It could have just been a one time contact on a rought road.
Other picture that shows the tire damage (blue sidewall) is not from short contacts due to bouncing on rough road but from rubbing at speed.
Something is allowing the axle to move side to side or you have low inflation in the tire that allows it to have the top move inward when the bottom moves outward in turns. Static with correct inflation you should have 1" clearance as tires will deflect that much with high side loading seen on trailer application.
Tires rubbing on frame are not a tire failure but a failure of some other part as tires are not designed to rub against vehicle parts.
