I had a trailer tire (Powerking Towmax ST235/80r16 10PR) fail on a recent trip. The tread of the tire came completely off leaving the sidewall intact. When I removed the tire from the wheel to put on the spare the tire was still fully inflated even though I could see the steel belts. I sent the tire to the manufacture, minus the tread. The reply said that "the missing tread made it difficult to determine the operating conditions of the tire. However, there are signs of bead damage likely occurred during the mounting process. A circumferential cut on the inside of the tire along the bead toe may have been the initiating factor leading to the permeation of air into the tire carcass. This migration of air appears to have lead to the complete failure." My question is is that even possible and if so, wouldn't the tire lose its air after the tread delaminated because of permeation of air into the tire carcass. Since I am being offered $125 to replace the tire as a goodwill gesture by the tire manufacturer if I sign a release, I am suspicious.
Any insights would be appreciated.
