TIRE - TREAD SEPARATION VEHICLE - FORD EXPLORER (1998) TIRES - FIRESTONE (PURCHASED SOMEWHERE IN THE 2003-2005 TIMEFRAME). THESE TIRES WERE SNOW TIRES AND ARE USED ONLY A FEW MONTHS OUT OF EACH YEAR, SO THERE IS LOW MILEAGE ON THEM. AT APPROXIMATELY 1 PM, MY DAUGHTER LEFT A SCHOOL FUNCTION IN BURBANK, WA, AND TURNED ONTO HIGHWAY 12. SHE ACCELERATED; ABOUT 100 YARDS LATER, JUST AS SHE REACHED THE SNAKE RIVER BRIDGE, THE LEFT REAR TIRE LOST ITS TREAD. SHE WAS GOING LESS THAN 50 MPH. THE CAR WAS UNCONTROLLABLE, SPUN AROUND, AND SMASHED INTO THE CONCRETE BARRIER OF THE BRIDGE. THE CAR WAS SEVERELY DAMAGED (TOTALED). NO OTHER CARS WERE INVOLVED. *TR
