2001 THOR CALIFORNIA WANDERER Structurebody Problems

WHILE PULLING A 2001 28FT TOYHOUSE TRAILER IN NEVADA ON HWY 50 LATE AT NIGHT I HAD A TIRE COME APART ON ME. THE TIRE NEVER LOST AIR AND I DROVE ABOUT 10 MILES ON IT. WHEN I GOT TO WHERE I WAS GOING, I SAW THE SIDE OF MY TRAILER WAS DAMAGED. THANKFULLY NO ONE WAS HURT AND WE DID NOT CRASH. ALTHOUGH THERE WAS ALOT OF DAMAGE DONE. THEN, 3 WEEKS LATER, DRIVING ON HWY 395 IN NEVADA, THE FRONT TIRE ON THE SAME SIDE CAME APART. THIS ALSO CAUSED ALOT OF DAMAGE. NOW ONE OF THE TIRES ON THE OTHER SIDE IS CRACKING AT THE TREAD. IT TOO LOOKS LIKE IT IS COMING APART. WHEN I SENT THE TIRES TO CONTINENTAL TIRES THEY INVESTIGATED THEM AND GOT BACK TO WEEKS LATER AND SAID ONE TIRE THEY WOULD EXCEPT AS THERE FAULT AND THE OTHER WAS OVER INFLATED...
