2012 FORD F-350 SD Tires Problems

DRIVING 70 MPH ON EXPRESSWAY WHEN TREAD COMPLETELY SEPARATED FROM BELTS ON TIRE DAMAGING THE RIGHT REAR WHEEL WELL, BODY, TRIM AND BUMPER. TIRE WAS A FACTORY INSTALLED (BOUGHT THE 2012 F350 NEW) GENERAL GRABBER HTS SIZE 245/75 R 17 WITH 54,000 MILES ON THEM. DOT # IS A343 47DB

WHILE DRIVING ON THE HIGHWAY MY TRUCK BEGAN TO VIBRATE. I STOPPED AND CHECKED THE TIRES CONDITION, AIR PRESSURE AND LUG NUTS. ALL SEEMED TO BE FINE. I CONTINUED DRIVING AND EXPERIENCED A VIOLENT BLOWOUT FROM THE RIGHT FRONT TIRE CAUSING EXTENSIVE DAMAGE TO THE RIGHT FRONT OF THE TRUCK. I WAS TOLD BY THE TIRE STORE THAT MODEL TIRE WAS DEFECTIVE AND THEY HAD SEEN A NUMBER OF FAILURES. A CLAIM WAS FILED WITH TIRE MANUFACTURER AND DENIED. I WAS TOLD THE NEWEST MODEL OF THAT TIRE HAD BEEN IMPROVED SO THE TIRES WERE REPLACED THE TRUCK WAS SENT TO THE DEALER FOR REPAIRS.

I NOW HAVE A THIRD TIRE WITH TREAD SEPARATION. THE TIRE IS A BF GOODRICH ALL-TERRAIN T/A KO, LT285/65R20 127/124S, DOT (BE3F UH11 1313). THIS TIME THE TIRE WAS LOCATED ON THE FRONT DRIVER SIDE AND CAUSED A DEATH SHIMMY. THE TIRE STILL HAS THE TREAD ON AND CAN STILL BE INFLATED. IT WAS REMOVED FROM THE RIM FOR INSPECTION AND REPLACEMENT. NO INTERNAL DAMAGE OR CRACKS WAS FOUND INSIDE, BUT THERE ARE CRACKS IN THE TREAD THAT INDICATES THAT THE TREAD WILL SEPARATE FROM THE TIRE. ARE THEY TRYING TO HURT OR KILL ME AND MY PASSENGERS? WHAT CAN I EXPECT NHTSA AND BF GOODRICH (MICHELIN) TO DO IN RESOLVING THIS ISSUE WITH THEIR TIRES?
