Maybe there's a lesson here about tires?

My kid runs a trailer shop and tells me some pretty goods stories from time to time. He went in Saturday to do catch up on some paper work. He's not open Saturdays, but pulls into his shop driveway and there is a large trailer parked in middle of his driveway, locked up and nobody is there . A note is wrapped around the hitch. He calls the number and the guy says a tire blew and ripped off his skirting. He tells the guy he doesn't do RV body work repairs and come move your RV. The guy is 2 hours away and also tells my son his tow vehicle (pick up) broke down when he was going back home and will let him know when his dealer gets it fixed. MY kid tells him he's going to cut the hitch lock and move it out of the driveway. Then the guy says "he has no idea why the tire blew, this is second time a tire blew and ripped of the my skirting. The first time the tire blew and ripped off the skirting I had recommended air pressure. But this second time I only put 1/2 of what recommended tire pressure as a pre-caution because he didn't want that much air pressure in a tire so close to his new skirting".
