NHTSA Complaint #11537626 — 2022 FOREST RIVER CHEROKEE

When doing a walk around I found a very large bubble on the sidewall facing under the trailer. If it contacted the leaf springs, it was only 1" away, it would have blown. The tire is a Castle Rock ST235/80R/E. I have a TPMS system that I monitor all the time all the tires were within compliance when I found the problem, 85 psi to 90 psi. There was no damage we installed the spare and took our time heading home, less than a two-hour trip. I went to a tire shop and had all five tires replaced. While replacing the tires the mechanics found another bubble on the side wall facing inside on another tire same make and size. I had all the tires inspected by the tire road service company. The only warning I had was the visual inspection, looking under the trailer. If one of these tires exploded there could have been a major crash since they are on a Firth Wheel Toy Hauler and a possibility of someone getting severely hurt or killed. There are numerous complaints on social media. I don't understand how our government can allow this manufacturer to continue making these defective tires.
