Driving 30 mph tpms light came on indicating front driver tire low, got home and took tried to inflate tire, with no luck. Took tire off and the inside tire wall had blown out. 1 month later the same blow out occurred on passenger rear tire. There was good tread on both tires. Don't know if it matters, but both tires where run flat. I have contacted bridgestone, but no response. I'm attaching pictures.
The wheels/rims on my BMW are contributing to my tires faults. The bridgestone potenza rts tires are constantly having bubbles form on the tires with normal driving. I have replaced several tires as a result. They tell me it is road hazard. If that was the case I would have replaced tires on my other cars that I drive much more frequently. Last week another blowout on interstate 395 in va. $500 for a new tire and then they find another tire with a bubble. BMW is at fault as well.
Rear alloy wheel is cracked resulting in loss of pressure. No impact occurred to cause this crack.
I just discovered that the left rear rim on my 2007 BMW 328 convertible is cracked. My car has less than 38k miles on it. The tires are 225/45 17� run-flats. I had four new tires put on about 6 months ago. I got the ¿low tire pressure� warning light about a week ago when I started the car. I checked, didn¿t notice anything, and reset the tpm successfully. Since it was a cold morning, I figured the sensor was just reacting to pressure change due to the temperature change. A few days later, it came again. I decided to check, and found the pressure was down to about 25 psi. I filled the tire to recommended psi. I drove about 260 miles on Sunday, mostly freeway speeds. When I was about 30 miles from home, the warning light came on again. At that time I was on a freeway, going about 70 mph. Once I got to home, I filled the tire (again it was about 25 psi), and the warning stopped. Yesterday the light came on, and I took it to my local tire shop. They didn¿t find a puncture; but remounted it and filled it. I drove home, and a few hours later, the warning came on again. This morning, I took it back to the shop, and they again removed the tire. This time they did a very close inspection and found the crack in the rim. They are ordering me a replacement rim. From what I have seen on the internet, there seems to be a problem with the BMW rims and run-flat tires. This is definitely a safety issue, if the rim would have a catastrophic failure while the car was traveling at highway speeds this could be deadly.
I just purchased a 2007 used BMW 328xi with ~45k miles. One week to the date of purchase, the tire pressure warning light came on in the car. I took it to the dealership (still under warranty for 5k more miles) and they told me I had a cracked rim, "likely due to impact. " I have driven it only on roads under normal conditions, hitting no significant potholes or other road obstructions. The rim is not covered under warranty and will cost ~$500 to replace. I checked this out incident reports online and it seems that many people have complained about the rims/run-flat tires being defective under normal driving conditions.
Runflat tires on BMW 328xi are not suited to american roads. Hit a pothole on the highway with the runflat tires. Wheel was damaged and tire was damaged as well. Runflat tires seem less resilient than standard tires, and result in greater likelihood of wheel damage. Tire did not go flat, but wheel and tire need replacement.
