ON JULY 28, AT APPROX 4PM EST WE EXPERIENCED TREAD SEPARATION FROM THE FRONT PASSENGER TIRE THAT CAUSED OUR FORD EXPLORER TO TEMPORARILY LOSS CONTROL. THE TIRE WAS A FIRESTONE WILDERNESS TIRE THAT WAS PROVIDED BY FORD FOR A RECALL REPLACEMENT ABOUT 8 OR 9 YEARS AGO. THE RIGHT PASSENGER FRONT TIRE SEPARATED ON RT I95 NEAR THE SHARON, MA EXIT. LOUD SOUNDS CAME FROM ENGINE AREA OF CAR AND TREAD HIT SIDE OF CAR AND FP WINDOW. CAR BEGAN TO LOSS CONTROL, BUT THE DRIVER WAS ABLE TO STABILIZE AND PULL OFF OF THE HIGHWAY. WE WERE TRAVELING FROM PA TO MA (WE LEFT CONSHOHCKEN, PA AT 9:45 AM) AND I WAS AVERAGING 65 TO 70 MILES PER HOUR, BUT WAS SLOWING DOWN WHEN TREAD SEPARATED. I WAS MOVING FROM THE RIGHT TO THE LEFT LANE, EXIT WAS ABOUT 1 TO 2 MILES AHEAD OF US. THE RIGHT FRONT WHEEL WELL PLASTIC COVERING, SOME AIR CONDITIONING EQUIPMENT, AND THE RADIO ANTENNA ALL HAVE BEEN DAMAGED. THERE IS SOME PAINT DAMAGE ON RIGHT SIDE OF CAR AND THE AND RUNNING BOARD SEEMS TO HAVE SOME DAMAGE AS WELL. A ROADSIDE ASSISTANCE PERSON CAME TO HELP US REMOVE THE TIRE AND REPLACE IT WITH A SPARE. WE BROUGHT THE CAR BACK TO A FIRESTONE DEALER IN BROCKTEN, MA AND WAS TOLD THAT FIRESTORE WOULD LIKELY FIX THE DAMAGE TO THE CAR. THERE WERE FOUR OF US IN THE CAR, WE WERE ALL SHAKEN UP, AND BUMPED AROUND, NO ONE WAS CUT. A REPORT WAS FILED WITH THE ROADSIDE ASSISTANCE PERSON, BUT NO POLICE REPORT WAS FILED. *TR
