2009 KEYSTONE CHALLENGER Tires Problems

I HAVE A 2009 KEYSTONE CHALLENGER 5TH WHEEL THAT CAME WITH GOODYEAR MARATHON ST235/80/16 TIRES. TRAVELING ALONG THE OKLAHOMA TURNPIKE THE RIGHT FRONT TIRES EXPLODED WITHOUT WARNING. THE TIRE PRESSURE HAD BEEN CHECKED THAT MORNING AND THE TIRES HAD BEEN VISUALLY INSPECTED WITHIN 30 MINUTES OF THE FAILURE. GOODYEAR STATES THERE IS NO PROBLEM WITH THEIR TIRES AND REFUSED REPLACEMENT. HOWEVER, YOU HAVE 79 SIMILAR COMPLAINTS ON THESE TIRES LISTED ON YOUR WEBPAGE. THIS CAUSED SIGNIFICANT DAMAGE TO THE FIFTH WHEEL AND CAUSED ME TO SWERVE INTO THE OTHER LANE, LUCKILY THE VEHICLE NEXT TO ME WAS ABLE TO MOVE OVER AND AVOID ME. THIS WAS A VERY CLOSE CALL. WHILE CHANGING TIRE ON SIDE OF ROAD WE WERE NEARLY STRUCK BY A SEMI-TRUCK. *TR
