I have now driven my 2012 BMW 550I X drive for approximately 22,000 miles. I have been forced to replace 5 run flat tires in the past 11 months. Two Goodyear excellence rof and 3 dunlop sp sport max GT. Three tires developed bubbles on the sidewall and I cannot think of a previous impact that stood out in my mind. Two tires rapidly deflated after coming in contact with pot holes. The combination of the tight suspension along with the low profile of the run flat tires makes this combination very dangerous.

We were traveling on a highway, hit a small pothole and immediately our low tire pressure warning went off. My husband who was driving the car, pulled to safe location, got out to inspect the passenger front tire to find that the Goodyear tire had actually blown out. We had a 4 inch tear in the tire just above the rim. This is the third dunlop tire that we have had to replace with the same issues in the last three months. The first tire we had an issue with bubbled, the 2nd also bubbled but with only 100 miles on it, and then the last which actually blew out completely. We have had made numerous calls to dunlop and BMW expressing our safety concern with these tires.

After driving only a few thousand miles the tires on the car failed. The two front tires "bubbled. Within one month after, the left front failed by "blowing". in the next two months all four "new" tires failed, with the same "bubbling" issue. 4 months, 7 tires - something is very wrong with the engineering of the car as it related to the run-flat tires used by BMW creating a very dangerous riding condition. BMW service in the one service center I visited claims to change up to 15 tires per day. Multiply that by the number of service centers nationwide and you have a veritable BMW epidemic of tire failure.
