1986 FORD F250 Tires Problems

I WAS DRIVING AT 55-60 MPH ON TWO LANE HIGHWAY (NO SHOULDER) WHEN BELT AND TREAD OF RIGHT REAR TIRE PEELED OFF SUDDENLY WITHOUT WARNING. TIRE DID NOT LOSE PRESSURE IMMEDIATELY SO I WAS ABLE TO DRIVE APPROXIMATELY 50 YARDS TO NEAREST TURN OFF, PULL OFF ROADWAY, AND PUT MY SPARE ON. ON COMING AND FOLLOWING TRAFFIC HAD TO SWERVE (SOME OFF OF ROAD) TO AVOID PIECES OF DISINTEGRATING TIRE. *TR

BELT OF TIRE IS SEPARATING (TIRE FEELS OUT OF BALANCE, BULGE IS NOW EVIDENT IN TREAD, 8/32'S OF ORIGINAL 15/32'S OF TREAD REMAIN). THIS IS SECOND TIRE IN SET OF FOUR TO SEPARATE (SEE ODI REPORT # 10345185 FOR FIRST). *TR

BELT OF TIRE IS SEPARATING (TIRE FEELS OUT OF BALANCE, BULGE IS NOW EVIDENT IN TREAD, 7/32'S OF ORIGINAL 15/32'S OF TREAD REMAIN). THIS IS THIRD TIRE IN SET OF FOUR TO SEPARATE (SEE ODI REPORTS #10345185 & #10345187 FOR FIRST & SECOND). *TR

THE TIRE STARTED TO COME APART WHILE DRIVING THE OHIO TURNPIKE, SOUNDED LIKE RUMBLE STRIPS PRIOR TO CATASTROPHIC FAILURE. *AK (TIRESIZE: 265 /16)

THIS IS THE SECOND TIME I HAVE HAD A BLOWOUT WITH THESE TIRES. FORTUNATELY THERE HAVE BEEN NO INJURIES, ONLY DAMAGE TO MY VEHICLE. IF I WAS ON A MOUNTAIN ROAD, OR DRIVING ALONT THE COAST THIS COULD HAVE BEEN MUCH MORE SERIOUS. BOTH TIMES VEHICLES HAD TO SWERVE INTO ADJACENT LANES TO AVOID TIRE DEBRIS (AND ME). I HAVE REPLACED ALL FIRESTONE TIRES AT MY EXPENSE. THESE TIRES ARE NOT SAFE. I HAVE A FULL SIZE CAMPER ON THIS TRUCK, AND WHEN A TIRE BLOWS DIRECTIONAL CONTROL IS QUITE DIFFICULT TO MAINTAIN. IN OVER 400,000 MILES OF DRIVING I'VE HAD 2 BLOWOUTS. BOTH FIRESTONE STEELTEX AT. *AK (DOT NUMBER: VDOR1WW485 TIRESIZE: 23585R16)
