no BMW financing available. Any way to solve different opinions on electronics? Thank you.
Monday, May 21, 2012 by Gary

Peter,

While I can't speak for BMW's financing or certification I can tell you with 100% confidence that the TPMS sensors will not be affected by going to non run flat tires. Keep in mind that the TPMS senors simply measure the air pressure inside of the tire, they do not have any way of determining what type of tires you have.
Wednesday, May 23, 2012 by katikaneni

I have a 2007 335i and i am in a situation to replace one tire and 2 more are at bald level of their grip. Can someone suggest good RFT and non RFT tires ? one of the tire was replaced at BMW service center with a conti contact pro sir but merchants say they are the worst tires to have. Please suggest.
Thursday, May 24, 2012 by Clint

I want to replace my Continental run flats 225/50R/17 on my 2008 BMW 528i with non run flats 245/50/17's. I live in Houston lots of rain, very hot summers and no snow. Whats the best tire? Looking for a smoother, quiet ride with good handling. Best bang for my buck?
Thursday, May 24, 2012 by Monica

I have a 2009 328i coupe sport package and I have replaced my tires twice in less than four years. I am so sick of RFT...what non-RFT would you recommend for my car. I need them now...so stressed
Thursday, May 24, 2012 by Gary

katikaneni,

If you're replacing only two tires, it is important to match to the same tire brand and model of tire for safety and stability. If you replace all four, many have been happy with the Pirelli Pzero Nero A/S RFT and Bridgestone RE960 A/S RFT for run flat all season tires. Top non run flat all season tires would include the Michelin Sport A/S plus and Bridgestone RE970 A/S.
Thursday, May 24, 2012 by Gary

Clint,

245/50R17 is not just wider but also taller and it may rub. 245/45R17 would be the same height while being wider and would fit with no problem. For value oriented, smooth and quiet riding summer performance tires, I would suggest considering the Continental Extreme Contact DW.
Thursday, May 24, 2012 by Gary

Monica,

Top non run flat all season choices that I would recommend you consider are the Bridgestone RE970 A/S and the Michelin Pilot Sport A/S Plus.
Thursday, May 24, 2012 by Aaron

My 2010 335i with sport pkg started making terrible road noise at 12k miles. My car looks and runs great, but I am embarrased to take anyone for a ride due to the terrible tire noise. Sounds like I m driving a 4x4 with off-road tires.
Friday, June 1, 2012 by Robert

What tire would you recommend to replace the OEM ContiProContact SSR (225/45R17) on a 2011 BMW 335d? RFT and GFT tire recommendations. I'm looking for a tire that will outperform and provide a better ride than the OEM RFT.
Friday, June 1, 2012 by Gary

Robert,

I would suggest taking a look at the Yokohama Envigor ZPS and Bridgestone RE960 A/S RFT for run flat all season tires. Top non run flat all season tires would include the Michelin Sport A/S plus and Bridgestone RE970 A/S.
Friday, June 1, 2012 by Robert

Gary,

I'm inferring from your reply the P Zero Nero A/S RFT isn't as good as the Envigor ZPS or RE960 A/S RFT.
Tuesday, June 5, 2012 by richard

i have a 2007 BMW 335is and need to purchase new tires. From reading the other questions and responses i do not see any reason not to purchase non RFT as long as you have AAA and are not driving in remote areas. do you agree?
Thursday, June 14, 2012 by Art Chen

Hi Gary,

Finally found your blog on RFT vs non-RFT. I just bought a BMW 535xi wagon (with 18" wheels) and have Goodyear RFT on front and Bridgestone RFT on the back. The ride is very bouncy and noisy. So I was looking to go back to the normal 17" wheel with new non-RFT and thus can get a spare in the trunk.

Then I read your blog. However I need all season tire (had very good experience with Michelin Primary MVX on my 2006 BMW wagon). Looks like you would recommend either 18" Michelin Pilot Sport A/S plus or Continental DWS? Which one would give me a quieter and smoother ride?

How about the Plus ZP version of the Michelin? Would it perform as well as Plus version in term of ride and noise? If so then I can only replace all four tires with the convenience of RFT.

Finally when I looked at 17" wheels for the BMW, your wheels all come with 40mm offset while the BMW OEM wheel comes with a 43mm offset. Does it matter?

Many thanks.

Art Chen
Thursday, June 14, 2012 by Gary

Art,

The Continental DWS to have a softer ride than the Sport A/S Plus. Noise should be similar between the two. The ZP (run flat) version would have the same noise levels with a bit stiffer ride. A wide range of wheel offsets will fit your car with no problem, including the 40mm offset wheels we list on our site.
Wednesday, June 20, 2012 by Jack

I have BMW 335 is 2011 with Pirelli run flat tires. 255/30R19 on rear and 225/35R19 on front. Would you recommend either another run flat or a non run flat tire?
Wednesday, June 20, 2012 by Gary

Jack,

For run flats in these sizes I would go back to the Pirelli. For a non run flat tire, the Michelin Pilot Super Sport is the best available.
Saturday, June 23, 2012 by Mel

Im so upset. I have a 2011535i sadan w/sport package. The Goodyear runflats lasted 11 months. I purchased 4 Bridgestone run flat tires in november 2011 and now in June 2012 i need more. The dealership is saying both of the rear tires are bold after only 9500 miles on them. Is this normal? What be done with this? Also what non run flat would you recommend ?
Monday, June 25, 2012 by Benjamin

I have a 2009 328i and am in need of replacing my front tires. After reading previous posts I understand mixing RFT and non-RFTs is not recommended. What tire do you recommed for my car type?
Monday, June 25, 2012 by Gary

Correct, mixing tires is not recommended due to unstable handling. If you're just replacing two tires, we recommend matching to the same brand name and model of the other two good tires.
Tuesday, July 10, 2012 by Lisa

I have just purchased a 2011 328ix and the dealer is trying to sell me on $1,700 4 yr tire replacement insurance. Wondering if I am better off waiting until I need to replace a tire and then go ahead with replacing all with non run-flat tires. Would really appreciate some guidance. Thx.
Tuesday, July 10, 2012 by Lisa

I have a 2006 550i that came with staggard 275/30/19 and 245/30/19. The rear rims kept cracking and I found out there were not runflats on the vehicle. I was told runflats were thicker rubber and prevent rim cracks with a low profile tire.
I reluctantly took the sport out of my 550 and went to 245/40/18's all around. I really miss the original sport look. If I put my 19's back on, what tires do you reccommend?
Wednesday, July 11, 2012 by Gary

ALisa,

We have not found that run flat tires prevent rim/wheel cracking. The original 19" sport package size would have been 245/35R19 front and 275/30R19 rear. Top summer tires in that size would be the Michelin Pilot Super Sport and the Continental Extreme Contact DW. For all season tires, I would suggest the Michelin Pilot Sport A/S Plus.
Wednesday, July 18, 2012 by Nancy

I am interested in replacing my original run flat tires- Continental- (2007 328i BMW) with non run flat tires. I see that I can save $$$$$. Can you please suggest a tire that would be suitable. I live in Florida and put less that 12K miles a year on my car. PLease reply soon as my tires are almost at 3 millimeters.

HELP!

Nancy
Thursday, July 19, 2012 by Gary

Nancy,

For value-oriented choices, I like the Continental Extreme Contact DW and Sumitomo HTRZ3 for summer non run flat tires. For all-season non run flat tires, the Kumho ECSTA 4X would be a great choice.
Thursday, July 19, 2012 by Mike

This may seem like a dumb question but why does the ride fail so horribly with 2 RF's on the front and 2 non-RF's on the back?
Monday, July 23, 2012 by Gary

Mike,


This is mainly due to very different levels of sidewall stiffness.
Tuesday, July 24, 2012 by Brian

I just purchased a 2013 BMW 550I (Xdrive). The car came equipped with Good Year Eagle LS 245 40 19 run flat tires ($500 per tire). I live and drive in NYC and have had tire damage to 2 of the tires in less than 1 month since getting the car. Most of the tire damage has been caused by pot holes, which would have been repairable if the tire was non-RF. I am looking for a good all season non-run flat tire that has good performance ratings. I am considering the Good Year (Eagle RSA 245 40 19) all season high performance tire as an alternative. Any comments, suggestions or feedback about these tires would be appreciated.
Tuesday, July 24, 2012 by Gary

Brian,


While the RS-A isn't a bad tire, there are certainly better options available. My top picks for non run flat all season tires in 245/40R19 would be the Michelin Pilot Sport A/S Plus and Kumho ECSTA 4X.
Saturday, July 28, 2012 by Joyce

I need to replace at least 3 tires on my 2009 328i. I have already been through 5 new tires with this car and I am at wits end with these run flat tires. They are terrible!! But because there is no spare, I feel like I have to replace them with run flats. I hate the expensive tires that the BMW dealership uses. Any suggestions??
Monday, July 30, 2012 by Gary

Unless you're replacing all four tires, it is important to match to the same brand name and model of tire for stable handling. For longer wearing and softer riding run flat tires, check out the Bridgestone RE960 A/S Pole Position RFT.
Monday, July 30, 2012 by Jun

I have a 128 w/ sprt pkg...can you suggest a RFT or non-RFT that would provide a smoother ride? Currently installed RFT is the Goodyear Eagle NCT. Thanks!
Tuesday, July 31, 2012 by Gary

Jun,

For run flat tires in 205/50R17 and 225/415R17, the Michelin Primacy HP ZP would have the smoothest ride. For non run flat tires, consider the Yokohama Avid Ascend and Continental Extreme Contact DWS would be excellent smoother riding tires.
Wednesday, August 1, 2012 by John

I've already replaced both front Potenza RFTs on my 2009 335i due to wall bubbles. Now the rears are worn and need replacing. I want to replace rears only with Michelin Pilot Sport PS2 ZPs, but sounds like mixing brands isn't recommended. Can I get away with this? I'd rather get away from the Bridgestones.
Wednesday, August 1, 2012 by Gary

John,

While you can "get away with" mixing tires, you are correct that it is not ideal. Mixing is not recommended due to less stable handling in tight corners, emergency maneuvers and highway speeds.
Sunday, August 5, 2012 by David

I just purchased a cpo 2008 BMW 335i with sport package which came with new OEM Bridgestone Potenza RFT 18 inch tires. I do not like the harsh ride of those tires. I had a loaner 2012 BMW 328 coupe (sport suspension) with 17 inch all season tires and really liked the balance of handling, ride comfort and steering effort that car had but I don't recall the tire brand and model.

To improve the ride quality of my 2008 335i to be similar in handling and comfort to the loaner car I had, which of the following do you recommend as I am open to summer performance or all season tires (I live in San Francisco):

1) Stay with 18inch wheels but go with a different RFT? If so, which one?
2) Stay with 18inch wheels but go with a conventional tire? If so, which one?
3) Get 17inch wheels but go with a different RFT? If so, which one?
4) Get 17inch wheels but go with a conventional tire? If so, which one?

Will changing tires and/or wheels have a noticeable impact on steering effort?

If I go with conventional tires, do I need tire pressure monitor sensors installed?

Sorry for the lengthy question. Thanks!
Sunday, August 5, 2012 by jessie

I have a 07 328xit and am on my second set of NRF tires. I still have decent tread on the front but the backs were shot. I replaced them and did a road trip and the ride was terrible. I matched the tires ( Goodyear eagle GT ) that I have on the front and I think I will have to replace the front tires as well. It feels like it is drifting a bit between the front and the back. This never occurred before so I am wondering if it was because of only replacing the back even though the front still have a decent amount of tread. What do you suggest. I wish I would have read the posts earlier and gone with your fire suggestions but it is to late. Any recommendations? Thanks
Sunday, August 5, 2012 by Jon C

Hi, I bought a 2010 BMW 128i about 3 months ago and it is certified. Yesterday both, forward and rear passenger tires, blew out completely. The tires on there at the moment are 205/50r17 RFT's. I need help on whether I need to put 2 new run flats or if I can replace with non run flats. Thank you.
Monday, August 6, 2012 by Gary

David,

The original all season tires on the 2012 was likely the Bridgestone Turnanza El42 or Continental Pro Contact SSR. If you liked either one of those, I would suggest you try the Bridgestone Potenza RE960 A/S Pole Position RFT for either size option. For non run flat tires, check out the Continental Extreme Contact DWS and Kumho ECSTA 4X. Yes, changing tires and/or wheels can have an impact on steering response. TPMS is not required with non run flat tires, but you will have a dash warning light that will stay on if you do not use them.
Monday, August 6, 2012 by Gary

Jessie,

Driving on tires with a large difference in tread depth between the front and rear tires can cause the vehicle to feel a bit unstable. Often times simply allowing the newer tires to break in a wear down a bit can help,. If the difference in tread depth is large then you may want to go ahead and replace worn fronts for best results.
Monday, August 6, 2012 by Gary

Jon,

Unless you are replacing all four tires, it is best to match to the current brand name and model of tire. Mixing different types of tires can cause unstable handling, especially run flats and non run flats.

Gary,

I have a 2011 528i with the 17 inch continental RFT. Iam Considering an 18 inch continental RFT. I was told that I would need to have spacers on the new wheels. Is that required and what good series RFT for continental would you reccomend?
Thursday, August 9, 2012 by Gary

Andre,

None of the wheels that we sell require spacers, but you should check with the store you are buying your wheels from to confirm whether or not their wheels require them. For an all-season 18", check out the Continental Pro Contact SSR.

I have a 2011 535xi with 30K miles on it. The shop says that the front tires are "chopped" and that's what's causing the road noise. What do you recommend for both a run flat as well as a non-run flat replacement? Thanks!
Friday, August 10, 2012 by Gary

Unless you're replacing all four tires, it is important to match to the same brand name and model of tire that you're keeping on the rear for stable handling. If you're replacing all four, the Bridgestone Potenza RE960 A/S Pole Position RFT would be a great run flat replacement. A top non run flat replacement tire would be the Michelin Pilot Sport A/S Plus

I had a 2006 330i with RFT and hated them. I went through about 4 sets of tires in 4 years, the roads here are not great, however, once it was just going over a speed bump a little too hard. I should note that I have NEVER had this problem with 4 other cars I have driven over the past 15 years, so please don't tell me it's my driving.

