This is partially my fault. I felt a vibration the day prior and wanted to ride in the trailer briefly to see. Yes I know not a good idea in a folded up hardside.
It blew in the dark next morning before I had that chance. A TPMS would not have helped as it went from 60 to 0 instantly.
I have since done a lot of research. ALL of the ST tires are prone to this. Anyone with tires large enough to have a LT tire should go that route. There are no LT tires in 13".
Now running Goodyears but they have reports of tread separation as well.
For now I will change them every season. A lot cheaper than the $3800 repair.
The only good that came out of it was the shop refused to recreate the silly propane hose in the hatch and made a nice external quick release aft of the wheel well.
The propane hose was eaten by the belts and venting into the area which had 12 v wires sparking
