I had them for 14 years on my Sienna. I would avoid them on any car that you can. Very expensive and if you do end up having a flat, few places carry them to replace and they will want to replace them all. Also didn't last long. Got my first replacement based on complaints that Toyota had gotten on the longevity. I think tires were the second most expensive part of opening that van after gas.
No experience with RFT, but I would like to add most people who had bad experiences with RFT had older generations of RFT. The newer generation of RFT are much improved. The handling and ride are improved but treadwear may still be a problem, but Bridgestone has a 50-60k mile warranty on their Driveguard tires. It doesn't cost much more than their non-RFT. You can read user reviews on tirerack.com but I would just look at minivan and SUV reviews, not from people with performance cars.
Bad in snow, hard ride, no tread life, expensive to buy and replace.
Don't do it.
Agree 100%. Had two sets, including newer gen Bridgestones on my 2012 awd Sienna...absolutely horrendous. Not a single positive quality. Both sets were toast under 25k miles mostly highway and faithful rotation/balancing. Moved to standard Yokohamas and the difference is night and day. Carried and emergency kit in the car and AAA membership and luckily never needed.
I have an '05 Sienna AWD and have had no issues with the Run Flats. They have improved immensely over the years. Tread life is good and haven't had any issues with light snow. If one goes bad, you only have to replace all of them if you have an AWD vehicle. When it comes time to replace the tires on my Pachy Hybrid I will probably get those so I have some piece of mind my wife won't get stranded somewhere.
BMW forced them on everyone from 06 on and guess what all the enthusiasts hate them.
Although they have improved they suffer from.
Cost 50 percent to 100 percent more.
Have a poor ride due to stiff sidewalls.
Wear out much faster.
Are heavier than regular tires.
And are noisy when they get a little wear on them.
BMW is now offering regular tires as an option on some cars.
O and they have to be replaced if they go flat and you go any distance on them.
It seems that without a spare these would be a good idea. Anyone have experience with them?
I have them on my 2003 BMW Z4. Have had no problem with them, though they do cost more than regular tires.
Once while heading to the dealer for a free car wash, the tire pressure warning light came on. I continued on to the dealership and drove into the service department instead of the car wash line. One of the run-flats had been punctured by three screws and a two inch piece of steel had sliced into the tire. I think that would have caused a blowout on a regular tire. After that amount of damage, the tire had to be replaced.