Was at the dealership the other day, shopping for a new BMW, and I find that RFT is the *only* way they will sell it. Not getting a BMW until they offer non-RFT tires.

PS: Love TireRack's service, got one of my set of tires from them in the past

I have a 09 335i coupe with sport package. I blew my right rear rft yesterday, entire inside of tire was wore to the belts, I looked around and the strange wear pattern is all over various forums. The rft may of saved my life as it was a complete failure of the tire. The car did not ever shudder, impressed with the car, not with the wear pattern! I would think twice before ditching my rft for standard tires if you have a newer BMW
Thx

I have a 2008 BMW 135 convertible with sport package and 215/40R18 (front) 245/35R18 (rear) with RFT Dunlop SP sport 01 DSST. Looking to switch to non-RFT set of tires. The Dealership said that it would affect the handling of the car... Do you have an idea how that would affect it, and why ? And what set of non-RFT tires would you recommend for my car.
Many Thanks.
Monday, August 20, 2012 by gary

Most non run flat tires in these sizes have softer sidewalls with a bit slower steering response compared to the relatively stiff SP Sport 01 DSST. One non run flat alternative that would maintain much of the handling of the original tires would be the Michelin Pilot Super Sport. If you wish to go to a non run flat tire while maintaining great handling, I would highly recommend this tire.
Thursday, August 23, 2012 by CC

I have a 2007 328i and need to replace all 4 tires. Can you recommend a good, non run flat tire please?
Thank you very much!
Thursday, August 23, 2012 by Derrick

I wish the steering effort on my 2008 BMW 328i coupe with sports package had a little bit light steering as it feels heavy to turn the steering wheel at low speeds. It currently has factory Bridgestone Potenza RFTs. Will getting non-RFT all season tires like the Continental DWS help to lighten steering effort? I assume all season tires would have lower rolling resistance compared to summer tires?
Monday, August 27, 2012 by Gary

CC,

What tire size(s) do you have? Are you looking for an all-season tire?
Monday, August 27, 2012 by Gary

Derrick,

Yes, most have found that the steering feel tends to lighten up a bit when going to a non run-flat all season tire.
Saturday, September 1, 2012 by Bob Dowie

rear tires on my 2007 550i are about gone, but the fronts are only 50% worn. (all Michelin RFT)

the rears are the Michelin RFT "Y" rated that either came with the car or direct replacements.

i'd like to replace the rears with used ones with 50% tread left; and then get all new 4 new RFT's

do you sell used tires (or can recommend a supplier)?
Sunday, September 2, 2012 by Greg

I bought a 2007 335i which I love to drive. I opted for the sports package that came with 225/40 R18 front, 255/35 R18 back run flat tires. I live in NJ and the pot holes are killers. Replaced 6 tires due to bubbles and leaking. I did buy tire/wheel insurance for $600+ originally, and policy maxed out at $3000. Now no insurance left and I am considering non run flat tires. Wife hates the firm ride, and I want all season tires - dealer and many folks recommend not to drive in ice/snow. Never have driven in ice/snow but one dealer rep told me it was horrible. Looking for a "donut" option.
Tuesday, September 4, 2012 by Allan

Thinking of changing my RFT 245/55R17 102H Bridgestone on my 2012 X3 w/ conventional tires. What would be best for my X3. Thank you in advance for the info.
Tuesday, September 4, 2012 by Gary

Bob,

I'm sorry, I'm not sure who sells used tires.
Tuesday, September 4, 2012 by Gary

Greg,

I would agree that an all-season tire would generally have a more comfortable ride than a summer tire. We do not carry any complete 'donut' mini spare setups, sorry.
Tuesday, September 4, 2012 by Gary

Allan,

Unfortunately there are no all season non run flat tires made in 245/55R17 as of yet. Perhaps in the future there will be some options for you.
Thursday, September 6, 2012 by Aj

2011 BMW 328XI. Labor day weekend, monday night. Was 300 miles away from NYC, in NH. Slammed onto a pothole at 80 MPH - RFT went flat upto the rimm, and car became un-derivable. My option was to stay with the car or park it and go back to work the next day. Had to call in tow service to the get my car to the nearest airport, about 80 miles - cost $420.

Parked my BMW there, got into a rental, drove back to NYC.

Bought the following the day after:
Wheel: $340
New RFT: $289
RFT pressure value: $168
Tire mount: $55
----------------------------------------------
Total spent: $852

Rental cost: $130
Rental Fuel: $70
----------------------------------------------
Total Rental: $200

----------------------------------------------

Total money spent: $1472
Mental harassment: Limitless!!
----------------------------------------------

This is my true story. Learn from it, avoid RFTs or BMW altogether.

Monday, September 10, 2012 by David

If I am looking for better ride quality and lighter steering feel, which is a better tire choice:
Bridgestone Potenza RE970AS Pole Position or Continental ExtremeContact DWS? Thanks.
Monday, September 10, 2012 by Lee

I am considering switching to non-run flats. Obviously, this gives me a much better selection of tires. But I am concerned about driving with no safety net (no spare and no run flats). How do run flats compare to conventional tires in terms of liklihood of a flat. I drive in New Jersey and the local roads are full of pot holes.
Monday, September 10, 2012 by Gary

David,

Both would be very similar to each other in both areas with the Bridgestone perhaps having a very slight advantage.
Monday, September 10, 2012 by Gary

Lee,

We have found no difference in the likelihood of tire failure on a run flat compared to a non run flat tire.

Considering all the negative feedback on the Goodyear Eagle LS2's, I am looking to replace these OEM tyres on my 2012 535xi with Non Run flats. What would you recommend? I will have to return the car with the OEM tyres at end of lease.
Friday, September 14, 2012 by Gary

Anil,

Top non run flat all season tires would include the Bridgestone Potenza RE 970 A/S Pole Position and the Michelin Pilot Sport A/S Plus.
Saturday, September 15, 2012 by Rocio

I have had a lot of troubles with RFT (Goodyear Excellence 16R) in my mini Cooper R56 2008 (due to a potholes I've changed 4 front tires in the last 2 years), and now I want to change to a non run flat set..Do you have any suggestion of a good option?
Sunday, September 16, 2012 by Charlette

I have a 06 335I and I have had RFT since I bought the car and the ride is terrible and the tires from beginning were bad and they were RFT as well. Can you recommend some good NRFT tires?
Monday, September 17, 2012 by Gary

Rocio,

Top all-season non run flat tires in 195/55R16 would include the Kumho ECSTA 4X and Yokohama Avid Envigor.
Monday, September 17, 2012 by Gary

Charlette,

What tire size(s) are you using? Are you looking for all-season tires?
Monday, September 17, 2012 by Patti

I have 08 328I with RFT Bridgestone Turanza EL42 original tires with 46,000
miles (205/55R16 91H). BMW dealer states tires will need replacement soon--depth measured
between 4/32nds & 5/32nds.
Have been reading your comments and
considering non RFTs.
Live in Florida and would like tire
that would ride smooth, safe in wet
conditions, quiet, and last of course!
Am so confused with choices of Michelin Pilot Sport, Bridgestone Potenza,etc. as I know nothing about tires! Would appreciate your advise for best choice(s). Thanks
Monday, September 17, 2012 by Gary

An all season tire would provide for better wear and smoother and quieter ride. The best a/s tires I could recommend based on what you're looking for would be the Bridgestone Potenza RE970 A/S Pole Position and the Michelin Pilot Exalto A/S.
Monday, September 17, 2012 by Patti

Gary, thanks so much for your suggestions. You have made the decision so much easier for me.
Thanks again, Patti

09 BMW 128i Coupe/Sports Package....I just need to know the best non-RF tires I can get for this car. Quite & Smooth ride, great handling on dry & wet conditions
Wednesday, September 19, 2012 by Gary

James,

Two top summer performance tire picks for this would be the Continental Extreme Contact DW and the Michelin Pilot Super Sport.
Wednesday, October 3, 2012 by Linda

I drive a 2009 BMW 328i with a little more than 28,000 miles on it. Of the four Pirelli RFT tires, two have picked up nails and have been plugged--one is holding air the other is not. I know that the tires are not supposed to be plugged, but it worked...kind of. Anyway, I have two questions: how long do I have before the tires fail? If I trade the car will the dealer, probably Lexus, prefer that it has RFTS? Thanks for your help!
Wednesday, October 3, 2012 by Gary

Linda,

Unfortunately there is no way to tell how long a tire repair will hold, nor do I know what preference a local dealer will have in regards to tires for a local trade-in, sorry. You may want to check directly with the dealer for details
Sunday, October 7, 2012 by Angelo

Gary,

There seems to be no all-season run flat options for my 2010 BMW 535 GT w/ sports package. Want to switch to non-run flats. Do you think Bridgestone RE970 AS is the best option?
Monday, October 8, 2012 by Gary

Angelo,

If you have the 245/40R19 and 275/35R19 sizes on your 535 GT, Bridgestone makes the RE960 A/S Pole Position Run Flat tire. If you go to a non run flat tire, I would indeed recommend the Potenza RE970 A/S Pole position tire.
Tuesday, October 16, 2012 by Dee

Just purchased a 2007 650i and we want to replace all four tires. We're thinking we'll stay with the RFTs, hopefully, to avoid getting stranded. This car is not a daily driver but it will be driven in dry and wet weather. What tire would you recommend?

Dee
Tuesday, October 16, 2012 by Gary

Dee,

Do you have the 18" or 19" setup on your 2007 BMW 650i?
Wednesday, October 17, 2012 by Dee

Gary,

I've got Bridgestone Potenza tires, 245/35R19 and 275/35R19.

Dee
Wednesday, October 17, 2012 by Gary

Dee,

If you have the 19" wheels on the car, the sizing is normally 245/40R19 front and 275/35R19 rear. The highest rated run flat tires in these sizes are the Dunlop Sport Maxx GT DSST.
Thursday, October 18, 2012 by Dee

Thanks Gary, I'll check them out. Dee
Thursday, October 18, 2012 by Lisa

I am looking to buy a BMW 323i 2007 and was wondering on the averge mileage that the tyres can do before requiring replacement the car has run flats.

Thanks Lisa
Friday, October 19, 2012 by Gary

Lisa,

All tires, even runflat tires, can wear at different rates. What is the brand name and model of tire that you are referring to?
Tuesday, October 23, 2012 by Kent

I have a 2008 335i with sport package PSP ZP(rear 255 35 18). I'm considering the RE 960 AS RFT, but all reviews seem to be about the 225 45 17 tires on cars without sport package. Can anyone comment about the change in ride quality with sport package staggered size set-up?
Wednesday, October 24, 2012 by Gary

The same different would apply in 18". The RE960 A/S will have a noticeably softer ride with a sacrifice in dry grip and steering response.
It is also very important that you do not mix the RE960 A/S with the PS2 ZP as this will cause unstable handling.
Saturday, October 27, 2012 by Mike

I have a 2011 328i with the M Sport Package and just changed from RFT's to the Michelin pilot sport AS plus and the car handles fine. The steering feels a little lighter but the car is quieter and has a better ride. As far as handling goes it feels pretty much the same to me but I don't drive like an idiot either.
Sunday, October 28, 2012 by Erich

I have a 2011 e90 328i with 225/45/17 stock wheels & Continental Contipro-contact SSR run flats. The ride is absolutely bone jarring (even at 30 psi) and so much so that I do not enjoy driving my car! Looking at installing a new set of oem 18" wheels with 225/40/18 tires....either Continental DWS or Bridgestone RE970 A/S. I assume steering will be a bit lighter than before but I would like to know if I can expect less impact harshness? Also which tire would give a better / smoother ride? A tire that balances well is also important since I have had many problems in the past with tires that would not balance properly (I usually run Michelin because of this). Thanks in advance!
Monday, October 29, 2012 by Gary

The Continental Pro Contact SSR is among the softest riding of the run flat tires on the market today. I would not expect you to see a much softer ride with a lower profile non run flat tire. For a more noticeable difference, stick with 225/45R17. The DWS will ride a bit more softly than the RE970 A/S.
Monday, October 29, 2012 by Karl

I am using 205/55R16 Bridgestone Turanza EL42 RFT tires (Canadian 2009 323i premium pkg). I am using this as my daily commute vehicle to drive ~30km to work m(mostly highway). I have absolutely no issues with them. The ride is not too harsh, unlike what many seem to experience (amazing cornering too!). Perhaps, the fact that I use 16" wheels has to do a lot with my overall positive experience. Noise levels are adequate - mostly wind noise at all speeds. The tires are in great shape after 25k and still have plenty of thread left on them. I've driven to Quebec City, Montreal, NYC, Toronto and other pothole-infested areas on the East coast without any problems whatsoever - I ran into a few potholes at highway speeds without any noticeable consequences. So far the way I see it is I get 4 spare tires and extra trunk space. It seems like I am in the minority who has good experience with RFT, and from the looks of it I am definitely in the minority that use 16" wheels on a bmw. However, I can't say that I would have similar opinion if I had to commute through the country roads on daily basis...

My personal experience as well as reading other posts and forums suggests that 2nd generation RFT's are quite good for smaller diameter wheels (i.e.
Wednesday, October 31, 2012 by Scott

I own a 2010 BMW X5 diesel. I am on my 2nd set of 19inch Bridgestone Dueler HL. No complaints about the life of these, but I am getting a bit tired of the "heavy" steering at low speeds and while parking. Do you think that switching to non-run-flats would help? If so, what do you suggest? My current tires are fairly quiet and I would like to keep it that way. Thanks,
Wednesday, October 31, 2012 by justin

I have a 2008 135I convertable M-sport with factory rims installed. I am looking for the best winter tire for canadian winters, with snow and good dry traction in Runflat or not. I read a review on the Winter Sottozero Serie II Run Flat, which said it was awful for snow. I like that this tire comes in the factory size to fit on my 18's. Can you recommend another tire, Run flat or not that can be used for my rim this winter. thanks
Wednesday, October 31, 2012 by Gary

Scott,

While I doubt the steering would lighten up much at low speeds by gong to a non run flat tire, you can get a tire that has a softer ride and better traction in the 255/50R19 size by going to the Pirelli Scorpion Verde A/S.
Wednesday, October 31, 2012 by Gary

On the 135i you can use size 225/40R18 on all four factory wheels with no problem. In this size you can get the Bridgestone Blizzak LM60 RFT which would be much better in snow and ice than the Pirelli Sotto Zero Serie II tires.
Wednesday, October 31, 2012 by Robert Coutts

I am looking to replace my front tyres on my BMW x5 Dueller 275/40R20 106W. The RFTs on the back wheels are virtually new so can keep them on the car and replace non-RFT on the front wheels-and any suggestions?
Wednesday, October 31, 2012 by Gary

Robert,

Avoid mixing run flat and non run flat tires due to unstable handling, especially at highway speeds and in turns.
Thursday, November 1, 2012 by Rob

I have a 2005 Z4 with American Specs and I live in Germany. As you know, we can go a little faster on certain highways here. I would like to go non-RFT. I currently have 16" RFT and would like to go 17" or 18" rims and tires. Question 1: If I purchase rims with TR, will the sensors (if purchased)work with the computer? Question 2: Tire recommendation (would like All-Season non-RFT) for a good riding tire with a higher speed rating?
Thursday, November 1, 2012 by Gary

The 2005 Z4 does not use TPMS sensors, but instead has an ABS based system that does not use actual sensors.

