2006 Forest River Travel Trailer

WHILE TRAVELING SOUTHBOUND, JUST CROSSED MASON-DIXON LINE ON THE INTERSTATE, HAD A BLOWOUT ON THE LEFT FRONT OF MY 5TH WHEEL CAMPER. THE BLOWOUT CAUSED DAMAGE TO THE WIRING GOING TO THE SLIDEOUT AND PART OF THE STRUCTURE. THE TIRE APPEARED TO SEPARATE AT THE TREAD AREA WHICH SHOWED ALSO TO APPEAR TO NOT BE SEALED TO THE CARCASS AND WAS NOT CLEAN BETWEEN TREAD AND CARCASS. THIS HAPPENED AGAIN ON 06 JULY 2014 ON MY RIGHT REAR. ACCORDING TO THE MECHANIC THAT PROVIDED ROADSIDE ASSISTANCE INDICATED THAT IT APPEARED THAT THE TREAD SEPARATED AT CARCASS AREA AND APPEARED TO NOT BE PROPERLY SEALED. THE TIRES ARE CARLISLE RADIAL TRAIL ULTRA CRT ST205X75X15 *JS

MY 10,000LB 5TH WHEEL CAME EQUIPPED FROM THE FACTORY WITH DURA KING LT236/85R16 TIRES. THE LOAD RANGE IS RATED AS E 3,042LBS SINGLE AXLE AND 2,778 DUAL. MY 5TH WHEEL HAS TWO AXLES WITH TWO TIRES PER AXLE. WITHIN THE LAST MONTH ALL FOUR TIRES HAVE BLOWN OUT. THREE WITHIN THE LAST WEEK AND TWO IN A SINGLE DAY. I WOULD ESTIMATE THAT THE LAST THREE TIRES BLEW OUT WITHIN 300 MILES OF EACH OTHER. EACH OF THE LAST THREE TIMES I HAD A PROFESSIONAL REPLACE THE TIRES AND CHECK THE AIR PRESSURE IN EACH TIRE TO BE SURE IT MET THE STANDARDS. I ALSO CHECKED THE TIRES TO INSURE THEY HELD THE CORRECT PRESSURE. EACH TIRE REPAIRMAN INDICATED CONCERN THAT THE TIRES WERE FOR LIGHT TRUCKS AND NOT TRAILER TIRES. TWO OF THE FOUR BLOWOUTS CAUSED SIGNIFICANT DAMAGE TO MY VEHICLE. UPON REPORTING THE PROBLEMS TO FOREST RIVER THERE WAS LITTLE CONCERN. THE 5TH WHEEL IS A 2006 MODEL AND THE TIRE REPAIRMEN INDICATED THE TIRES WERE MADE IN 2004. SHOULD MY FIFTH WHEEL BE EQUIPPED WITH LIGHT TRUCK TIRES INSTEAD OF TRAILER TIRES? WHY ARE THERE 2004 MODEL TIRES ON MY 2006 TRAILER? SHOULD THERE BE 2004 TIRES ON A 2006 TRAILER THAT WAS SOLD AS NEW? *TR
