I noticed bulging of the spare tire cover mounted to the back of the travel trailer. When I removed the cover I saw that a chunk of the thread was missing and large gaps were in the thread next to it. It was a brand new tire that was never on the ground. The tire was inflated to the proper air pressure. The tire is a Castle Rock trailer tire size ST205/75 R14. ST 226.
