2007 Jeep Wrangler Tires Problems

PURCHASED GOODYEAR WRANGLER SR-A 255/55/17 A LITTLE OVER A YEAR AGO. ABOUT 3 MONTHS AFTER PURCHASE MY FRONT LEFT TIRES WAS FLAT AND UNREPAIRABLE. AT THAT TIME DIDN'T THINK MUCH OF IT. BUT AS TIME WENT BY I NOTICED THAT ONCE I HIT SPEEDS OF ABT 50 MPH MY FRONT END STARTED TO SHAKE SEVERELY. I ASSUMED THAT I NEEDED A FRONT END ALIGNMENT OR BALANCING. HOWEVER COMING HOME SEVERAL DAYS AGO MY FRONT AND BACK RIGHT TIRES BLEW. LUCKILY I WAS DRIVING AT A LOW RATE OF SPEED AND WAS ABLE TO CONTROL MY VEHICLE AND NO OTHER VEHICLES WERE PASSING OR BEHIND ME. IT COULD HAVE BEEN A DIFFERENT OUTCOME IF SO. I DECIDED TO DO WEB RESEARCH TO SEE IF THERE WERE ANY SIMILAR ISSUES AND HAVE FOUND MANY WITH THE SAME PROBLEM. I REALLY DO THINK GOODYEAR NEEDS TO REALLY LOOK INTO THIS. I REPLACE THE TIRES WITH ANOTHER BRAND AND NOT ONCE HAS MY FRONT END SHAKEN LIKE PREVIOUSLY. *TR

TIRE VALVE STEM FAILURES, STEM MDL TR-413, ORIGINAL FACTORY WHEELS/TIRES ON 2007 JEEP WRANGLER PURCHASED IN FEBRUARY 2007. RT FRONT TIRE WENT FLAT WHILE PARKED. NOTICED THE VALVE STEM WAS SEPARATING. CHECK OTHER TIRES AND LEFT FRONT STEM WAS ALSO SPLIT AND HISSED WHEN FLEXED. JEEP DEALERSHIP SAID IT WAS NOT COVERED UNDER WARRANTY AND SAID TO CONTACT TIRE MANUFACTURER WHEN MY SON CALLED THEM. I CALLED AND LEFT MSG FOR DEALERSHIP SERVICE MANAGER WHO NEVER RETURNED CALL. TOOK VEHICLE TO A LOCAL TIRE SHOP AND ALL FIVE STEMS REPLACED. ALL FIVE ARE MDL TR-413. VEHICLE OWNED BY MY SON. *TR