Top choices for non run flat all season tires with good ride quality would include the Bridgestone Serenity Plus and Continental Extreme Contact DWS.
Thursday, November 1, 2012 by Kent

I have 2009 X5 BMW xDrive 48i Sport Package with Run Flats (came with Michelin 255/50 R 19 XL RSC) and no spare tire. Considering Non-Run Flats, anyone try this with no spare and a paid up AAA membership? Any suggestions for a Non-Run Flat?
Wednesday, November 7, 2012 by Gary

Kent,

Both the Pirelli Scorpion Verde A/S and Continental Cross Contact LX20 would be excellent choices for the 2009 X5 in 255/50R19.
Thursday, November 8, 2012 by Darryl

I want to ditch the run flats on my 2010 BMW 335i with sport package and go with conventional tires but not sure if I want to go with summer or all season tires. I am deciding between the Michelin Pilot Super Sport or Bridgestone Potenza RE970AS.

There is no snow where I live. How do the 2 tires compare in terms of ride comfort/quality/noise and handling? I assume the all seasons will last longer.
Friday, November 9, 2012 by curt

2013 128i; best non-rft to replace stock rfts (17")? where to get spare donut tire kit? Thanks for your help
Friday, November 9, 2012 by Gary

Darryl,

The Pilot Super Sport would should see about 30,000 miles compared to about 50,000 miles from the RE970 A/S. The Super Sport has faster steering response for better handling and more dry grip, but will ride more firmly than the RE970 A/S.
Friday, November 9, 2012 by Gary

Curt,

I'm sorry, we are not sure where to find a spare tire kit for this vehicle. There are some good tire recommendations in my comments above, including the RE970A/S and Michelin Pilot Super Sport.
Monday, November 12, 2012 by Jerry

What all season tires would you recommend for a 2008 BMW 328xi Coupe? Present tires are 225/45-17 RFT.
Monday, November 12, 2012 by Gary

Jerry,

Two of the best all season runflat tires in 225/45R17 would be the Bridgestone Potenza RE960 A/S Pole Position RFT and the Pirelli PZero Nero A/S RFT.
Tuesday, November 13, 2012 by Jerry

Gary,

After reading most of the comments on this blog, I am considering dumping the RFT tires for conventional. Would your tire recommendations be the same?
Tuesday, November 13, 2012 by jim

I just got a new 550 and was surprised by not having a donut spare.
i usually get the tire insurance but on this lease they raised it to $1,700.
I usually drive on non RF for the winter because of pot holes. The tires that cam with the car have a larger profile and seeem quieter and not as hard a ride.
Does anyone sell a donut and jack kit for the 2023 models?
Jim
Wednesday, November 14, 2012 by Mike

2013 BMW 128i M Sport. I cannot find run-flat all seasons that fit my car. Nervous about going through Maryland winter on summer tires. Kind of thinking of going non-runflat all season, not winter tires, but unsure what to get. Value sharp handling but also need decent ability to deal with snow. Advice would be most welcome.
Wednesday, November 14, 2012 by Mike

Another question: OEM tires on back are 225/45R17. If I put 235/45R17 on the back I can use Michelin Pilot Exaltos, a great tire. (Identical replacements for the OEM 205/50R17s are available in that tire.) What would be impact of using that slightly wider tire in rear? Bad idea?
Wednesday, November 14, 2012 by Kevin

I just got a 2008 BMW 335i Coupe sports package with the staggered set-up. What would you recommend for an all season non RF? What do you recommend for RFT?
Wednesday, November 14, 2012 by Gary

MIke,

235/45R17 will indeed fit the rear with no problem. The Michelin Pilot Exalto A/S would be an outstanding choice for a good all season non run flat tire. For an all-season with better steering response and a bit sharper handling, check out the Michelin Pilot Sport A/S Plus.
Wednesday, November 14, 2012 by Gary

Kevin,

Top all season non run flat tires in the staggered 18" sizes would include the Michelin Sport A/S plus and Bridgestone Potenza RE970 A/S Pole Position. The only run flat all season tire made in both sizes is the Bridgestone Potenza RE960 A/S RFT.

Gary, Currently running 4 x Goodyear 245/40/R18 93Y RFT on a 2007 550i Sports E61 Touring model for over 14 months and I can find a million escuses not to drive it due to the very hard and very harsh ride. I have punctures in 2 tyres at this momment. Glad to have come across this excellent site. I like the idea of RFT's but I would like a recommendation to change all my tyres so I can start enjoying driving my motor! Gary I've had non-run flats Michelin Sports on my previous BMW's and found them to best handeling drive ever! What do you recommend? Will the Michelin RFT vs non- runflats or what is best suited for a more comfortable drive? Thanks.
Friday, November 16, 2012 by Mike

Thanks Gary. One more question: Would it be okay to square up with new tires? And should they be the 225/45-17s as are currently on back or the 205/50-17s currently on the front, or some other size? Any handling issues posed by squaring up? I hear there would be less understeer.
Friday, November 16, 2012 by Gary

Pete,

You'll find a softer ride with non run flats, and the Pilot Super Sport is indeed our top summer performance tire in that category.
Friday, November 16, 2012 by Gary

The rear 17X8.5 wheels are a bit too wide to use 205/50R17, so if you use a square setup stick with 225/45R17 all around. Typically a square setup will result in more neutral handling.
Friday, November 16, 2012 by Marshall

Need to replace the Michelin ZP's on my 2011 335D Sport Pkg. I want to stick with Michelin but go to a non run flat model smoother riding tire. Suggestions?
Saturday, November 17, 2012 by Mike

Actually I have 17x7s and 17x7.5s. From your web pages, looks like the max wheel width is 7.5 for the 205/50-R17s. Is there any problem with being right at the maximum wheel width? Will I have clearance issues if I put Exaltos in that size on rear of my 128?
Saturday, November 17, 2012 by Evan

My wife has a 328I convertible with 225S run flats, can I change that to 245s non run flats?
Monday, November 19, 2012 by Gary

Marshall,

The Michelin Pilot Super Sport would be the way to go for a non run flat summer performance tire in the staggered 18" sizes on the 2011 335D. For all season tires, the Pilot Sport A/S plus would be the way to go.
Monday, November 19, 2012 by Gary

Mike,

There is no problem with being on the end of the recommended rim width range. 205/50R17 will fit front and rear with no problem.
Monday, November 19, 2012 by Gary

Evan,

245 width tires are generally too large to fit up front on most three series cars.
Thursday, November 22, 2012 by Erica

Gary,

The article and posts have been very informative. I recently bought a 2009 135i sport with the OEM 18" run flats. My husband will tell you I did not research enough ahead of time. I've had constant problems with the noise on the tires and thought there was a mechanical issue, only to be told that the noise was being caused by "tire shine" applied to the tires. Right... After looking at multiple blogs, it appears as if they are the tires themselves. I live in Northern Virginia and it looks like I need winter tires also. Since I hate the existing tires and need to replace them (still unsure of RFT vs. non) are there good all season tires that would work with the 135 sport so I don't need 2 sets?

Thank you!
Saturday, November 24, 2012 by jim

Hello,
Aside from the cost of the tires, is there any additional cost to non-RFT's? I have a 2008 535xi with sports package and I am being told it will cost 3-4K to make the change to non-RFT's. The tires are Dunlops, 245/40R18 (front) and 275/35R18 (back)
Thanks!
Saturday, December 1, 2012 by Ken

Seeking non-RFT replacements for 2008 BMWxi (39K miles on original RFT's). I live in NJ, and need an all-season tire reliable in snow and that can stand up to numerous and proliferating potholes. Suggestions? Thanks
Monday, December 3, 2012 by Dj

I have a 2007 335i w/sports. So obviously it has RFTs. I am tired of the noise and ride discomfort that RFts are causing. If I wanted to put Non RFTs on my car, should I buy new wheels that are suitable for Non RFTs. Or can I put Non RFTs on the wheels I currently have???

Please suggest. DJ
Tuesday, December 4, 2012 by Gary

Non run flat tires can indeed fit the factory wheels with no problem.

Own a 2008 328I convertible. Tires are Bridgestone/EL42 225/45 17 91H run flat w/20,000 miles. Ride is very firm and I need to replace my 2nd tire due to nail. Can I replace 2 rear tires with non run flats? If not, can you recommend non-runflats that would result in smoother ride? I live in Florida. Thanks

I have a 2011 335is conv w/M sport package, At 21k I was told my tires are cupping which I always thought was from bad alignment etc and that I need 4 new tires at 2200. They are protenza run flats and apparently they are different sizes on the front and the back. I drive it on the highway to and from work. Isnt that kind of early to be replacing tires and do I have to go back to run flats. It hardly seems worth it if Im going to have to replace them every year and a half
Wednesday, December 5, 2012 by Gary

Carlos,

Avoid mixing run flats with non run flats as this can cause unstable handling, especially in corners and at highway speeds. Softer riding non run flat tires in 225/45R17 would include the Bridgestone Turanza Serenity Plus, and Continental Pure Contact.

I am looking to replace tires on my 2008 335i. Can you suggest RF tires and non RF tires I can consider for best rain/snow handling in NJ.
Sunday, December 9, 2012 by Brad

2010 328i xdrive with stock 225/45R17 Conti's RFT. Losing one pound of pressure per day can can't find a local shop to even talk about repair. If I go to RE970AS non RFT can I also expect a ride improvement? I know the Conti ride is supposed to be decent but to me in 17" it's pretty brutal.
Monday, December 10, 2012 by Gary

Ken,

Top all season non run flat tires would include the Continental Extreme Contact DWS and Bridgestone Potenza RE970 A/S Pole Position.
Monday, December 10, 2012 by Gary

Brad,

If you have the Conti Pro Contact SSR, I would not expect you to see much of an improvement in ride by going to the Bridgestone RE970 A/S. For a more noticeable improvement in ride, I'd suggest the Bridgestone Turanza Serenity Plus or Kumho ECSTA LX Platinum.

I need to replace Bridgestone Potenza RFT on 2007 BMW 328xi, 225/45R17 which have 60,000 miles on them. The wear has been great, but I would like recommendations for tires in both run flat and non run flat that should provide a smoother, quiter ride. Bumping up the width to 235 would beno problem. Live in Houston and would like a tire that has good grip I wet roads.
Wednesday, December 26, 2012 by Gary

Jay,

I'm not sure of another source for BMW original wheels, sorry. If you're just replacing one or two tires, it is important to match to your existing tires.
Wednesday, December 26, 2012 by Gary

For a softer ride, top run flat choices are the Bridgestone Potenza RE960 A/S RFT and Continental Pro Contact SSR. A highly rated non run flat would be the Bridgestone Turanza Serenity Plus.

Hi Gary,
I have a 2008 BMW 335i, I just got a bubble in my front left tire after i hit a curb, I have run flat tires, how safe is it to drive on that small bubble? Also if i were to consider going to a non runflat tire if i have to replace, what would be the best option in your opinion for all season tires, reliabilty, etc.
Saturday, December 29, 2012 by Rob

My son is buying a used 2008 BMW 328xi in incredible condition. I did some research on the RFT and told the dealership we wouldn't buy it with those on it. They asked me what I wanted and told them Michelin Defenders (Tirerack and Consumer Reports high ratings). When he picks it up, I will report on how they are. They just seem so much better than the RFT. Thoughts?
Wednesday, January 2, 2013 by Gary

Manish,

A bubble is an indication that the inner liner of the tire is torn and air is beginning to migrate out of the tire. Tire failures from bubbles are very unpredictable in regards to how long one can safely drive on the the tire after seeing a bubble, so I have to advise you to replace it as soon as possible.
Wednesday, January 2, 2013 by Gary

Rob,

The Michelin Defender will be quieter and have longer wear than most run flat tires. It is a good choice for the car if the owners driving style is not aggressive.
Friday, January 11, 2013 by BJ

I have a 2011 550ix (xdrive) and need new RFTs. I want the best. Looking for all season excellent performance and smooth handling with ability to handle all speeds. Original tires are Bridgestone RFT but I am not impressed per se with handling on curves with any speed, nor on wet pavement (more slipping) and they lose air quickly. Have never had RFTs before this car so not sure if that is the difference in performance or simply the brand of RFT.

I have a 2012 535xi and want to replace my RFT with Michelin Pilot Sport A/S Plus. Do I need to be concerned that the tire sensor and more importantly the suspension need to be adjusted?
Sunday, January 13, 2013 by Carl Williams

I currently have Bridgestone Portenza RFT. I need to replace the rear set of tires and it seems that the Michelin RFTs. They front tires are relatively new can I just replace the rear tires or will this cause stability issues?
Monday, January 14, 2013 by Gary

BJ,

I can check on this for you. What tire size(s) are you using?
Monday, January 14, 2013 by Gary

Stef,

No adjustment to the TPMS sensor or vehicle suspension would be needed when changing to non run flat tires.
Monday, January 14, 2013 by Gary

Carl,

We definitely recommend against mixing different models of tires due to stability issues. It is best to stick with the same brand and model of tire unless replacing all four tires.

