I have had 5 tire blow outs on my 2019 CLS 450 Mercedes. I purchased the car in August of 2023 and since that time I have experienced 5 tire blow outs on brand new tires within a 1-year time frame. When I got the tire blow outs all of them were while I was driving in local city traffic. This car uses run flat tires. I am having the tires replaced at Discount Tire stores in California. The tire is the following: BRI Potenza 245/35 R20 95 Y. This incident happened on several dates [XXX, XXX, XXX, XXX, XXX]. I have taken the car to the Mercedes dealership Escondido Mercedes.S.C. 552(B)(6)

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.

SIDEWALL SEPARATION (RIGHT FRONT) ON BRIDGESTONE SIZE 225/40R18 REO50A ORIGINAL EQUIPMENT RUN FLAT TIRE AT 20,000 MILES. THESE TIRES SEEM PRONE TO DELAMINATION. VERY POOR TREAD MILEAGE FOR HIGHWAY DRIVING. WORN OUT NOW. UTQG RATING SEEMS EXAGGERATED AS I'M NOT IN STOP-AND-GO DRIVING MODE. THESE TIRES ARE PRICED $70+ TO $90+ PER TIRE MORE THAN NON-RF TIRES AND B'STONE HAS A VIRTUAL MONOPOLY....BMW N.A. ONLY PERMITS REPLACEMENT OF THESE TIRES AND IT REALLY HITS THE POCKET BOOK. CONTACTED B'STONE CONSUMER RELATIONS AND MET A BRICK WALL AS THEY KNOW THEY HAVE YOU OVER A BARREL. WROTE THE PRES. OF BRIDGESTONE AND NOT EVEN THE COURTESY OF A RESPONSE.
