2013 KEYSTONE ALPINE Wheels Problems

THIS IS THE SECOND BLOW OUT, THE LAST TWO TIMES OUT WITHIN A MONTH. THE TIRES FAILED ON OPPOSITE SIDES OF THE RV, TIRE PRESSURES WERE CHECKED AND TOP OFF AFTER WINTER STORAGE (INDOORS). BOTH TRIPS THE OUTDOOR TEMPERATURE WAS APPROXIMATELY 90 DEGREES. BOTH SIDES OF THE RV WERE DAMAGED AFTER THE BLOW OUTS, METAL SIDING AND FENDER WELL PARTS WERE DESTROYED.

I AM A RETIRED AIRFORCE AIRCRAFT TECHNICAN.I HAVE A CDL. THEREFORE,I KNOW THE IMPORTANCE OF PROPER VEHICLE MAINTENANCE. THERE HAS ONLY BEEN 2 TRIPS(PGH.PA. & DALLAS,TEX.)ON THIS RV SINCE PURCHASED.ON THE DAY IN QUESTION,I CHECKED AIR PRESSURE OF ALL TIRES(TOW VEHICLE & RV).I WAS ON I-20 EASTBOUND ABOUT 65 MI. FROM DALLAS,TEXAS WHEN,I HEARD A LOUD BANG.THE RVPASSENGER SIDE FRONT TIRE BLEW OUT.IN ADDITION TO THE BLOWN TIRE,DAMAGE WAS DONE TO SLIDE OUT.I HAD NO PRIOR INDICATION THAT ANYTHING WAS WRONG WITH THE 5TH WHEEL I WAS TOWING.I HAD NOT RUN OVER ANYTHING THAT WOULD HAVE CAUSED DAMAGE TO THE TIRE.I DID NOT EXCEED THE MAXIMUM SPEED OF 65MPH RECOMMENDED BY TIRE MANUFACTURER(POWER KING TOWMAX STR 235/80R16E).I HAVE BEEN TOWING RV'S FOR OVER 7 YRS. I HAVE NEVER HAD A TIRE ISSUE UNTIL NOW. I ACQUIRED THE KEYSTONE ALPINE 3600RS ON 4/28/2013 AND HAVE HAD PROBLEMS WITH IT FROM DAY...
