Valve stem body failed during tire inflation. It is not possible to inflate tire to spec. Possible rapid air pressure loss while driving. BMW of san francisco refused to repair under existing manufactured warranty.
BMW tech looked tires over and found rear tires worn through inner edge to the point that it appears only the inner layer of rubber is holding the tire together. Full separation between the sidewall and face of the tire on both rear tires in some spots. Rear tires are dangerous and should not be used on the road or highway until replaced. The car has only 36,000 miles and the rest of the tire has tread. We feel this is well beyond normal wear and it appears that is a defect. I've attached pictures of the 2 rear tires.
Tire pressure monitor signals low air pressure every week on instrumentation. Run-flat tires lose air weekly. Tire has to be topped-up with air then tire pressure monitor test performed. Owned vehicle since February, 2016 and frequent, annoying, embarrasing tire air filling has to be done weekly.