I do drive aggressively (it is a performance car :)) but I do a lot of highway driving during work week; I am between two tires I think would work best for my 2005 BMW 330xi - 205/50/17 93v needs the Michelin Pilot MXM4 or Bridgestone Turanza Serenity plus - what do you recommend?
Monday, January 21, 2013 by Ferhat

Just ditched RFs today. I bought Michelin Pilot Sports A/S Plus from costco for a total cost of $930 everything included. I live in Seattle and go to Portland a lot and the ruts on I5 were a big issue with RFs. I will let you guys know about my non-RF experience. Thanks for all the info here..
Monday, January 21, 2013 by Gary

Customer survey and testing data seem to indicate that the Bridgestone Turanza Serenity Plus is a superior tire compared to the older Michelin Pilot HX MXM4 tire.

Three months after getting E61 with RFTs I replaced with Hankook V12 Evo non-RFTs. No problem with electronics and still warn me when one tires had slow leak. It simply measures the difference in rate. Aside from cost u get choice and comfort and quiet rides. Can't be happier. I have also tried Continental CSC5 which is even better but wears quite fast. I use 98Y XL. I think XL is recommended and definitely dun mix RFT and non-RFT but I mixed front-back pair with no problems. Hope it helps.

I have a 2009 335xi Coupe with sport package and OEM Bridgestone Turanza's 225/45/17's (front & back) that need replacing. My dealer is insistant I stay with RFT's but I'd prefer to change to non-RFTs. All the reviews elude that the RFT's, while harsh and noisy, are not so great in snow & rain. That seems to negate the point of the Xdrive. Just a few days ago we had 2 seperate multi-car pileups. (one 80+ cars, another 50+) I want to know my car has a chance of stopping. What All Season choices do you recommend that can handle the elements? Both RFT & non-RFT.
Thursday, January 24, 2013 by Gary

Top all season run flat tires are the Continental Pro Contact SSR and Bridgestone Potenza RE960 A/S RFT. For non run flats, check out the Michelin Pilot Sport A/S Plus and Bridgestone Potenza RE970 A/S.

E61 stock is 225/50 R17. I also used non-RFT for winter tires in addition to non-RFT summer tires mentioned earlier. It's even comfier than the summer non-RFT and rides amazingly well even at 95mph. Btw I added a space saver spare when I switched from RFT - E61 tourer has dedicated boot space for it. This spring, I'm contemplating using 235/45 R17 on the stock 7.5" rim. Has anyone tried this and has any feedback? Thanks.
Thursday, January 31, 2013 by Gary

We have not had any experience or feedback with the shorter and wider 235/45R17 size on the E61, sorry. 245/45R17 does fit and maintains the correct overall diameter.

I just bought a 2013 X5 diesel with run flat tires on 20 inch rims. Tires are Dunlap. The X5 runs rough and steers hard. On a smooth road it steers great BUT on a rough road is wanders to the right and left and I really have to grip the steering wheel. It's like driving on bias tires. Your suggestions please. Is it the tires?
Monday, February 25, 2013 by Gary

Ron,

The wandering you're referring to is called tramlining.

The factory 20" option on your vehicle is normally the Dunlop SP Sport Maxx ROF. This tires directional tread pattern and high performance nature will tend to tramline more than other tires. You may want to consider the other tire that BMW uses on this vehicle from the factory for less tramlining : The Bridgestone Dueler HP Sport RFT.

Would you pay the extra $$ for the Michellin?
Monday, March 18, 2013 by Gary

Both are great tires. Between these two tires, the Continental Extreme Contact DWS has better snow traction and a softer ride, while the Michelin Pilot Sport A/S Plus has faster steering response and a bit better handling/grip.

I just did the deed, I ordered a set of 18" wheels from tire rack mounted with Michelin Pilot Sport's for my BMW 335xi. I put them on the car last night and drove it to work this morning. What a difference.

The car came from the factory with 17" wheels mounted with the infamous run flat tires. Those wore out at 20,000 miles, and I replaced them with some Bridgestone Pole Position RFT's, which were supposedly an improved design. My experience with both sets was equally awful. Potholes that wouldnt make you bat an eyelash with normal tires caused a KaBoom that made me wonder if a grenade just went off in my wheel well. On a wide sweeping turn, the car would skip and hop through the turn if it encountered rough pavement, as if you were running a race suspension.

Switching back to normal tires has been a revelation. I realize I am driving a superbly engineered street car, and not a go kart with a 3.0L twin turbo. The move from 17" to 18" normally causes a harsher ride... but coming from RFT's it is like I am riding on gossamer wings.

I went out and got an E90 compact spare kit (BMW does make such a thing) which comes with the tire, jack, and wrench. The jack/wrench kit comes in a zippered pouch and fits in the little compartment under the floor of the trunk. The spare comes with a zippered storage pouch, and you just put it in the trunk and tie it down. I'd rather lose a little trunk space and possible change a tire on the road once every two years than drive around in a $50,000 car that has the road feel of a stagecoach.

I understand that Michelin has a run flat version of the Pilot Sport that solves all of these problems and runs like a regular tire. Well maybe so, but I find it hard to believe.

If you are finding your current run flats unacceptable, and are willing to take on the risk that you will get a flat and have to change a tire at some point, I would encourage you to try a set of regular tires because I can guarantee that you will have a better driving experience. I personally would not want to spend another $1200 on the latest RFT technology and be stuck with them for another 2 years on the chance that Michelin has done what has never been done before: produce an RFT that doesn't leave you thinking about how much you hate RFT's every time you drive your car.

I was told by a friend who knows tires that I should opt out of the run flats and get a good michellin non run flat. I am so confused?? please advise??
Monday, April 1, 2013 by Gary

Frank,

If you have the factory 18" wheels with 245/45R18, top all season run flat tires that I would suggest are the Bridgestone Potenza RE960 A/S Pole Position RFT, and Continental Pro Contact SSR. If you opt for non run flat tires instead, check out the Michelin Pilot Sport A/S Plus or Bridgestone Potenza RE970 A/S Pole Position. Among these choices, the non run flat tires have a bit softer ride, but shower turn-in/steering response compared to the run flat tires I suggested.

Sunday, April 14, 2013 by Satchel

I used to have a 2003 BMW 330i with the sports package and regular all season tires. I loved the handling, ride quality that was just right without being harsh and the steering was tight enough and not loose to give good road feedback. I decided to get a CPO 2008 335i with the sports package and Bridestone 050A RFT expecting the same or even better satisfaction but have been sadly disappointed. The 2008 335i has a ride that is very stiff and steering that feels very tight that almost feels like a workout every time I drive.

Will switching to all season non RFT tires help get my 2008 335i to feel and handle like my old 2003 330i?

The difference between the two is in snow traction versus handling. The DWS has better snow capability while the ECSTA 4X has better handling and faster steering response.

While the Pro Contact isn't a bad choice there are better options for a smooth, quiet riding tire with good wear. I'd suggest considering the Bridgestone Turanza Serenity Plus, Michelin Primacy MXV4, and Continental Pure Contact.

Need A/S tires - 245/45 R17 for 525i that currently has the Michelin Pilot Sport A/S Plus ZP bought from Tirerack. Tires were great but tread is 2/32 in only 15K miles (2.5 years) for mostly city driving. What would you recommend replacing with? Another set of RFTs (Potenza RE 960 A/S RFT or the new Pirelli Pzero A/S). This car came with OEM RFTs (Potenza summer) - can I replace with non RFTs (last time, dealer was recommending Conti Extreme Contact DWS) or will this result in TPMS or Active Steering alerts? I am in New England - so handling in snow is important.
Wednesday, June 5, 2013 by Gary

Amani,

Are you looking for the best summer performance tires for handling and steering response, or more for all-season tires with a quiet ride and longer tread wear?
Wednesday, June 5, 2013 by Gary

Ashu,

You can indeed replace all four tires with a non runflat tire like the Continental Extreme Contact DWS without causing any problems with TPMS or other vehicle stability systems. If you decide to stick with a run flat design, the Continental Pro Contact SSR has the longest wear in 245/45R17.

any problem replacing RFTs with nonRFTs on 2006 Corvette?
Thursday, June 6, 2013 by Gary

Rob,

As long as you are replacing all four tires with matching non run flat tires, this would no problem.

I have a 2006 BMW 325xi. When it was time to replace the original run-flats, I opted to go with regular tires. That was 45K miles ago and I've had no problem with the tires and the car drives very well. Sure, there is no spare and if I get a flat it means calling for a tow to the nearest garage for a new tire. But with the run-flats there would be no guarantee that I'd be able to get a replacement tire in a timely manner if I got stuck somewhere. It will be time for new tires again before next winter and I will go with regular tires again. I did invest in an emergency roadside kit with a tire inflator that plugs into the 9V in the car, but that may not help much, if at all, if I get a flat.

I have a BMW Z4 with 18 inch wheels and RFT. The tramlining is so bad with this car that it scares me to drive it over 50. I'm switching to non RFTs next week. Shame on BMW

I can check on this for you. What tire size(s) are you using?
Saturday, June 29, 2013 by Tim

Gary, I have a 2011 BMW 535ix with 32,000 miles. The OEM tires were replaced at 12,000 miles with Continental ProContact SSR 245/45 R18 tires because the OEM tires were cupped and worn. The replacement tires are now shot - with the same reported problem. Any recommendations on a replacement RFT that will have a comfortable ride with a long wear life?

I have a 2012 M3 convertible with Michelin RFTs as OEM (front 245/35ZR19; rear - 265/35ZR19) The tread life on the rears is 10,000 miles; I use the car as my daily driver with a combination of highway and city driving. this car will never see the track as long as I'm owning it. is there a tire option for a good ride, decent handling, quiet ride, with a significantly longer tread life? anything over 20,000 miles would be a big improvement. (keeping in mind that with different size tires, rotation is not available, so the warranty is cut in 1/2 for the tires on this car.) I am open to either RFT's or non-RFT's. what is my best option?
Monday, July 1, 2013 by Gary

Tim,

The two longest wearing run flat tires in 245/45R18 would be the Bridgestone Potenza RE960 A/S Pole Position RFT and Continental Pro Contact SSR. Given that you have not had good luck with the Pro Contact SSR, you may want to give the RE960 A/S Pole Position RFT a try.

Monday, July 1, 2013 by Gary

Dean,

Run flat tires are not available in these sizes. The longest wearing tires in these sizes would be the Michelin Pilot Sport AS3, however this tire would be a step down in handing, dry grip and steering response compared to a summer performance tire. Top summer tires in these sizes would include the Michelin Pilot Super Sport, Bridgestone S04 Pole Position and Continental Extreme Contact DW.

I have a 2006 325i and am down to about 1 mm of tread on my rear tires. The previous owner has managed to viscously scratch every single wheel so I am looking into just replacing all four wheels and tires and switching to non-run flat. Will I have any issues moving up from a 17" rim to 18"? If not need recommended tire/wheel combo that won't cost me an arm and a leg. Prefer some sort of black 5 or 6 spoke 18"s. Thanks.
Tuesday, July 2, 2013 by Gary

B.J.,

18" wheels work great on the 2006 BMW 325i and are the size that most upgrade to when replacing their wheels. Your best pricing will likely be found by using the same wheel size all around, typically 18X8 or 18X8.5 with tire size 225/40R18. We have many choices that fit, check out our complete selection here : http://www.tirerack.com/wheels/wtpack.jsp?affiliate=FH8

Yes, you can indeed move to non run flat tires on your vehicle without having problems with the TPMS light staying on. I am unaware of any temporary spare wheel/tire solutions, sorry.

Gary, I have a 2010 BMW 535i with Dunlop SP Sport 01 run flat tires on front and back. Both front tires are completely worn (down to the interior fiber of the tires) on the inside shoulders after only about 22,000 miles. I live in Houston, TX so lots of heat and rain driving but no snow. Can you recommend RFT's and non-RFT's that will give me better tread life?
Monday, July 15, 2013 by Kai

I have a 2008 BMW 528i. I hate the loud road noise of my factory run flats and would like a smoother ride. Do you still recommend the Michelin Pilot Super Sport. I live in Texas and i do a lot of highway and street driving.
Monday, July 15, 2013 by Gary

Greg,

It is very important to match to the same brand and model of tire if you are just replacing two tires.

If you're replacing all four tires, which tires size(s) are you using?
Monday, July 15, 2013 by Gary

Kai,

I am a big fan of the Michelin Pilot Super Sport for our top Max Performance summer tire. For a tire with an even quieter and softer ride with some sacrifice to handling and steering response, check out the Continental Extreme Contact DW.

Top non run flat choices in these sizes for longer tread life include the Continental Extreme Contact DWS and Hankook Ventus S1 Noble2. For a run flat tire in these sizes with long wear, check out the Bridgestone Potenza RE960 A/S Pole Position RFT.

I am considering switching from run flats to non run flats. Can you recommend some brands for me? Thank you.

If just replacing two tires, it is very important to match to the same brand name and model of your other two tires.

I'm at my witt's end with run flats. I replaced all 4 on my one year old x3 in dec.
Now 7 months later in told all 4 need to be replaced. I haven't put crazy mileage on it. I don't have $2,000 for tires twice a year :( my husband wants me to switch to traditional tires. Did you need new rims to do it or do they work on the BMW factory rims?

Yes, you can indeed install non-run flat traditional tires on your factory BMW wheels with no problem.

Hi Gary, I have a 2012 740Li that has Dunlop SP Sport Max GT run flats and I'm looking to replace them with non-run flats for a quieter ride and longer life. These tires have less than 24,000 and are worn out with cupping. I live in South Texas so it's never cold, snows once in a hundred years, and only occasionally rains. What do you recommend as a good compromise between performance and long life? Thank you.
Friday, July 26, 2013 by Don Ivo

Do I need to replace all 4 run-flat tires if only one is bad? I have a 2007 BMW 328 xi purchased from a BMW dealer as "pre-certified" three months ago. A tire dealer suggested that "all 4 tires must be replaced because you have an AWD vehicle." Please advise. Thanks in advance.
Friday, July 26, 2013 by Glenn Maley

Gary,

Things have escalated in my world as I have one rear tire that is at the wear bars and the other supposedly (haven't seen it, dealer says so) has a nail. I had been considering switching over to non run flats already and now am really looking at it since replacing both rears with OEM Bridgestone RE050A RFTs will cost me almost as much as going non run flat all around. 2007 328i convertible with sport package on 18" wheels, so 225/40-18s up front, 255/35-18s on the back. Mostly drive to and from local customers and to and from the airport in Dallas suburbs with an occasional longer trip thrown in. 6K miles per year on average. I do like the feel of the sport suspension sticking to the road but not necessarily the bumpiness or bottoming out on speed bumps. Suggestions?
Monday, July 29, 2013 by Steve

Hey, I am thinking about putting non-run flats on my 328. Are there any issues with doing this as it relates to the TPMS? I would think not...
Monday, July 29, 2013 by Gary

Glenn,

Going to a non run flat tire will result in a softer ride, but will be less responsive than your run flat Bridgestone Potenza RE050A tires. Most are still happy with the tradeoff when going to a max performance non run flat tire such as the Michelin Pilot Super Sport or Bridgestone Potenza S04 Pole Position.

