RunOnFlat. Stay Away.
 It's a first and a last time I own the car (535xi 2011)with RFT tires.I changed 4 tires already and 2 more on a way. Each one is $500.00. The problem is always same: the buble on a side of the tire. Beside the danger to drive it (to yourself and others on a road), car will not pass the inspection. There is no spare tire. If the tire goes bad at night or on Sunday, that it.If you live in an area with roads with a lot of potholes (NY) , forget about this car. States should regulate sale of cars with RFT tires. Every car has problems, but this is ripoff
