THIS COMPLIANT IS FOR A TANDEM AXLE TRAILER TIRE FAILURE USED ON TRAVEL TRAILER CAMPER. THERE ARE 3 TIRES FAILURES WITH THE SET OF 4 ON MY TRAVEL TRAILER. THIS REPORT IS FOR THE THIRD TIRE. THE TIRE IN QUESTION IS A DENMAN ST225/75R15 LOAD RANGE D. TYPE: ST EXPRESS RADIAL DOT CODE: 4FEH M5M 2908 TIRE INSTALLED: 4-5-2009 THIRD TIRE FAILURE OBSERVED ON 7-14-2012 MILES USED UNTIL FAILURE NOTICED, 11,770 MILES. THIS FAILURE IS 1,607 MILES AFTER THE FIRST TIRE FAILURE LOGGED IN NHTSA REPORT 10471651 TOWING SPEED: 55 TO MAX OF 60 MPH AS STANDARD TOWING SPEED ON HIGHWAY. AIR PRESSURE OF 65 PSI CHECKED AT THE START OF EACH CAMPING TRIP. TIRE FAILURE OCCURRED WHEN THE TIRE WAS MOUNTED IN THE FRONT RIGHT POSITION. I HAVE CERTIFIED SCALED WEIGHT SLIP THAT CAN BE PROVIDED OF THE CAMPER AFTER THE FAILURE OF THE FIRST TIRE. THE FRONT AXLE LOAD IS 4,340# ON BOTH FRONT TIRES. THE TOTAL RATED CAPACITY OF THE REAR TIRES ARE: 2,540 X 2 = 5,080# AT 65 PSI COLD PRESSURE. CAMPER VIN [XXX] CAMPER MANUFACTURE: SUNLINE COACH COMPANY, DENVER, PA MODEL TRAVEL TRAILER: SOLARIS SR, T310SR, GVWR: 10,000# GAWR: 10,000# I AM THE ORIGINAL PURCHASER OF THESE TIRES WHICH REPLACED THE ORIGINAL TIRES ON THIS CAMPER. THE SIZE, LOAD RANGE AND INFLATION PRESSURE MATCH THE OEM TIRE PLACARD. I HAVE PICTURES AND CAN SEND OF THE VIN PLATE IF NEEDED. THE TIRE HAD A TREAD BULGE INCREASING THE OD OF THE TIRE AND FOUND WHEN REMOVING THIS TIRES FROM SERVICE. SINCE TWO TIRES HAD PRIOR FAILED, I WAS REPLACING ALL 4 AND FOUND THIS FAILURE AS I WAS CHANGING THEM. THE BULGE IN THE TREAD SECTION LOOKS TO BE THE SAME FAILURE AS THE TIRE REPORT NHTSA REPORT 10471651 THE TIRE WAS REMOVED FROM SERVICE UPON FINDING THE BULGE ON 7-14-2012 BEFORE TOTAL FAILURE OCCURRED DURING TRAVEL AND TO PREVENT CAMPER DAMAGE. THE FAILED TIRE WAS REPLACED WITH A NEW TIRE OF THE SAME SIZE AND LOAD RANGE, HOWEVER A DIFFERENT BRAND. I HAVE PICTURES OF THE FAILURE AND THE COMPLETE TIRE IF NEEDED. INFORMATION REDACTED PURSUANT
