We had a tire blow on us last summer; the tires in question were probably about 2 years old, but had seen heavy use. Fortunately no other damage to the trailer, and we were lucky to have an entire lane to wait in for help - that area was under construction, with the left lane blocked off for many miles. I think that tire had been one that had shown signs of unusual wear, and was most likely related to prior problems with the wheel hubs on that same camper. Glad you came out ok; hope the Cardinal did the same.
