2004 KEYSTONE MONTANA Complaints

I WAS PULLING A 2004 TRAVEL TRAILER THAT HAS ABOUT 3000 MILES ON IT. TWO TIRES FAILED/SEPARATED AND BLEW OUT. WHEN THE FIRST BLOW-OUT HAPPENED THE TRUCK I WAS PULLING THE TRAILER WITH BEGAN TO VIBRATE AND THEN WITHIN 2 SECONDS, BEFORE I COULD SLOW DOWN, A LOUD POP CAME FROM THE TRAILER AND BY THE TIME I STOPPED THE TIRE WAS SHREDDED. I CHANGED THAT TIRE WITH THE SPARE. 30 MILES LATER ANOTHER TIRE BLEW. THIS TIRE WAS LOCATED ON THE OPPOSITE SIDE OF THE TRAILER ON A DIFFERENT AXLE. IT BLEW OUT WITH THE SAME TRUCK VIBRATION AND POP AS THE OTHER ONE. THEN I LOOKED AT THE OTHER TIRES AND FOUND A THIRD TIRE WAS SEPARATING, THE TREAD WAS LIFTING AND WIRE CORDS WERE COMING OUT. ALL 5 TIRES, INCLUDING THE SPARE WERE REPLACED. THE TRAILER HAS BEEN DAMAGED BUT I HAVEN'T BEEN TO A RV DEALER FOR ESTIMATES AT THIS TIME. I SEARCHED FOR COMPLAINTS BUT THIS TIRE BRAND ISN'T LISTED. I KEPT THE OLD TIRES BECAUSE I FIGURED THE DEALER WOULD WANT TO SEE THE ORIGINAL TIRES AND DOT'S BEFORE THEY COULD BE WARRANTED IF A WARRANTY IS VALID. THESE TIRES ARE MISSION BRAND TIRES - SIZES ST225/75R15. THE DOT #'S ARE 1- WEHH 2735103 2510, 1- WEHH 2735103 2610, 1- WEHH 2735103 2504, AND 2- WEHH 2730504 03 THIS INCIDENT HAPPENED JULY 31ST WHEN WE WERE TRAVELING TO GRAND JUNCTION, CO. THE WEATHER WAS HOT (100'F), AND SUNNY. I HAVE READ NUMEROUS COMPLAINTS FROM OTHER PEOPLE ON THE RV.NET FORUM. THEY ARE HAVING BLOW-OUTS AND TIRE SEPARATIONS THE SAME AS I HAVE. *NM
