I WAS DRIVING ON HWY 495 WHICH IS A CITY ROAD TOWARDS HWY 19 DRIVING APPROX 53 MPH IN CRYSTAL RIVER, FL. THE VECHILE AHEAD OF MY MINE WAS 3 CAR LENGTHS AHEAD WHEN I SAW THERE BRAKE LIGHTS ON, I APPLIED THE USUAL APPROPRIATE BRAKE PRESSURE WHICH IS NO HARDER OR SOFTER THEN ANY OTHER TIME. ONCE I SLOWED DOWN TO 40 MPH IN THE BACK PASSENGER SIDE REAR TIRE FELT LIKE IT EXPLODED AND HEARD A HUGE EXPLOSIVE TYPE SOUND AND ACTUALLY FELT THE ENTIRE BACK END OF MY SILVERADO LIFT UP AND SHIFT LEFTWARDS INTO THE OPPOSITE LANE CAUSING MY TRUCK TO ALSO GET STRUCK BY ANOTHER TRUCK CAUSING WHAT WAS A EXTREMELY WELL MAINTAINED TRUCK WITHOUT A SINGLE DING OR MECHANICAL ISSUES UNTIL THIS OCCURRED. I AM A ENGINEER AND HAVE NEVER WITNESSED A TIRE THAT LOOKED THE WAY THIS DID , BY SIMPLY DRIVING . I HAVE ALL RECORDS FOR MAINTAINCE,ROTATIONS ETC.. OVERALL I HAVE MADE MULTIPLE COMPLAINTS AND HAVE SPENT 3500 ON TIRES AND REPAIRS AND STILL THE TRUCK NEEDS 4500 MORE . I ALSO HAVE HAD TO REPLACE THE RIM THAT THE TIRE WERE ON AND THESE WERE THE RECOMMENDED TIRES FOR MY TRUCK.