Yes, all wheel drive vehicles can be sensitive to using tires with different tread depths. Damage to the AWD system can occur if tread depths are not closely matched.
Monday, July 29, 2013 by Gary

Correct, the TPMS system is not affected by using non run flat tires.

Gary, For my 328i sports package, what about the Conti DWS?

The Continental Extreme Contact DWS would be a large step down in grip and steering response from the RE050A or Bridgestone S04, but it would have a softer ride and longer wear.

I am looking to replace tires on a BMW 335i Convert with 19" Sport Wheel package. Front tires are 225/35R19 - Rear is 255/30R19. Can I use a 255/35R19 instead on the rear (matching from aspect ratio)?? This would widen my tire options with Michelin - and I would prefer the new AS3 Pilots. Thanks in advance
Thursday, August 1, 2013 by Gary

255/35R19 is too tall and normally rubs.

Keep in mind that 225/35R19 and 255/30R19 are the same height, but 255/35R19 is a full inch taller. Mixing different diameters from front to rear can cause problems with traction control and ABS.

Gary...I am considering replacing my Bridgestone Potenza Run Flats on my 2011 328i Xdrive coupe with sport package (18" staggered set up with the wider tires in back) ...I'm making a long (200 mile) daily commute and I drive aggressively AND rally on the weekends...so I want handling. My fear is the RFs will leave me in the middle of nowhere after I use their 50 miles of safety if I have a flat. Also...really need all season and don't want to buy winter tires...thoughts?
Thursday, August 1, 2013 by Jim

Gary, I recently bought a 2001 Corvette with 14,000 miles. It has the Z51 suspension. The tires appear to be the original Goodyear Eagle run flats and they're starting to crack.

I purposely bought a Z51 because I wanted the added handling capabilities. From all the research I've done on run-flat tires I really don't think I want them. But I'm concerned that a non-run flat version of a run-flat tire will, with its softer sidewall, not have the same level of grip in turns. Can you address the handling issue?
Thursday, August 1, 2013 by Gary

Jim,

Generally speaking, non run flat tires are not as stiff, which typically translates into a softer ride, but slower steering response.
Friday, August 2, 2013 by Jim

Gary,

Thanks. Another question occurs to me.

Which will generally use less gas, a run flat, or a non-fun flat version of the same tire (Goodyear Eagle F1's come to mind)?
Monday, August 5, 2013 by Gary

Unfortunately we have not tested fuel economy difference between run flat and non run flat tire models, but typically the differences in fuel economy among tires in the same size is not that large.

I am unsatisfied with the ride of my 2011 bmw335i xdrive sedan with sport suspension. I just purchased this car from a dealer as a two year left over vehicle (had 300 miles on it ). If I can solve the problem of the run flats transmitting every dimple in the road felt in the cabin this would be the perfect car. It's responsive fast and luxurious. The tires in the front are bridgstone potenza 225 / 40 R18 88 W and 225 / 35 R18 90W in the rears. I suspect these are not going to fare well in the winters here in the north east (western Mass). I'm willing to get a second set of rims and have them dedicated to snow tires. If I go this route should I go down to 17 inch rims for the winter set ? What winter snow tire do you recommend and since the fronts and backs in the factory set up are different sizes should the winter set be staggered as well? If I get new rims should I also get pressure monitoring valve stems so the TPMS has something to monitor or will it read error? I'm not opposed to throwing a donut spare and jack in the trunk and go with non runflats. I'm also not opposed to an all season tire for the stock rims to avoid buying a second set if they will take the road noise out . Help!!!!!

I have a 2012 BMW x3 and a 2012 bmw x1. Both are equipped with RFT. I have never had so many flat tires in this past year on both cars in my entire life! I think run flats do puncture more easily. I live in the country side and it s a real pain having to replace tires so often. Luckily I got an insurance package on my second car so at least I don t have to pay the costs of replacement all the time. If you buy a BMW make sure you get the insurance package!! They don't always remember to offer it and I think it s because they know it will be paid off for sure!

Hi Gary,

Monday, September 9, 2013 by Gary

John,
The rear size should be 255/35R18 rather than 225/35R18. You can indeed minus size to 17" with size 225/45R17. This size fits both the front and rear 17X8 and 17X8.5" wheels and work well for winter use. Top choices would include the Michelin Xice Xi3 or Bridgestone Blizzak WS-70 for maximum snow and ice traction. Yes, it is recommended to continue to use TPMS sensors.

Steve,

If you not an aggressive driver and you are seeking a tire that maximizes ride comfort and tread wear over handling and steering response, the Michelin Defender in the H speed rating would indeed make sense as an appropriate choice. We do not sell spare tire kits, sorry. For the 1995 M3, are you looking for all-season tires or a summer-only performance tire?

I hear some people put the wider for better perfm but sometimes rubbing starts to happen.
Thursday, October 10, 2013 by Gary

Diego,

Generally speaking, summer tires have better traction in dry and wet, while all season tires have longer wear.

The PSS has better handling than the S04 Pole Position. Wider tires would give slightly better cornering grip.

When I check Michelin's web site, they recommend the Primacy HP or Pilot Sport AS/3 for my car, but all of those are non-RFT.

Tuesday, October 22, 2013 by Gary

Randy,

Non run flat tires work with no problem on the 2007 Z4 3.0 sport package and are a common way to go to find tires with longer wear and a softer, quieter ride. The Primacy HP would be softer and quieter than the AS03, while the A/S03 has better handling and grip.

I have a 2012 X5 sport with only 10,000 miles and the tires are completely worn out. I am not going to put run flats on again unless they warranty 50,000 miles. Can anyone suggest a tire for X5 fronts 275 40r20 and rears are 315 35r20.
Wednesday, November 6, 2013 by John

I have a 2011 BMW X3, tire rack lists two Michelin tires I am interested in. Primacy MXM4 in 245/50/R18 in two different load/speed ratings - 99V and 100H. My vehicle's OEMs are 100V. What is the differences between both of these tires in terms of ride quality, comfort, and handling? Are the sidewalls stiffer on the 99V than the 100H? Will the 100H degrade handling quality?

Any assistance would be greatly appreciated.
Wednesday, November 6, 2013 by Gary

John,

The V speed rated version of the tire will have slightly quicker steering response and a bit better handling, while the H will give a slightly softer ride.

I have a 2012 328i. One of my tires need replacing and I honestly want to rid myself of the non flat tires. Which tire would you suggest that I replace with and would it be ok to just replace one for now? Would this affect my vehicle in any way?
Thursday, December 12, 2013 by Gary

If replacing just one or two tires, you should match to the same brand and model of tires to avoid unstable handling and pulling problems.
Monday, December 16, 2013 by Andy

Great thread, Gary. I have a 2011 335i convertible with OEM 19" rims (Bridgestone Potenza RE 050A: 225/35R19 front,
255/30R19 rear) that I recently bought CPO. This is my first bmw and I've been surprised by the highway road noise and slightly rough ride. I'm trying to figure out how much to attribute to the run-flats vs the rims, and if I make a change, what direction I should go. Are 17s or 18s significantly quieter? Are non-run-flats quieter and smoother? Sure, the 19s look cool, but I'm not attached to them. Thanks!
Monday, December 16, 2013 by Gary

Andy,

Three things are working to make the ride stiffer : The tire size (shorter tires tend to be stiffer in general), the fact that these are summer performance tires, and that these are run flat tires. Changing any of these things will improve the ride as all three are contributing to the firmer ride to a similar degree.

Road noise is mostly a matter of the type of tire rather than the size and all tires tend to get louder as they wear.

Great post. I have 2011 328xi coupe, live in syracuse(snow capital) but moving to lexington, ky next summer, so still need to endure one full snow season. At 39,000 miles my OEM Contiprocontact SSR 225 45r17 have worn out and will need non-run flat tires. from thread above i have concluded my options as continental DWS, Bridgestone potenza re970AS and Michelin pilot a/s plus. I do prefer handling slightly over smooth ride. Which tires should i go with. Also, do i need new wheels/rims and new TPMS. Thanks
Tuesday, December 17, 2013 by Gary

You can install non run-flat tires on your current wheels and use the existing TPMS sensors with no problem.

Based on the conditions and your preferences, I would lean towards the Bridgestone RE970 A/S Pole Position as the tire to go with.

Gary, I bought a used 2002 Lexus SC 430 which when originally made came equipped with run flat tires (245/40R18) and no spare.. Stupid to admit that at the time I bought the car,I was unaware that because the car came with run flat tires, there was no spare... When I purchased the car, the tires had been switched to non run flats. I would like to (and one of my primary reason for purchasing)drive the car on long distanced cross country road trips. Needless to say, I'm afraid to do so w/o some type of spare/emergency tire situations. I'm considering purchasing the Bridgestone Potenza RE 960 Pole Position RFT Ultra High Performance All Season tires, but am becoming somewhat skiddished base on all the horror stories I am reading about run flat tires...What is your professional/general assessment about run flat tires (and this model tire in particular)? And, if I opt not to buy the rft, where can I find a conversion kit for a donut spare for my make/model/year car?
Friday, December 27, 2013 by cortes

Hi Gary, I was just told that my 328i BMW sport package that will be 1 year in 2 days need the four tires replaced, I took it to the dealer because noise in the front right. All tires 225/45R18. What brand would you recommend that I buy? I am a common driver, just need tires that last and a reliable car. Thanks a lot for your time!
Monday, December 30, 2013 by Gary

Top run flat all season tires in 225/45R18 would be the Continental Pro Contact SSR.

2011 328i with 20k miles on Continentail run flats. Very smooth drive and now it wore out and I would like to switch them to non-run-flats.
Michelin Pilot Super Sport A/S (all season) that you mentioned on the previous topic, Are they good and can me a smooth drive? I mean no noise while driving
and i am also willing to equip a spare tire and a wheel for a long journey, can you recommend me one

thanks

While I do not know of a temporary spare setup, I can recommend a smooth and quiet riding non run flat tire. What tire size do you use?
Sunday, January 5, 2014 by Angela

3 years ago I switched from staggered 18"RFT on my 2008 335xi for a quieter softer ride. I've replaced 2 sets of all season tires in this time. I'm considering going back to RFT for longer tire life. However, the pot holes in Chicago are brutal and I've already bent one rim. Is it wise to go back to RFT given their cost with the abundance of pot holes? Or should I opt for a winter and summer non-RFT set?
Monday, January 6, 2014 by Gary

Angela,

A dedicated set of winter tires would work better in snow and ice traction and would indeed be recommended over an all-season set.

I bought a 2011 335i drive in Sept of this year. It came with Contintental Pro SSr tires on it. I don't know if it's the run flat experience, but my car feels like it's never touching the pavement. It slides at 20-30 miles an hour and I have to release the gas to regain control. What do you recommend in an all season non run flat tire for my car? By the way I live in Illinois.
Thursday, January 9, 2014 by Gary

Tony,

The Sport A/S3 does not focus on a soft ride but instead on sporty handling and grip. If you're looking for a smooth and quiet riding non run flat tire I would consider the Bridgestone Serenity Plus and Continental Pure Contact.

Because I am a fan of Michellin

thanks
Tuesday, January 21, 2014 by Gary

Tony,

While the Primacy MXM4 does ride more softly than the Pilot A/S 3, it is still a bit stiffer than the Serenity Plus and the Continental Pure Contact which would be the softest of the three.

Hi Gary,
Time for new tires on my X5 and I am considering replacing the OEM Bridgestone Dueler 400 RFT’s with non-RFT’s, mainly due to poor tread wear and poor winter traction. (granted, some of the poor traction may be due to reduced tread depth and plentiful snow this year). I am wondering if the poor performance is due to the RFT tire itself. The Dueler and Pirelli Scorpion Verde each come in a RFT and non-RFT version. Has the Tire Rack ever performed a head to head test and directly compared RFT and non RFT version of the same model tire?
Thursday, February 20, 2014 by Gary

Peter,

There is not a difference in the tread pattern or tread compound between run flat and non-run flat versions of the same model of tire, so I would not expect a difference in wear or winter traction between them.
The most noticeable difference is that often times a run flat version of a tire rides a bit more stiffly than the non run flat version of the same tire.
Monday, March 10, 2014 by Matthew Snodgrass

My vote is against run-flats. They are SO expensive to replace, and it seems I've forever needing an alignment on my 535i. I'm going with non-run-flats next. Glad to see in this forum that you can do that.

Before closing a pending deal on a 2011 CPO BMW 35i X5, I need some more info on this RFT issue. I know the tire size will be 255/50R19 RFT's, but I don't yet know the brand.

My question is, will I be able to change from RTT's to non-RTF's if I feel compelled to, and will doing so affect my remaining "original" or CPO warranty?

Also, are there any vehicle control or safety issues that need to be considered?

Incidentally, the vehicle does have a spare tire!

Thanks

While I cannot speak for BMW's warranties, I can tell you that you may change all four tires to non run flat tires with no problems or safety issues.

By studying the thread above seems like best RFT option for 2011 328i Sedan base model to provide smoother ride and to replace the OEM Conti ProContact SSR R17/225/45 tires thst have 40000 miles on them are Bridgestone Potenza RE960 AS Pole Position RFTS.

Tires listed as back order on our site typically take sixty days or longer to get back into stock.

