2006 GMC Yukon Denali

ON AUGUST 31, 2010 WHILE DRIVING NORTH NEAR RED BLUFF, CALIFORNIA ON INTERSTATE 5 (I-5) AT 60 MPH WHEN WE INCURRED A CATASTROPHIC FAILURE OF THE RIGHT REAR GOODYEAR WRANGLER TIRE ON OUR GMC YUKON DENALI. THESE TIRES ARE OEM TIRES FROM GMC AND HAVE NEVER BEEN OFF THE VEHICLE FOR ANY REPAIRS ' ONLY REGULAR TIRE ROTATIONS. WE IMPACTED NO ROAD HAZARDS TO CAUSE THIS FAILURE AS WITNESSED BY THE FOLLOWING: 1.I OBSERVED NO ROAD HAZARDS PRIOR TO TIRE FAILURE. 2.GRANT - LES SCHWAB TIRE CENTER EMPLOYEE WAS RIGHT BEHIND ME AND OBSERVED NO ROAD HAZARDS. GRANT STOPPED TO ASSIST US WITH CHANGING THE TIRE. 3.THE TIRE BEAD WAS SEPARATED AND SIDEWALL SPLIT YET NO DAMAGE WAS CAUSED TO THE WHEEL RIM AS NOTED BY REDDING, CA. WINGFOOT EMPLOYEES AND GRANT AND DON - LES SCHWAB TIRE CENTER EMPLOYEES. THE LOGIC BEING THAT IF A ROAD HAZARD CAUSED FAILURE OF THE BEAD IT WOULD HAVE DAMAGED THE RIM TOO. I HAVE PICTURES ON FILE. FROM WHAT WINGFOOT AND LES SCHWAB EMPLOYEES PLUS INTERNET ARTICLES TELL ME, THE FAILURE OF THIS TIRE WAS DUE TO A DEFECT IN MANUFACTURING. WITH THIS AND THE SAFETY OF MY FAMILY IN MIND, I REPLACED ALL FOUR TIRES DESPITE STILL HAVING 50% TREAD LIFE LEFT ON THE GOODYEAR TIRES. THE DAMAGED TIRE WAS DROPPED OFF AT WINGFOOT, LLC REDDING, CALIFORNIA FOR FEDEX PICKUP TO THE GOODYEAR FACTORY FOR EXAMINATION. I HAVE RECEIVED A CLAIM DENIAL LETTER FROM GOODYEAR AFTER TIRE EXAMINATION STATING THAT OVER DEFLECTION CAUSED THE TIRE FAILURE. LOGIC DOES NOT HOLD TRUE FOR THIS DETERMINATION. IF TRAVELING ON A STRAIGHT HIGHWAY THE TIRE OVER DEFLECTION WOULD HAVE OCCURRED TO THE RIGHT FRONT TIRE DAMAGING IT AS WELL AS THE RIGHT REAR BUT ONLY THE RIGHT REAR TIRE SUFFERED A CATASTROPHIC FAILURE. *TR
