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

Friday, August 19, 2011 by Gary Stanley

Many 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

Friday, December 23, 2011 by Bert:: 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.
Sunday, January 22, 2012 by Tess:: 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!
Friday, February 17, 2012 by Chris Kittleson:: 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.
Wednesday, March 14, 2012 by John Sponza:: 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.
Saturday, March 17, 2012 by Peter:: 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
Tuesday, May 8, 2012 by Tim:: 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.
Thursday, August 9, 2012 by Andre:: 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.
Friday, August 10, 2012 by Mike:: 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
Sunday, August 12, 2012 by Raul:: 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
Tuesday, August 14, 2012 by Mike:: 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

Sunday, August 19, 2012 by NAOUFAL:: 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.
Friday, September 14, 2012 by Anil:: Gary
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?

Have been reading your comments and

that would ride smooth, safe in wet

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

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

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.

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 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.

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 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.

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?

i usually get the tire insurance but on this lease they raised it to $1,700.

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.

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.

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)

Wednesday, December 5, 2012 by tony:: 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.
Saturday, December 8, 2012 by Tarun M:: 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.

Monday, December 24, 2012 by Kevin:: 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.
Friday, December 28, 2012 by Manish Patel:: 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.
Saturday, January 12, 2013 by Stef:: 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?

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:: Connie,

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.

Tuesday, January 22, 2013 by Ping:: 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.

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:: Susan,

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.

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.

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:: Eddie,

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.

Thursday, March 21, 2013 by Sean:: 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.

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.

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.

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.

Saturday, June 8, 2013 by Rob:: 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.