Thank you for replying.
That tells me people are buying this tire which is a good sign. Does this mean that if I place an order I will have to wait the full 60 days to receive the tires?I know this sounds like a dumb question but I just want to check as this has a bearing on my decision.

Friday, April 11, 2014 by Gary

Chris,

I can check on this for you. What tire size(s) are you using? Were you looking for summer performance tires or all-season tires?
Friday, April 11, 2014 by Trevor S.

I've had both good and bad experiences with run-flats. I have had them on our Mini Cooper, my 350z, and now my 2009 328i. The Continental ContiProContacts RFT has lasted 40k miles and they are great tires. I need to replace them and I always find myself in this dilemma. Run flats have definitely come in handy twice and allowed us to drive to a safe location to get the tires repaired. A lot of people mention the wear issue, which is really depended on the exact tire and the driving style of the owner. Either way, as a few have mentioned, you should weigh the pros/cons for non-RFT and RFT and determine what is most important to you. I will most likely buy RFT again, as they have been reliable and safe. The stiffer ride I actually prefer since I’m more for the sporty-aspect. It’s a more confident, stronger tire. But, also the non-RFT have their benefits.
Thursday, April 24, 2014 by Evan

Hi,
I have a 2012 328i RWD wagon with the sport package (staggered 17" wheels). I replaced the OEM summer RFTs with the Bridgestone 3G a/s RFTs 18mo ago and after 23k miles they are rough and are cupping. About what I had expected. I'll be doing a lot more driving in the next year and want less impact harshness so am thinking of getting the Continental DWS non-RFTs. The psi for the RFTs is 28/32 f/r. What psi would you use for the non-RFTs? Thanks!

I'm showing that BMW recommends 32psi front and 36psi rear on this setup.

Nice blog and Q/A. I have a 2009 335i sport package daily driver that I like to take out for aggressive road trips, and the OEM Potenza RTF need replacing. I live in NE OK where we get snow+ice several times during the winter.

I am paranoid about switching from the RFTs, but for the same money I could come close to geting separate sets of summer performance tires all-seasons for winter.

You'll probably recommend the Michelin PSS and Sport A/S plus -- but what horror stories have you heard from folks who switched from RFTs?
Tuesday, April 29, 2014 by Gary

David,

As long as you aren't mixing run flats with non run flat tires, there are no handling or safety issues.

Hi Gary - great posts, thank you.

I have a '09 328xi base model sedan (205/55R16) with OE RFTs and OE rims. I find the ride very stiff...feel every minor bump in the road. The RFT's are end-of-life and I am debating replacing them with new RFT's or with new non-RFT's. Three questions for you:

1) I have heard that putting non-RFT's on the OE rims may be a safety issue because the "bead will not fit properly". Will OE rims, which were presumably designed for RFT's, work just the same/be just as safe with non-RFT's?

2) has RFT technology improved over the last several years such that ride comfort between non-RFT's and RFT's is equivalent?; and

3) what would you recommend for a replacement RFT or a replacement non-RFT?

Thanks Gary. B
Thursday, May 8, 2014 by Gary

Brian,

1. There is no safety issue or bead problem with mounting non run flat tires on your factory wheels.

2. While the technology has improved, current runflat designs still tend to be stiffer than their non runflat counterparts with the possible exception of the new Bridgestone Driveguard which is supposed to be very soft riding for a run flat tire.

Top non run flat choices with emphasis on ride quality would include the Continental Pure Contact and Michelin Premier A/S.

Friday, May 16, 2014 by Gary

Among those tires, the best ride quality and wear will be with the Michelin Primacy MXM4 ZP. These are similar to the Continental in handling but have a quieter ride and should wear longer as well.

It is vital that you match to the exact same type, brand and model of tire if you are replacing three tires.

My wife got a 2008 328 convertible two years ago. We got it used from the dealer and of course it came with RFT’s. I hate them and have always hated them. Rough riding. Current tires are:
Front: Bridgestone Potenza RE 050A I, 225/40R18 88W
Back: Bridgestone Potenza RE 050A *, 225/35R18 90W

I hit a pothole and nicked a front tire and need to replace it but it is usable for now. My wife got a flat on the same side rear so now 2 tires need to be replaced. I want to go non-run flats. Likely this car will never be run in bad weather as I have heard the warnings about BMW rear wheel drive in slick conditions. We live in the mid atlantic megalopolis. City and suburban driving. Looking for something that is quiet and comfortable without trading off too much in performance. All weather might be good. What would you recommend?

I don't know how many I've hit this past year, yet with my old car and its non-RFTs I never had a problem. There are some advantages to RFTs though, so not sure if I should make a swap right away. My question is, are there ANY RFTs out there that are less likely to incur damage from potholes?

Gary,

I have a 2010 BMW 328xi with 225/45/17 squared. After the factory Continentals RFT’s wore out I tried a set of Nexen 5000 AS non-RFT. For the 1st 10,000 miles they were an excellent tire. They still handle great and wear has been excellent after a total of about 20,000, but the road noise has gotten ridiculously loud. What do you recommend as an all-around (Non RFT) good tire that is QUIET?

18"x 8" star-spoke light alloy wheels (style) 271 P245/50R20 all season run-flat tires. Can you suggest a brand for non run flat tires for this vehicle.
Tuesday, July 22, 2014 by Carl

I have a 2012 535i BMW sport sedan, live in Florida. Need to replace the tires which are the Pirelli P0 run flats, I have 225/35 R20 90Y on the front and two 255/30 R20 92Y on the rear. I am considering switching to non run flat tires, but would like to know what you recommend as the best choice. How would this affect the car's driving performance and feel. I know there is no spare but I have AAA and roadside assistance. Thanks
Wednesday, July 23, 2014 by Gary

Cynthia,

I'm not showing the 245/50R20 size as one that would fit the 2011 550i GT. If you meant 245/50R18, I like the Pirelli P7 All Season Plus and Hankook Ventus S1 Noble2 .

Wednesday, July 23, 2014 by Gary

Carl,

There are not many options in the 225/35R20 and 255/30R20 sizing setup, but the best non run flat among them is the Sumitomo HTRZ 3. These would have a softer ride than the OE tires but with a bit slower steering response than the OE run flat tires.

Hi Gary,
I have a 2012 BMW 535i with Sports package. (Front: 245/40ZR19 Rear: 275/35ZR19). I'm considering to switch to non-RFT. You had recommend the following two options to other folks on this thread:
1) Michelin Pilot Super Sport 2) Bridgestone Potenza RE970AS Pole Position.
I live in San Francisco bay area and my commute are mainly on highway. Do I need all season tires? Which model would you recommend?
Thanks,
David
Tuesday, July 29, 2014 by Gary

David,

If you are not driving in snow or freezing temperatures, you do not need an all season tire. Summer tires have better wet/dry grip, handling and steering response, while most all season tires will have a softer ride and longer wear.
Tuesday, July 29, 2014 by tony

I have a 2013 Toyota sienna awd with run flat tires. Would you please inform me whether or not a non run flat spare tire can be used in an emergency situation. If yes, what size of the non run flat spare tire can be used (my run flat tire size P235/55/RF18. Thank you very much
Tuesday, July 29, 2014 by Gary

Tony,

As long as the tire is the same size it can be used temporarily as a spare tire in an emergency situation.
Wednesday, July 30, 2014 by David

I just bought a used 2014 Infiniti Q50 (21k miles on the car) less than 4 weeks ago with RFTs. DUNLOP SPORT 5000 DSST CTT, 245/40/19. Tread is 7/32 left on the car. Today on my way to work I hit a pothole and blow one out. I'm considering ditching the RFTs for non RFTs. What's your thoughts? I've done a fair share of reading and have gathered the RFTs wear faster, are noisy, more expensive, bumpier and just down right awful. Is this true? Would it be worth me changing all 4 to non RFTs now and be done with it or replace the one bad RTF, then deal with replacing them all together down the road? I do a lot of driving and do have a spare.

Additionally, I using said spare but it's a 17inch rim vs. the other three wheels are 19inch. Is this a big no-no to drive with different size wheels?
Thursday, July 31, 2014 by Gary

David,

If you stick with a run flat design, you may want to consider the Bridgestone Driveguard for a run flat with longer wear and a smoother, quieter ride that is comparable to non run flat tires. Infiniti design the vehicle to be used with the spare tire size that it is equipped with from the factory so no worries there.

I'm purchasing a 2015 328 d. I have had RFT on my 2008 Toyota Sienna and have not had any problems with "buffeting" noise or course ride or short life. Should I expect to encounter all these issues with the 2015 328 d I've ordered???
Friday, August 1, 2014 by Gary

Bill,

I'm not sure exactly what size, brand and model of tires are coming with the 2015 328D as we have not seen one yet. Without knowing what tire, I cannot know what you can expect in regards to noise or tread wear.
Friday, August 1, 2014 by Cam

Gary,

I have a 2009 BMW 335i convertible with 245/45/17 on all 4. I bought the car used about six months ago with ContiProContact SSR in front and ContiProContact non-SSR in rear. After reading this thread it seems that my first issue is having RFTs and non-RFTs mixed.

I live in the southeast and will never be driving in snow. I do drive in a fair amount of rain.

Will you please recommend an RFT and non-RFT option that will handle well on wet and dry roads and that will achieve a smooth ride?

Thanks,
Cam
Sunday, August 3, 2014 by Mark

Hi Gary,
Thank you for your help on this forum. I have a 2012 BMW 740i with Pirelli P-Zero (Fr 245/45/19). Since I've owned the car I have disliked the run-flats and swore to replace them. Here I am at 26k miles and the fronts are looking pretty bald...
Reading your posts about run-flat improvements etc., I think I should be open minded to learn if there is a RFT tire I can love. My problems with the Pirellis are harsh ride, terrible wet grip and hopping, left-right, over road imperfections. Can you suggest the best all season RFT and non-RFT tires for me?

Thanks again, Mark.
Monday, August 4, 2014 by Gary

Mark,

If replacing two tires, your best option is to match to the exact same tire to avoid safety issues and problems with unstable handling.
Monday, August 4, 2014 by Gary

Cam,

Are you sure of the 245/45R17 sizing? Could you have 225/45R17 instead which would have been the correct size?
Friday, August 8, 2014 by Mark

Gary, Sorry for the confusion, I am replacing all tires. I'm leaning away from run-flats but wanted to learn more about the advancements in the market since the Pirelli P-Zeros hit the market.

Can you help me with my decision and suggest tires in both categories?

Thanks for your help,

Mark
Monday, August 25, 2014 by Paul H.

I have a 2009 mini cooper s clubman with conti 16" run flats. They need to be replaced again. I'm not so impressed with their short life, rough ride, road noise. Can you suggest a different tire? I need all season tires for the Midwest and would like them to handle well b/c I'm kind of hard on my car. I'm also wondering if the new bridgestone driveguards would disappoint? Thx.
Tuesday, September 9, 2014 by Gary

The Bridgestone Driveguard would be our top recommendation for a run flat tire for longest wear and best ride quality with low noise.

I have a 2012 Mini Countryman All 4 S.....I am very disappointed with the runflats and the ride. Can you recommend a non runflat tire for me!
Wednesday, September 17, 2014 by Gary

Anthony,

You can use 205/50R17 as a spare for any wheel position.
Saturday, September 20, 2014 by Craig

I have a 2014 BMW X5 diesel with the 20" staggered Pirelli RFT's. Over some roads, it seems like you can feel every piece of rock in the asphalt, and it is definitely road surface feedback not tire balance. Is this the harshness people complain about in RFT's? If so, they need to go and can you recommend a good replacement in an all season or summer tire. Thanks in advance.
Monday, September 22, 2014 by Gary

Craig,

Going to a non run flat all season tire like the Continental Extreme Contact DWS would indeed soften up the ride on your 2014 X5.

Monday, September 29, 2014 by Ron

I had to replace a rear RFT on my 2011 335i Coupe. I decided after long thought and forums to go to Non RFT. It took 4 days to get ordered tires and I got Continental Contisport on my staggered tires. I now have the best ride ever and noise is near gone. I have no spare yet and really ponder getting one, for how often have you really used a spare? Have fun and know RFTs are not a great ride and only save car makers a little money and sacrifice a great ride experience.

What alternate tire options are there? How about a 235/60 R17 tire as suggested by a local store?
Sunday, October 26, 2014 by Don G

GAry,
I am about to purchase a 2014 BMW 3.28iX Luxury Trim.
The current tires are Conti Run Flats. Dealer is offering protection package for over $1K. My thought is to not purchase the package but to use the money to switch the tires to non Run Flats and purchase the Conti Mobile Repair Kit offered by Tire Rack. My concern is that the car seems to run a bit rough at speeds over 45 mph. There is a resonance that appears as well. Will running non Run Flats affect the performance of the vehicle? The car would not be driven hard. It currently has about 5K miles on it. Your thoughts?
Tuesday, October 28, 2014 by Gary

Lee,

The following all season run flat tires are made in 245/55R17 : Bridgestone Dueler HL400 RFT, Pirelli P7A/S RFT.

Tuesday, October 28, 2014 by Gary

Don,

Many non run flat tires are available that should soften up the ride, but "running rough above 45MPH" sounds like a simple tire balancing problem to me.

2009 BMW 750i. Last year pot holes took a toll on my rims and run flat snows and I need to replace wheels & tirees What would be your suggestion for rim size and snow ties. I would prefer to stay away from RFT if possible as they are such a hassle.

Anyways that car is terrible in the snow is there an all reason tire for my car the front and back tires are 2 different sizes , would I also need to get new rims to fit all season tires?

Hi,
I have a 2013 BMW 535 Gran Turismo with 245/45R19 runflats on front, and 275/40R19 runflats on rear. I am not an aggressive driver and mostly highway miles and have replaced all four twice at 17-20k miles and two more due to flats that can't be repaired on RF's. This is becoming an outrageous expense (and unfortunately purchased via BMW dealer $$$). I'm inclined to ditch the RF's due to they can't be patched and I need much better wearing tires. Advice appreciated before I order.

I have a 2007 BMW 328ix that I've driven for 5 yrs and approx 40k miles. I've always been disappointed with my Turanza RFTs (225-45-R17) due to high road noise, poor snow handling (I live in Denver) and damaging pot hole collisions (had to replace a cracked rim which cost $475). I'm considering going non RFT to hopefully improve all of the above. And getting a mobility kit and hoping that I don't regret not having a spare in an emergency. Any recommendations would be greatly appreciated.

