Carlisle ST tire failure, or puncture damage? UPDATE

Sounds like some are trying awful hard to blame the OP for this.

A TPMS will do nothing for you if the tire just suddenly fails mechanically and bursts.

I see no abrasion to the side walls at all so it's unlikely OM hit a curb or water ever.
In the third pic I do see a raised area perpendicular to the wheel that would suggest internal seperation.

Glad you didn't have any trailer damage. I've had it go both ways - sometimes we get lucky and then other times...
