I have always removed my wheels and checked the brakes at home after acquiring a trailer, new or used…
Although some tire dealer cross threaded a nut on my van spare rack and then just run it on with an air impact… and when I needed it, I needed a torch to burn it off after the stud began turning instead of loosening…
Naturally this happen along the highway far from home at the beginning of a holiday weekend… Good Sam ERS to the rescue…
BTW: you did say…
“Now I get to go to a local tire store and be told the tire (now to be the spare) isn't repairable!!!!”
