NHTSA Complaint #11476853 — 2021 GRAND DESIGN IMAGINE

On 6/17/2022 the cold pressures were set correctly for the 2021 Grand Design 2800BH travel trailer as they had been for a dozen or more prior trips. A TPMS was being used during travel to monitor pressures and temperatures. All 4 of the Westlake brand ST 225 / 75 R 15 tires with manufacturing date "3320" were inspected for bubbles, cuts, punctures, etc... prior to departure and no anomalies were observed. With absolutely NO WARNING the right rear wheel experienced a complete tread separation. The tire's entire tread was thrown from the tire in one piece, after making contact with the vehicle, while traveling at 68mph on the FL turnpike southbound. The remainder of the tire remained inflated however the steel belt was now in contact with the highway. The debris caused a multicar accident and delays on the highway according to the Road Ranger who assisted with installation of the spare. The camper itself has consequential damage in excess of $6000 that neither the tire warranty nor travel trailer warranty will cover for this manufacturing defect. The safety of myself, my family riding along, and those around me while traveling on the highway was put in severe risk of injury or death. The defective tire that was removed from the wheel has been retained.
