NHTSA Complaint #10985777 — 2015 JAYCO FIFTH WHEEL EAGLE PREMIER

LAST SUMMER THREE OF FOUR POWER KING TOWMAX STR'S ST235/80R16 TIRES THAT CAME WITH MY NEW 2015 JAYCO EAGLE 375BHFS EXPLODED. AT THE TIME OF THE FAILURE THE TIRES HAD ONE SEASON OF USE, ABOUT 6000 MILES. ABOUT FOUR HOURS INTO OUR FIRST TRIP THE RIGHT REAR TIRE EXPLODED. AN HOUR LATER, THE RIGHT FRONT TIRE EXPLODED. IN ORDER TO COMPLETE OUR JOURNEY I HAD TO REPLACE BOTH TIRES WITH THE SAME TOWMAX TIRES. SEVEN WEEKS LATER, THE LEFT FRONT TIRE EXPLODED. ON DECEMBER 23, 2016 THE TIRE MANUFACTURE, DYNAMIC TIRE CORPORATION, WAS PROVIDED NOTICE OF THE POTENTIAL HAZARDS I OBSERVED AS A LICENSE PROFESSIONAL ENGINEER: THE ISSUE, HOWEVER, THAT IS PARAMOUNT WITH THE FAILURE OF THESE TIRES, IS THE EVIDENCE OF EXCESSIVE HEAT BUILDUP AS YOU STATED IN YOUR REPORT IS INDICATED BY THE BLUE DISCOLORATION. THIS IS EVIDENT NOT ONLY IN THE REMAINING TWO ORIGINAL TIRES BUT IS ALSO PRESENT IN THE TWO REPLACEMENT TIRES CONTRARY TO YOUR REPORT, THE ORIGINAL TIRES AND THE REPLACEMENT TIRES WERE NEVER OPERATED IN AN UNDERINFLATED CONDITION OR EXPOSED TO LOADS GREATER THAN INDICATED ON THE SIDEWALL OF THE TIRES. ALL TIRES WERE CLOSELY MONITORED BY MYSELF AND IT IS MY PROFESSIONAL OPINION THAT THESE TIRES GENERATED EXCESSIVE HEAT DURING THEIR OPERATION WITHIN THE MANUFACTURES OPERATIONAL REQUIREMENTS FOR PRESSURE AND LOAD. WITH THE FAILURE OF THE THIRD TIRE IT BECAME APPARENT TO ME THAT THE MATERIALS AND CONSTRUCTION OF THE TIRE ARE NOT ABLE TO OPERATE AT THE MANUFACTURES RATED CAPACITY. SINCE THERE EXISTED A REAL PROBABILITY THAT THESE REPLACEMENT TIRES WILL ALSO EVENTUALLY FAIL BOTH REPLACEMENT TIRES WERE ALSO REMOVED FROM SERVICE AT THAT TIME. IT IS MY PROFESSIONAL OPINION THAT DTC NEEDS TO GIVE SERIOUS CONSIDERATION TO EXAMINING THE CAUSE FOR THE EXCESSIVE HEAT BUILDUP IN THEIR TIRES AND THE RESULTING DEGRADATION OF MATERIAL STRENGTH THAT OCCURS OVER TIME AND REEVALUATE THE RATINGS INDICATED BY DTC ON THE SIDEWALL.
