1972 CHEVROLET PICKUP Tires Problems

WHILE TRAVELING TO CALIFORNIA ON HWY95, AT APPROX. 60MPH, HEARD A NOISE, LIKE A BLOW OUT. VEHICLE WENT OUT OF CONTROL, FLIPPING OUR TRUCK AT LEAST FOUR TIMES. VEHICLE CAME TO A REST UPSIDE DOWN, PASSENGER DOOR STUCK SHUT, DRIVERS SIDE DOOR OPEN. MY HUSBAND WAS DRIVING, HE WAS NOW OUTSIDE OF THE VEHICLE, HANGING UPSIDE DOWN, WITH THE SEATBELT WRAPPED AROUND HIS NECK, AND CHOKING. I CUT HIM FREE, AND DRUG HIM AWAY FROM THE TRUCK. AFTER 30, EMT'S ARRIVED, THEY FLEW HIM BY FLIGHT FOR LIFE TO THE TRAUMA CENTER. LUCKILY, HE HAD NO SERIOUS INJURIES. IT WASN'T UNTIL AFTERWARDS, I SAW THAT THE TIRE HAD SEPERATED. PIRELLI HAS DENIED ANY RECALLS, AND WILL NOT RETURN ANY CALLS. SOMETHING HAS GOT TO BE DONE.*AK
