We recently had two Dunlop P 235 / 50 R 19 tires fail on our car. On 11/5/21, the front passenger-side tire tread and belt began to unravel while driving at freeway speed. This happened suddenly, with no warning lights, and we became aware of the problem when we heard a loud thumping noise from the unraveled tire striking the underside of the vehicle. We immediately exited the freeway, found a tire shop, and had the tire replaced. The following week, I inspected the other tires and found that the front drive-side tire was failing in exactly the same way. We immediately had that one replaced too. Neither tire shop that replaced the tires could identify a cause of the tire failures other than possible defects in the tires.

THIS VEHICLE CAME FROM THE MANUFACTURER WITH DUNLOP SP SPORT 01 A TIRES (225/40R18) (AUGUST 2012 PURCHASE). WITHIN NINE MONTHS (8800 MILES) TWO TIRES DEVELOPED SIDEWALL BUBBLES. AFTER CONTACTING DUNLOP, THEY REPLACED TWO TIRES ST NO CHARGE. AT THAT TIME, THE GOODYEAR/DUNLOP RETAIL STORE SLOWED ME TO PURCHASE A TIRE WARRANTY ON ALL FOUR TIRES. OVER THE PAST SIX YEARS AND 80,000 MILES, I HAVE REPLACED FOURTEEN (14) OF THESE TIRES UNDER THE WARRANTY AND HAVE HAD TO PURCHASE A WARRANTY WITH EACH REPLACEMENT TIRE. THESE TIRES ARE THE ONLY TIRES I HAVE EVER OWNED IN ALMOST 40 YRS OF DRIVING THAT HAVE DEVELOPED SIDEWALK BUBBLES. I HAVE OTHER TIRES FROM A DIFFERENT MANUFACTURER WITH THE SAME SIZE TIRE ON A DIFFERENT VEHICLE AND THEY HAVE NOT DEVELOPED ANY SIDEWALL BUBBLES. THESE TIRES ARE A SAFETY HAZARD AND SHOULD BE RECALLED AND REPLACED BY GOODYEAR/DUNLOP. THE FIRST BUBBLE WAS 6/14/13 AND THE LATEST BUBBLE WAS 9/8/18.
