NHTSA Complaint #10416584 — 2006 BMW 330XI

I HAVE A 2006 BMW 330XI WITH 28,000 MILES. IT CAME WITH BRIDGESTONE POTENZA RE050A RUN FLAT TIRES. I HAVE HAD 6 TIRE FAILURES, ONE OF WHICH WAS A BLOWOUT, ALL FROM THE SAME CAUSE ---SIDEWALL BUBBLES/BULGES. THERE IS CLEARLY SOMETHING WRONG WITH THESE TIRES JUDGING FROM THE NUMBER OF SIMILAR COMPLAINTS ON TIRERACK.COM. I HAVE SO LITTLE CONFIDENCE IN THESE VERY EXPENSIVE TIRES THAT I'VE PURCHASED ROAD HAZARD PROTECTION WITH THE LAST FIVE TIRES AT A COST OF $245. I'VE SPENT A TOTAL OF $1,640.27 FOR REPLACEMENT OF THESE TIRES, EVEN THOUGH THEY WERE COVERED BY THE ROAD HAZARD PROTECTION AND BRIDGESTONE AGREED TO REPLACE 2 TIRES AT HALF PRICE. THE HUGE SAFETY CONCERN OF CATASTROPHIC SIDEWALL BLOWOUT IS THE PRIMARY REASON I AM POSTING THIS. SOMETHING SHOULD BE DONE. *KB
