NHTSA Complaint #10199620 — 1990 TOYOTA PICKUP

I HAVE A 1990 TOYOTA PICKUP WITH A SET OF FIRESTONE AFFINITY TIRES IN SIZE 205/70R14. YESTERDAY WHILE ON THE WAY TO WORK ON I85 THE FRONT OF THE TRUCK BEGAN VIBRATING HORRIBLY AS IF IT HAD A FLAT TIRE. I PULLED OVER AND INSPECTED THE TIRES AND THEY ALL STILL HAD AIR IN THEM. I CONTINUED ON MY WAY BUT THE VIBRATION CONTINUED. AT THIS POINT I THOUGHT I HAD THROWN A WHEEL WEIGHT AND THE TIRE WAS OUT OF BALANCE. ABOUT 1 MILE DOWN THE ROAD THERE WAS A LARGE POPPING NOISE FROM THE LEFT FRONT TIRE. LUCKILY, I WAS ABLE TO PULL OVER INTO A GAS STATION AND WHEN I DID I FOUND THAT THE TIRE HAD A HUGE SECTION OF TREAD THAT HAD SEPARATED FROM THE TIRE CARCAS, PROBABLY 25% AROUND THE TIRE. THIS IS NOT SOMETHING I HAVE EVER HAD HAPPEN WITH ANOTHER TIRE IN 25 YEARS OF DRIVING. THIS IS AN EXTREME SAFETY HAZARD AND I FEEL LUCKY THAT I DIDN'T END UP HAVING AN ACCIDENT DUE TO THIS. THESE TIRES STILL HAVE CONSIDERABLE TREAD LIFE IN THEM AND HAVE BEEN ROTATED EVERY 5,000 MILES AND I RUN 32 PSI IN THEM. THE TRUCK IS RARELY USED FOR HAULING ANYTHING. I WOULD LIKE TO KNOW WHAT CAN BE DONE ABOUT THIS SITUATION.
