“ALL FOUR TIRES DEFECTIVE AND DANGEROUS 1.On February 10, 2020 we purchased four Goodyear Assurance Weatherready tires from Riverside Garage (19 East Ave., Riverside, 60546 708-447-7221 (see attached receipt) 2.On August 5, 2022 the rear/driver’s side tire went flat in Springfield, Illinois during a family visit. We were unable to reinflate the tire. Discount Tire inspected it and found a 12 inch or greater slit and a 1-1/2 inch slit on the inside wall of the tire (see attached photos). The slits revealed white mesh inner membrane. It was unsafe to use, so Discount Tire replaced it. 3.On August 7, 2022, while on route back to Riverside, Illinois from Springfield, Illinois on Interstate 55 we observed a “low tire” light another Assurance tires at rear/passenger side tire. 4.On August 8, 2022 Riverside Garage inspected the rear/passenger tire to find a 1-1/2 inch slit on the inside wall of the tire, which was similarly situated as the other tire. It also revealed an interior mesh membrane similar to the other flat tire. Further inspection of the remaining two tires showed faint “lines” similarly positioned across the inside walls of the remaining front two tires.…”

5 reports5 crashes
“AT APPROXIMATELY 2:00 PM ON JAN. 5, 2020, I WAS DRIVING MY 2006 LEXUS LS 430 IN A RESIDENTIAL AREA IN BETHESDA, MD. I DECIDED TO TURN AROUND. I TURNED RIGHT INTO A DRIVEWAY (AT A LOW SPEED) WITH THE BRAKE PEDAL APPLIED. SUDDENLY, AND WITHOUT WARNING, THE CAR ACCELERATED WILDLY, MAKING A GREAT DEAL OF ENGINE NOISE, AS THE THROTTLE APPEARED TO BE WIDE OPEN. THANKFULLY I HIT A NEAR-BY TREE AND TWO FRONT AIR BAGS DEPLOYED. A HOMEOWNER CALLED THE POLICE, AND AN AMBULANCE TOOK ME TO THE EMERGENCY ROOM AT A NEARBY HOSPITAL. IF THIS SUDDEN ACCELERATION HAD OCCURRED ON A HIGHWAY, I AM CERTAIN THAT LIVES WOULD HAVE BEEN LOST.”
