AFTER THE FIRESTONE PROBLEM, I NEEDED NEW TIRES ~40K. I WENT TO GOODYEAR, THEY DIDN'T HAVE AN "E" RANGE TIRE IN THIS SIZE SO THEY PUT "D" LOAD RNAGE TIRES ON. AFTER 5000 MILES, FIRST ROTATION, THERE WERE BUBBLES ON ALL FOUR TIRES. THEY REPLACED THEM UNDER WARRANTY. AT THAT TIME THEY START TO OFFER "E" SO I SWITCHED TO "E" RANGE. AFTER 5000 MILES THEY STARTED TO DEVELOP A VIBRATION, LIKE AN OUT OF BALANCE PROBLEM. I DIDN'T HAVE TIME TO TAKE THEM IN BEFORE THE NEXT ROTATION WAS DUE. THE RIGHT REAR TIRE BLEW OUT WHILE PULLING MY BOAT DOWN THE INTERSTATE IN NEW YORK. I LOST CONTROL WHEN IT GOT DOWN ON THE RIM AND THE BOAT JACKKNIFED. IT SPUN OUT OF CONTROL INTO THE MEDIAN. POLICE WERE CALLED. VEHICLE WAS DRIVEABLE. I CHANGED TIRE AND DROVE HOME. NO PUNCTURES WERE NOTED AFTER INSPECTION BY TIRE DEALER AND INSURANCE INVESTIGATOR.. SWITCHED BACK TO FIRESTONE STEELTEX. AWAITING GOODYEARS RESPONSE. OTHER PROBLEMS NOTED AS HAVING OCCURRED IMMEDIATELY PRIOR, UNKNOWN IF CAUSAL, FOR COMPLETENESS ONLY.*AK
