Buy new tires, instead of an insurance policy. Sell the take offs to a local trucker. They like them for trailers. 125$ EACH is realistic. All you have is TIME. Use it. The tire retailers know where/who the truckers are, that are always looking for those take offs.
I would run 100 steer, 90 drive, and 80 for the tag for your trip from SLC to Fl. OR weigh the coach and go from there. Over inflation is simply that.