Hi Gary, Thank you for this website and all your incredibly wise information! I just purchased a 2011 328i Convertible yesterday from the dealer in scottsdale, az, and had never heard of RFT tires! My last bmw (2001)was 325Ci and drove like dream! This one is so harsh and has that infamous run flat noise when on the highway. What tires do recommend? The Michelin Pilot Super sport or the Continental Extreme Contact DWS? After reading your letters, I will be replacing all 4 tires with the non run ones! Please advise.

cracked & replaced 8 rims in less than 2 yrs(never had this in any other car.) Friend of mine (a mechanic) suggested moving from 19in to 18in rims but keep run flats. Any suggestions on strong rims? would I be better also going without run flats? love car hate rims!!

My 2011 BMW 550 runflats had at least one tire every 2-4 months go out since I bought it. This winter was the worst. I replace 4 tires over a 18 week period. Every time I hit a pot hole I prayed I didn't blow out the tire...

I've had it, I'm trading it in for a Q7 with normal tires. Sucks because the car is awesome otherwise.
Friday, March 13, 2015 by Gary

Dave,

Going to 18" wheels will allow you to use a slightly taller tire which may help a bit in durability. However, if you are cracking 19" wheels with your current driving conditions, moving to 18" will not likely make enough difference.

Hi Gary,

Fantastic blog and community support. Awesome job, mate!

After researching a bit - I have narrowed my options down to a couple of alternatives. Here is my scenario:

Problem:
-----------------------
I have a 2008 BMW 335i Convertible. My front left tire (225/40r18) is early bald in the inner side, probably due to an alignment issue. My left rear tire (255/35/r18) has a nail. Both right side tires are good and have good threads little more than 1 year old. All four tries are Bridegstone Potenza RE050 RFT, Y rated summer tire. Also note that I live in Seattle and endure 9 months of rain.

Option 1 - do the minimum:
---------------------------
Change the two affected tires with the same RE050 RFT. Estimated cost $735.00

Option 2 - replace all with non-RFT:
------------------------------------
Replace all four with Bridgestone Potenza 960AS Pole Position NON-RFT. Estimated cost ~$851.00 for all four non-RFTs.

Option 3 - change two with different kind:
-------------------------------------------
Change the Front left and back left RE050 RFT with Potenza 960AS RFTs. I know mixing RFT and non-RFT is not recommended. How about mixing two different series of RFTs from the same manufacturer? If recommended- this will be the cheapest option.

Please let me know your take on this or suggest a fourth alternative if you prefer. Thanks for taking time.

Hi, I have a BMW X-1 with 225/50 R 17 Run flat tires, and am thinking of switching to regular tires. But I have been reading that (supposedly) the suspension is "tuned" specially for run flat tires, and that switching to regular tires will cause handling problems. I am wondering whether this is something special related to the X-1, or if it is just propaganda... Will the Bridgestone Turanza Serenity Plus or the Michelin Pilot MXM4 offer good or even excellent handling for a (primarily) highway driver?
Tuesday, March 17, 2015 by Gary

Richard,

I have no evidence to support the notion that installing non runflat tires on the this car will cause handling problems.

Our customer feedback and experience with the Bridgestone Turanza Serenity Plus has been much better than with the Michelin Pilot MXM4.
Tuesday, March 17, 2015 by Gary

Kalrashi,

Avoid mixing tires, even different models within the same brand. The RE050 is very different from the RE960 A/S and should definitely not be mixed. Stick with a solution that ends up with all four tires matching. For all-season run flat tires, we've had particularly good experience and feedback with the Bridgestone Driveguard as well as the Bridgestone Potenza RE960 A/S RFT.

Hi My wife loves her 2006 X3 however I'm having a problem loving the run flat tires inshort can I safely put regular tires on her car and go to sleep at night without tossing and turning worried if I made a wise decision. tires on car now 235/55 RF17
Monday, March 23, 2015 by Gary

Bill,

Yes, you can use non run flat tires on this vehicle with no problem.
Tuesday, March 24, 2015 by AC

Some people claim that the extra weight of RFT's decrease gas mileage and put extra wear on your brakes. Is any of that true?
Wednesday, March 25, 2015 by Gary

AC,

We have not found that such a small difference in weight between most models of tires has a noticeable effect on brake wear or fuel mileage.
Friday, March 27, 2015 by Christine

Hi Gary,

We have a 2010 x5 xdrive35d and we are coming to the end of the RFlats that came with the car. My husband got a quote for 4 more (Pirellis I believe) from the dealer @ $1400 - which I think is just a little nuts for tires that will only last 30K miles. I want to go for a nonRF tire - can you recommend the best one for us? We live in Florida (so snow is and probably never will be an issue) and I generally have felt like I'm on a safari when I drive my car on our local brick roads. I've seen Michelin in this thread a lot - but haven't been able to locate my model so I apologize if you're repeating information! Any recommendation would be much appreciated!!
Tuesday, March 31, 2015 by Gary

Christine,

What size(s) of tires are you using on the X5?
Friday, April 3, 2015 by Rick

Good article, very informative. I'm seriously thinking of ditching the run-flats on my Infiniti Q50. The ride is bumpy and very, very noisy. (Dunlops.) Can you suggest a good, all weather non run-flat alternative? Would like to have a smoother, much quieter ride. Thx
Friday, April 3, 2015 by Sam

Hi Gary,
I have a 2011 BMW 335i with M Sport package, Pirelli P Zero Front 225/35-19 and Rear 255/30-19. I am tired of the terrible ride I've been having while paying over $3000 to change the tires and wheels in the last 4 yrs. Yesterday, i got another flat in my left rear tire and i think this is a good time to finally switch to non-RFT. Can you recommend any good non-RFT that match my tire size?
Also, I am in Maryland and with all the snow this year, I think it might be better for me to get All-season instead of the current summer tires. Thanks.
Friday, April 3, 2015 by Barbara

I have a 2009 128i and want to change to non-RF tires. I live in Hawaii and on a steep hill. Currently have 205/55/R16. What do you recommend for replacement, and should get wider tires to accommodate the hill?
Monday, April 6, 2015 by Gary

Rick,

What size(s) of tires are you using?
Monday, April 6, 2015 by Gary

Sam,

Unfortunately we have no all season tires in those sizes, but top summer non run flat tires with emphasis on ride quality would include thee Continental Extreme Contact DW and Hankook Ventus V12 EVO2.
Monday, April 6, 2015 by Gary

Barbara,

If you'd like wider tires, you can use 225/50R16 with no problem. I'm not sure what is meant by "accommodate the hill", but top tires for wet traction in 225/50R16 would include the Continental DW and BFGoodrich Sport Comp2.
Tuesday, April 7, 2015 by Mike

Hey Gary,
I have a 2008 328i coupe base 17" tire.

I want to switch to non run flat tires. Which tires would you recommend?

Replacing the tires will not affect the electronics at all? (TPMS ???)

Also, if I go to non run flats will they fit on the original BMW rims?
Tuesday, April 7, 2015 by Rick

Tire size 245/40r19, all season. Thanks!
Tuesday, April 7, 2015 by Rick

Size: 245/40R19. Thx
Tuesday, April 7, 2015 by Diane

Hi Gary,
I have a 2010 BMW Z4 with Bridgestoe RE050A run-flat tires, front 225/35 ZR 19 and rear 255/30 ZR 19. I'm thinking to replace the run-flat tires to non run-flat tires for my Z4. Can you recommend couple of choices for me. I live in California. Thanks!!
Tuesday, April 7, 2015 by Gary

Rick

Top choices for all-season non run flat tire sin 245/40R19 would include the Pirelli P7 A/S Plus and Continental Extreme Contact DWS.
Tuesday, April 7, 2015 by Gary

Mike,

I can check on this for you. What tire size(s) do you have? Are you looking for all season tires?
Tuesday, April 7, 2015 by Gary

Diane,

Top tire choices in 225/35R19 and 255/30R19 would include the Continental Extreme Contact DW and the Michelin Pilot Super Sport.

http://www.tirerack.com/tires/index.jsp?affiliate=FH8
Tuesday, April 7, 2015 by Mike

Hey Gary,

I am looking for summer tires. Read a bit and seems like you recommend the Michilin Pilot Super Sport.

The size is 225/45/17.

What about the stock bmw rims, will they work with the new non runflats?

What about the TPMS, no problems with the new non runflats?
Wednesday, April 8, 2015 by Rick

Thanks for your time and consideration! Very helpful indeed.
Wednesday, April 8, 2015 by Gary

Mike,

You can indeed use non run flat tires on the same wheels with the same TPMS sensors with no problems at all.
Wednesday, April 8, 2015 by Diane

Thanks Gary! Really appreciated!
Wednesday, April 8, 2015 by Hugh

hi Gary, I am looking to replace the RFT for my 2012 X5 as they are bare after 20K miles already. would you recommend anything for the front and back tires (275/40R20-106W, 315/35R20-110W)? will non-RFT be a better option?
Thursday, April 9, 2015 by Diane

Hi Gary,
Is Continental Extreme Contact DW going to be discontinued?
Thursday, April 9, 2015 by Gary

Hugh,

If you're looking for the longest wearing tires in these sizes, I would suggest the Continental Extreme Contact DWS which is a non run flat tire.
Thursday, April 9, 2015 by Gary

Diane,

The Continental Extreme Contact DW is a current production tire and I can see no signs of it being discontinued anytime soon.
Monday, April 13, 2015 by Eddie

hello, I bought a 2006 Corvette with Hankook 245/40 ZR 18. i hit a pothole and the tire pressure warning came on and said tire out of air pressure. there is a bulge in the side wall. i know i can't fix it but my question is do i need to replace both of the fronts? I don't drive aggressively can you recommend cheaper non run flat brand of tires? i think the Hankooks have 12-15k miles on them and they look a bit worn. thanks so much
Tuesday, April 14, 2015 by Mitch

Gary,
I have a 2013 BMW X3 presently with with 245/50/18 RFT Perelli P7 Cinturato All Season. It has 30,000 miles and has cupped or "lumpy" tread.
questions;
1 I live in NC and we deal with 3 - 5 days of light snow a year.
2 The tires are loud

The warranty guys have said it will mess up the transfer casing to switch to non-run flats.

I think I want to go with Non run flats that are safe, quiet and handle well.
What do you recommend?
Tuesday, April 14, 2015 by Gary

Mitch,

As long as all four tires on the matching, there is no effect on the transfer case. Top choices for non run flat tires for what you're looking for would include the Bridgestone Turanza Serenity Plus, and the Hankook Ventus S1 Noble2.
Tuesday, April 14, 2015 by Gary

Eddie,

Yes, we recommend against mixing different tires. It is best to have four matching tires.
Wednesday, April 15, 2015 by Rick (again)

In terms of ride comfort and noise level, what differences can I expect between the run-flat Bridgestone DriveGuard vs. the non-run-flat Pirelli P7? Thanx
Wednesday, April 15, 2015 by Gary

Rick,

The Driveguard is smoother and quieter, with better wet and snow traction and longer wear the the old Pirelli P7. The newer Pirelli P7 A/S Plus would be just as good as the Driveguard, but is not a run flat tire.
Friday, April 17, 2015 by Ganesh

I am looking for all-season RFT for my X3 x28i for safe driving in snow. Can you suggest the most economical option?
Friday, April 17, 2015 by Gary

Ganesh,

I can check on this for you. What tire size are you using?
Sunday, April 19, 2015 by MitchJ

Gary (and others)
I am ditching the Pierlli Cinturato RF 225/45 R18 off of our new 2015 X1 M Sport that has 5600 miles; the RFT are so unreasonable and takes all the joy of getting behind the wheel. Did my research and going toward the non-RFT Pierlli Cinturato P7 All Season Touring tire since it has nearly the same specifications as the RF. My choice is the 91V (treadware 500) or the 95V (threadware 700) rating tire and perhaps should go toward the 95V rating since the BMW does have the stiffer, sport suspension. Wanted to minimize any changes to handling and performance. Is my thinking correct or do you have any changes/recommendations?
Monday, April 20, 2015 by Gary

Mitch,

The non RFT version of the Pirelli Cinturato P7 All Season Plus tire in 225/45R18 has a UTQG of 700. There is no other non run flat version in this size. The run flat Cinturato P7 All Season has a UTQG of 500. Either tire will work fine, but the non run flat version will give you a softer ride and longer wear.
Tuesday, April 21, 2015 by MitchJ

Gary,
Thank you for your comments. My wife and I decided to remove the RFT Pirelli Cinturato P7 All Season Plus tire 225/45R18 91V rating for the non-RF version of the Pirelli P7 because it is just to hard a tire (at recommended pressures) and an extremely harsh ride. I am opting for the 95V rated non-RF version with the reasoning that it is better suited to the driving dynamics of the BMW X1 MSport suspension. It should still give a softer ride although it is not the original 91V RFT OEM with the car. **Can you correct me if this reasoning is wrong? I see that I can go with the Ultra Performance choice of tires as another option. The UTQG of 700 is not our primary concern but we are looking for a radical change in driving comfort without compromising the safety, handling, and performance of the car.
Tuesday, April 21, 2015 by Gary

MitchJ,

Yes, the non run flat Pirelli Cinturato P7 All Season Plus will indeed have a softer ride and most prefer this tire over the OEM runflat tires.

Tuesday, April 28, 2015 by Nick

have a 2008 bmw 128i convertable w/ sport pkg. current tire s front 205/50R17, rear 225/45R17 should i go to non runflat tires for more comfortable ride? what tires would you recommend? will be driven spring summer fall. Can i go wider on front or back?
Tuesday, April 28, 2015 by Gary

Nick,

What tire size(s) are you using?
Tuesday, April 28, 2015 by Gary

Nick,

You can use up to 225/45R17 up front and up to 245/40R17 rear. Top summer non run flat choices for ride quality would be the Contintental Extreme Contact DW.
Tuesday, April 28, 2015 by Ed

I have a set of RE050As in 225/40/R18 on a 2011 335i that are getting close to time. My car has the staggered setup with a different size on the rear, and the rears have TONS of tread left. Wondering if I could go to non RFT on the from while keeping the (almost $400 each) RFT on the rear until they wear out. Was thinking of the Conti DW or the Pilot Super Sport, both are highly rated by performance enthusiasts.
Wednesday, April 29, 2015 by Gary

Ed,

Avoid mixing tires, even different models within the same brand. It is especially undesirable to mix run flat and non run flat tires.
Friday, May 1, 2015 by ed

will be changing all tires from run flat to non run flat 225/45/17 best for tire for comfort and quiet 2011 328i
Friday, May 1, 2015 by Gary

Ed,

Top choices for comfort and quiet in a non run flat tire in 225/45R17 would include the Continental Pure Contact and Pirelli P7 A/S Plus.
Saturday, May 2, 2015 by Rick

Wanted to pass on my experience to you and your readers.

