One problem related to tire bubble has been reported for the 2011 BMW 535. The most recently reported issues are listed below.
The goodyear run flat tires on the vehicle continuously develop bubbles on the sidewall. I have had the tires replaced several times and BMW replaced because I had a tire/wheel package. Now that the tire/wheel package has expired I have been referred to goodyear regarding this matter. I do feel that this is a goodyear issue but also a BMW issue because they are installing a defected product on their vehicles. From my recent research I see there have been numerous complaints and the problem has yet to be rectified. These tires are unsafe and are a hazards. Will it take someone being killed before something is required of both BMW and goodyear to correct this problem at their expense and not the consumers????.
