Probably a lot of tires are damaged on turns when people forget about how a trailer, especially a 5er, turns inside the track of the tow vehicle. Jumping or scrubbing curbs, dropping off the edge of culverts, hitting rocks or other barriers off the edge of the roadway, etc. Then the damaged tire comes apart over time. I have seen it happen a lot, and jumped at least a couple of curbs myself before I became more aware of it. First time I was not even aware I was over the curb while pulling into a service station until I happened to see it in my mirror.
I do have a TPMS to let me know of a low tire before it gets destroyed while driving.
