2011 Toyota Tundra Tires & Wheels Problems

THE TUNDRA IS A 2011 AND THE REAR DRIVER SIDE WHEEL HAS BEEN THE ISSUE. I WAS ON A CITY STREET ABOUT 2AM WHEN A LOUD CRASH AND THUNDERING MADE DRIVING VERY HARD. THE REAR WHEEL HAD SHEARED OFF AND WAS PASSING ME BY AS I SLOWED DOWN SPARKS FLYING LIKE THE FOURTH OF JULY!! I HAD BEEN GOING 25 MILES AN HOUR IN A RESIDENTIAL SETTING. I HAD THE TRUCK TOWED TO THE DEALER WHOM AGREED THIS WAS AN OBSCURE OCCURRENCE, TO WHICH THEY WARRANTIED AND FIXED IT. THIS OCCURRED AT 250,000 MILES SO THAT SEEMED LIKE A SATISFACTORY ENDING! HOWEVER, AT 3500 MILES LATER GOING 70MPH DOWN INTERSTATE 20 AT 4 AM A HORRENDOUS CRASH ( NOISE) AND ALMOST FLIPPING THE SAME TIRE SHEARED AGAIN PASSING ME BY!! I WAS LUCKY THAT I DIDNT FLIP! TOYOTAS EXPLANTION... THEY COULDNT/WOULDNT PROVIDE ME ONE BUT DID FIX MY PROBLEM AS THE FRICTION SANDED DOWN INTO THE ROTOR AND SHOCK ABSORBER HANGER!! NOT SURE IF OTHER FOLKS HAVE HAD THIS EXPERIENCE?? I DID ENCOUTER ANOTHER FELLOW (MY SON) WHOM HAD THE SAME EXPERIENCE AT 250,000 MILES ON THE DRIVER SIDE REAR WITH A TOYOTA TUNDRA 2012 HE OWNED. THIS IS VERY DANGEROUS AND NEEDS TO BE ADDRESSED AS TO WHAT THE ROOT CAUSE IS!! I FELT LIKE TOYOTA TOOK CARE OF ME REPAIR WISE BUT NEVER GOT A STRAIGHT ANSWER FROM THEM ON THE CAUSE!! I WOULD APPRECIATE YOUR AGENCY AND ITS RESOURCES LOOKING INTO WHAT IS CAUSING THIS DANGEROUS CONDTION

BOUGHT A CERTIFIED TOYOTA TUNDRA EQUIPPED WITH BF GOODRICH ALL TERRAIN T/A-BAJA CHAMPION TIRES--LT285/55R20-3PLY-RADIAL-HAD TO REPLACE A TIRE DUE TO A CRACK ON THE TREAD WHICH WAS CAUSING VIBRATION-UPON INSPECTION OF OTHER TIRES WE NOTICED CRACKS ON THE TIRES--VERY CONCERNED WITH OUR SAFETY-WE HAVE 1800 MILES ON THE TRUCK WHICH WE HAVE ONLY DRIVEN IT 8000 MILES SINCE WE BOUGHT IT WITH 10000 MILES WE DON'T ABUSE OUR TRUCK --WE ARE VERY CAREFUL AS WE ARE SENIOR DRIVERS- ARE WE AT RISK OF TIRE FAILURE RISKING OUR LIVES? *JB
