It really pays to keep good tires on trailers.
It's been a long while ago but a guy in a motorhome was pulling a trailer of some kind, maybe a boat. He was north of Boise on a state highway in a national forest. The forest was super dry at the time. He blew a tire on the trailer but couldn't see it in his mirrors so he just kept driving. The bare wheel was throwing sparks. Before someone could flag him down, he'd started a 3 mile long forest fire. It turned into one of the big ones that took weeks to put out.
You guys in SW Idaho might remember that one. It was in Banks canyon at least 20 years ago.
