NHTSA Complaint #11552196 — 2021 FOREST RIVER XLR TOYHAULER

Lionshead Castlerock ST225/75R15 Tires on XLR Boost Toy Hauler Trailer. Within 5 weeks we had 3 tires fail in 2 incidents. I have already filed on the 2nd incident, but since it asks for tire location I am filing this second complaint for first incident. In the incident in which the front passenger side tire failed, we were traveling along Hwy 2 outside of Monroe Washington headed up Stevens Pass to a campground in Eastern Washington. The tire blew out traveling about 55mph on a paved highway. When it blew a large section of tread turned into a flap that damaged the underside of the trailer tearing off insulation and vapor barrier. We had to change the tire on the side of the road with traffic passing dangerously close. Since it was almost dark when we were done and we did not have a second spare in case of another incident we took it slow up pass and had to sleep in a rest are until tire shop opened. It was dangerous changing tire on the side of the busy road and nerve wrecking crossing pass without spare, however at that time (5 weeks ago) we did not bother with reporting or contacting mfg. as we thought it was a isolated incident and maybe we ran over something. When we had 2 more tires fail within such a short time leaving us stranded again with more damage we realized this is probably a defective tire situation. At this time we have reached out to the mfg of both the tire and trailer but have not heard anything back. We had this tire replaced by Les Schwab in Wenatchee WA and put it back as the spare. There was no warning before the blowout and we check pressure and visually inspect tires regularly. This was only about about 30 miles into our cross country trip.