I have an Infiniti Q50 with 19" tires. The ride, comfort, and noise level was atrocious on the Dunlop run-flat OEMs. I replaced them with Bridgestone DriveGuard. Great improvement all around. However, based on your suggestion, I decided to exchange the DriveGuards for Pirelli P7+ non-run flats and the noise and ride comfort improved even more though only slightly over the Bridgestone run-flats. My main reason for choosing Pirelli was for their snow/ice performance which, according to the Tirerack site, provides for a safer ride.

Overall, the Bridgestone DriveGuard and the Pirelli non run-flats compared favorably in noise level and performance, though I give the Pirellis a slight nod. Had the DriveGuards been installed originally, I probably would have been kept them and would not have considered swapping them out.

But definitely, the Dunlops run flats were a bad choice by Infiniti. It really didn't do the Q50 justice.
Monday, May 4, 2015 by Steve F

Gary,

I have a challenging one here. I drive a 2012 550i xdrive with the M package and 19 inch wheels (think its Front tires 245/40/19 and rear 275/35/19). I went with the Dinan S2 as I like to drive somewhat aggressively, although not on a track.

My challenge is that I live in NJ where the roads aren't very good (potholes) and we obviously get a bit of snow and cold weather. Noise and smoothness aren't as important to me.

What would you suggest (RFT or regular tires) that will be a) handle well, are all weather and will hold up against the crappy road here? Will sticking with RFTs provide better performance and resistance to road hazards? I just split one of the RFTs and it was just about time to replace all of them so figured I should consider all my options now.

Thanks!
Tuesday, May 5, 2015 by Gary

Steve,

We haven't found that any particular tires are more resistant to pothole damage (either RFT or non RFT), but top choices for all season tires in 245/40R19 and 275/35R19 would include the Continental Extreme Contact DWS and Goodyear F1 Asymmetric All-Season.
Wednesday, May 20, 2015 by Leigh

Hi Gary. What a blessing to find this blog!
I just bought a 2915 BMW X3 Sdrive28i. I drive 800 mile trips in rural areas frequently, so thinking I should ditch the RFT and go NON and carry a spare, as the small towns within 50 miles may not have tire stores or carry what I have. Is this sound reasoning? If so, what do u suggest? Mostly Az, NM and Tx so no snow. But rural 2 lane roads.
And can spare be small, or full size needed?
Thanks!
Thanks for any input!
Wednesday, May 20, 2015 by Leigh

I forgot to say that it has Goodyear eagle LS2
245/45R19 now. R these ok quality? If not I might as well exchange them all now, since I drive in places with help few and far between, traveling alone except for dogs. They won't help change tired. :)
Thursday, May 21, 2015 by Gary

Leigh,

While the Goodyear Eagle LS2 is a good quality tire, we can recommend better tires in 245/45R19. I would recommend the Continental Extreme Contact DWS and Continental Pure Contact.
Thursday, May 28, 2015 by Eric

Gary,

I have a 2011 BMW 750i with RFT's and 245/40-20 front and 275/35-20 rear. I am considering going with the non RFT's. What suggestions do you have for So. CA. driving? Looking for something mainly that are comfortable and quiet, and decent longevity couldn't hurt!
Thursday, May 28, 2015 by Tony

2014 BMW 328i 6000 miles and two flats. Ready to go to non-runflats.

Current tires front and back are Michellin Primacy MXM4 ZP 225/50R17 94V. Suggestions for replacement? Thanks
Friday, May 29, 2015 by Gary

Eric,

Top summer tires in these sizes for a quieter ride and comfortable ride would include the Continental Extreme Contact DWS and Bridgestone Potenza S04 Pole Position.
Friday, May 29, 2015 by Gary

Tony,

Top choices for non run flat all-season tires in 225/50R17 would include the Pirelli Cinturato P7 A/S Plus and Continental Extreme Contact DWS06 .
Saturday, May 30, 2015 by Eric

Gary,

"Top summer tires in these sizes for a quieter ride and comfortable ride would include the Continental Extreme Contact DWS and Bridgestone Potenza S04 Pole Position."

Any reason why the DWS and not DW on my car? What are the main differences other than snow ability on DWS?
Wednesday, June 3, 2015 by Gary

Eric,

That was indeed a typo, good catch. It is the DW that is the summer tire that I would recommend along with the S04 Pole Position.
Thursday, June 11, 2015 by Eric

Gary,

What about the Hankook Ventus v12 evo tire for my car? I have also heard some good things about it.
Thursday, June 11, 2015 by Brett

Gary - New 335i w/ M Sport package and 18" staggered set-up with Potenza S001 RFTs...and the ride is beyond rough and jarring. Would switching to non RFTs really make that much difference, and if so, what would you recommmend? Thanks!
Thursday, June 11, 2015 by Gary

Brett,

The right tires can make a large difference in ride quality. There are softer riding run flat tires such as the Bridgestone Driveguard that would soften up the ride quite a bit. If you go to a non run flat, checkout the Continental Extreme Contact DWS 06.
Thursday, June 11, 2015 by Gary

Eric,

The Ventus V12 Evo is an older tire but we have had pretty good experience and feedback with the newer version called the V12 Evo2.
Thursday, June 11, 2015 by Asif

Hi. Great site to get info.
I have some questions. I have a bmw x5 e70 from 2012 with 30d m-sport. I have right now rft tires: front 275/40/20 and rear 315/35/20. I bought the car 5months ago and it had uneven wear on front (mainly outer edges). But i havnt experienced any pull or unbalance. Im planning to switch to normal tires and wondering if i need to align my wheels on the front?? I dont want my new tires to wear down fast on the edges. Im also wondering if i can have bigger or smaller tires on same rims, for example 305 instead of 315 on 20 rims.
Thanks alot for your help.
Thursday, June 11, 2015 by Will

Gary-thanks for all the valuable information. I have a 2012 BMW X5 35d with run flat tires and would like to replace them with non run flat tires. I live in Los Angeles. Thank you.
Monday, June 15, 2015 by Gary

Will,

What tire size are you using?
Monday, June 15, 2015 by Gary

Asif,

I know of no alternate sizing, but if you are getting irregular wear then I would indeed suggest that you have your alignment checked.
Monday, June 22, 2015 by Leland

I have a 2013 BMW 535i MSport. I understand the benefits of RFT but the noise and ride quality are so substandard. I'm working through the RFT v Non-RFT issue. I think you said in an earlier message you have a similar car with Dinan S2. Do you run RFT? What do you recommend for my car? BTW very good information on the blog

2007 335i 225-45-17 rft no sport package want to replace all four with non run flat , want soft ,quiet ride,. .. looking at Michelin premier or mxv4 would appreciate your input on any that might be even better choice than these.
Thursday, June 25, 2015 by Gary

Ed,

The Michelin Premier replaced the older MXV4 and would be an outstanding choice as a replacement non run flat grand touring all-season tire. More info can be found in my blog :

Saturday, June 27, 2015 by Gary R.

Gary,

I have a 2011 328i xdrive with 19k miles. Front tire needs to be replaced. Considering switch to non RFT, since, I've been told, I will need to change all 4 tires due to the xdrive and the need to have all tires at the same tread depth. Thoughts? What should be the decision factors?
Monday, June 29, 2015 by Gary

Gary R. ,

Avoid mixing tires, even different models within the same brand. It is especially undesirable to mix run flat and non run flat tires. Replacement tires of the same brand and model should be within 4/32nds tread depth of each other for optimal performance and installed on the rear axle.
Monday, July 6, 2015 by Chris

Gary,

I have a 2012 X5 30D with 20" staggered wheels. What do you think of the Toyo ST II tires as an alternative to the Bridgestone run flats? I need an all season tire for winters in Maryland.
Tuesday, July 7, 2015 by Gary

Chris,

While I'm not familiar with the Toyo ST II tire, we have had very good experience and feedback with the Continental Extreme Contact DWS in those sizes.
Sunday, July 12, 2015 by Gordon

Gary,
I have a 2013 135i with just under 23,000 miles that needs new tires. The originals are Bridgestone Protenza 215/40 R18 front and 245/35 R18 rear. This seems like rapid wear to me and surprisingly, the bigger rears are wearing faster. I'd appreciate your suggestions as to run flat or non RF that would give better wear. A softer ride if handling isn't sacrificed would also be welcome. Thanks.
Tuesday, July 14, 2015 by Gary

Gordon.

The wear you experienced is pretty typical for a summer performance tire. You can move to an all-season tire to get longer wear, but there is will be a sacrifice in handling and steering response. If you decide to go that route, I'd suggest the Michelin Pilot Sport A/S 3
Tuesday, July 21, 2015 by bruce

I have a 2013 BMW X3 with Pirelli Cinturato P7 245/50 R18 run flat tires and only 25,000 miles. . This car handles like a wet noodle, wanders all over the road, pulls left, pulls right and there is a vibration at speeds over 60. I also see lots of cracks in the bottom of the tread. Are the RFT the problem ? What do you suggest for a non-RFT ?
Wednesday, July 22, 2015 by KUMAR

Hi Gary,

I am on due for replacing the Continental Contiprocontact SSR RFT'that initially came with my 2011 328i x drive. I was looking for suggestions of replacing them with Non RFT's. Here are the Options that i am currently looking at Continental ExtremeContact DSW/Continental ExtremeContact DSW06/Continental PureContact with EcoPlus Technology. All the 3 that are mentioned are All Season tires. So can you please provide your suggestion on the same.
Wednesday, July 22, 2015 by Gary

Kumar,

Are you looking for a tire with the softest ride or more of a sport tire with good handling and quick steering response?
Thursday, July 23, 2015 by KUMAR

Hi Gary,

I am looking for tires with smoother ride and i have Sedan with Sport package with 225-45-17. So i need your suggestions on which tire would be the best suitable non RFT's. I am also looking for a tire which would give me better mpg as well, as i roughly get around 300-320 miles for the full tank on my ContiProContact SSR's which are RFT's.
Thursday, July 23, 2015 by KUMAR

Hi Gary,

I was wondering what would be the difference between Grand Touring All Season and Ultra High Performance All Season. I am looking for a tire with softer ride and good handling capability in Snow, Wet and Dry conditions. I roughly get around 300-320 miles for the full tank currently, so i am considering the EcoPlus tires for an improved Mileage. I currently have the ContiProContact SSR's of 225-45-17 on my 2011 328i xdrive, so any suggestions on which would be the best suitable tire for my needs would be greatly appreciated.
Monday, July 27, 2015 by Gary

Kumar,

Generally speaking, Grand Touring All Season tires will have a softer ride compared to Ultra High Performance All Season tires. The Bridgestone Driveguard would have the best ride and all season traction among run flat tires in 225/45R17.

2012 BMW X5 35d factory wheels are 19" would like to upgrade to 21" wheels with an Michelin all season tires and have the speedometer re-calibrated.
Will this set up fit and work with out tearing something up?
Also your thoughts on inflating tires with nitrogen..

Thank you,

Mark

Mark,

We know of no all-season tires available in a 21" size that would fit the 2012 X5, sorry. Check out more about inflating tires with Nitrogen here :

Bruce,

We have not found that run flat tires are more prone to this condition. Top non run flat all season tires in 245/50R18 would include the Kumho Ecsta 4X II and Yokohama Advan Sport A/S.

I have a 2014 335i Sport Line. I went in for servicing and they mentioned to me that rear tires thread is almost gone and i need to change. Two rear tires plus alignment will cost about 700+ bucks. And i am just about to reach 10K miles on my lease. Not sure how to proceed as i don't have much experience with this. Not sure switching to non RFT will redcuce my overall costs or sticking with new RFT's would be better. Any suggestions please.

Dheeraj,

If just replacing two tires, we recommend that you match to the exact same brand and model of tires. Keep in mind that you may not need a wheel alignment on a 2014 model vehicle unless unusual tire wear has been found.

I just bought a 2012 BMW X1 xDrive28i with optional 18" rims and want to get winter tires that are non run flats on 17 inch wheels. Is that feasible, and any suggestions on tire selection? And this is a stupid question, but will all 225/50/17 tires fit all 17 inch rims?

Trish,

Yes, you can indeed use 17" wheels with 225/50R17 winter tires on the 2012 BMW X1 with no problem. Top non run flat winter tires would include the Bridgestone Blizzak WS80 and Michelin Xice Xi3.

I have a 2013 BMW X3 I just replaced the Pirelli Cinturato P7 245/50 R18 run flat tires at 25,000 miles.
The car now has Michelin Primacy MXM4 - NON-RunFlat . WOW, what a difference ... my car finally handles like a BMW is supposed to! Thanks Michelin!

I have a 2012 mini cooper S and I have to deal with terrible roads in Boston. Can you recommend a better tire that the miserable ones that came with the car? They are run flats and I have already had to replace some of them. I like to drive fast but the roads in New England are bad.

Nadia,

What tire size are you running? Are you looking to stick with run flat tires or replace all four with non run flat tires?

The additional 900 lbs in curb weight of my 2011 BMW 335 GT xi over the sedan make the entire run flat situation unbearable. I've replaced over eight tires and rims in 70k miles . What are my best options for normal tires? I have 19 inch models.

Harry,

Are you looking for summer tires or all-season tires? What 19" size(s) are you using?

I'm running run-flats on my X5, 4.8i. They are performance summer tires, with 315 in the back and 275 in the front (20"rims). SO far, no regrets. I've always run with non-run-flats, but can't spot the difference.

Since X5 doesn't have a doughnut, I'd rather have the run-flats.
