1. New 2012 BMW 550xi m sport package w/approx. 6,700 miles on four oem goodyear eagle ls2 rof 245/40r19 98v (dot ne66 jp1r 3411) tires. No recollection of hitting any potholes, speedbumps, curbs, etc. 2. Noticed approx. 2. 5" x 1" bubble on front driver side tire sidewall after parking at workplace. No crashes or injuries. 3. Vehicle driven directly to BMW dealer at low speed. Service rep said tire must be replaced due to safety concerns and that he had seen several similar incidents. Dealer installed new goodyear tire (dot ne66 jp1r 0412).

The contact owns a 2012 BMW 550xi. The vehicle was equipped with goodyear tires, size 245/40/r19. The contact stated that the vehicle would vibrate when driving carious speeds. In addition, there were several bubbles on all four tires. The failure was recurring. The vehicle was taken to the dealer where the technician stated all four tires would need replacing. The tires were replaced. The manufacturer was made aware of the failure. The VIN and dot number was not available. The approximate failure mileage of both the tire and the vehicle was 39,000.

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.
