Run-Flat to Non-Run-Flat

Whether you own a MINI Cooper S, or a BMW X5, a very common concern among our customers is run-flat tires. A lot of vehicles that come equipped with run flats do so because they are more compact and lack the space for a spare tire. Run-flats are designed to act as a spare tire and run for 50 miles at 50 miles per hour after you have had a puncture. But they can sometimes be uncomfortable to drive on because of their stiffer sidewall.

Many of our customers want to switch out of run-flat tires...and it's OK! Non-run-flat tires give a smoother, more comfortable ride to your vehicle. The one thing you need to be conscious of, however, is that you may not have a spare tire. But that's an easy fix, too! A ContiComfortKit is the perfect way to ease your mind if you're switching out of your run-flats. The ContiComfortKit is a compact air compressor and a tire sealant. You can patch a small hole in your tire, and use the compressor to bring it back up to the proper air pressure. After the repair, your tire can be driven up to 125 miles at 50 miles per hour, giving you extended mobility to get home or to a repair facility.

Switching out of your run-flats is a simple process.You don't need any special equipment and you can use the same wheels you already have. You also don't need to worry about your TPMS sensors, those will work just fine with your non-run-flat tires.

So, to confirm, I could use the ContiComforKit on stock 128i wheels and TPMS and not damage the TPMS sensors? Thank you

Eric, Thank you for your question. The sealant in the kit can permanently damage the TPMS sensors. The comment above was in response to questions we have had questioning if the sensors would work correctly with non-runflat tires. If you have to use the tire sealant you will likely have to replace the TPMS sensor. We apologize for any confusion.

I wanna switch out the 17" run flats on my mini clubman to the original 16" non-run-flat tires that came with the car. Can I do that with no problems? I have AAA so if I got a flat, I would just call them. Thanks!

Can you give me average mileage before replacements?

I just recently bought a Mini Cooper Countryman S All4 and it is my first time on run flats. I need to buy winter tires but I don't know what to use for TPMS.Is there a standard brand or type?
Friday, October 5, 2012 by Tucker

Dave, if you buy a winter wheel and tire package from us, we offer the same sensors that Mini is using when the vehicles are brand new. So they will work the same way as the stock sensors. However, if you are only buying tires, and switching out on the original wheels, there is no need to purchase any additional sensors. They are attached to the wheel opposite the valve stem. If you just change tires, the sensors will stay put. If you have any further questions, call me at 800-428-8355 extension 738. You can also reference my name if you place an order so I can watch over it for you.

Will the new snow tires and wheels I order for my 2013 550XI automatically sync the TPMS to the car? Will I have to take it to the dealer? This is the one thing holding me back. Please let me know.

The sensors don't automatically sync to the computer of the car, but there is a simple relearn procedure you can do that is detailed in your owner's manual. You won't have to go back to the dealership for sensor training. If you have any further questions, call me at 800-428-8355 extension 4738. You can also reference my name if you place an order so I can watch over it for you.

I have a 335i with 18" stock RFT tires. If I change to 20" wheels with non RFT tires what does the TPMS sensor do? Does the TPMS still work?

Thank you
Thursday, February 28, 2013 by Tucker

Yes, the TPMS sensors will still work just fine if you switch to non runflat tires. If you're doing a wheel and tire package, you'll probably want to buy new sensors at the same time. That way, we can mount and balance the wheels and tires with the sensors in. You'd just have to do a quick relearn procedure that is detailed in your owner's manual once they get there. If you have any further questions, call me at 800-428-8355 extension 4738. You can also reference my name if you place an order so I can watch over it for you.

2013 X5 came w. run flat Michelin 255/50/19. I'd like to get better puncture protection with some off road tires. I do not see any off road tires in this size. Please help.

so if i switch out the run flats for non run flats i can just pop in new tpms sensors to the new non run flat tires and i wont have any dash light or any other issues?
Wednesday, October 16, 2013 by Tucker

Unfortunately, given your vehicle and size it's not possible to go with an off-road tire with a stiffer sidewall for puncture protection. I'm sorry.
Wednesday, October 16, 2013 by Tucker

Yes, you can reuse the current sensors, or buy new ones and they will work just fine with the non runflat tires. You'll need to reset the sensors, and that can either be done with either directions in the owner's manual, or a trip to the dealership, depending on what vehicle you have.

I just placed an order for a winter wheel and tire (run-flats) package for my 2007 Mini Cooper S. I didn't see any place to add any TPMS sensors. Do they already come installed?
Tuesday, January 14, 2014 by Tucker


Do you have an order number I can look at to see what you ordered?

Can I change from run-flat to non run-flats 2 at a time? (fronts first then rears).
Monday, December 29, 2014 by Tucker


When it comes to changing out runflats, you really need to do it in a full set of 4. The construction of the two tires would be completely different, as well as the rubber compounds used, which would make the vehicle more difficult to control. Also, most installers will not install just 2 non runflat tires when there are runflat tires on the other axle.

I have a 2012 BMW X5 x35i which has R19 tires. Which are the recommended runflat and non runflat tires. I see a lot of choices at your site, so I am not sure.

I was told I couldn't just switch from run flat to regular tires on my 2012 Mini Cooper Countryman all 4. It sounds like you're saying that I could do that...
