Bad wreck

So many crashes occur because of tire failure. Most times the tire is so disintegrated that cause of failure cannot be determined. I'll again make the pitch for TPMS units. Unlike our cars, most every trip in an RV is for a long distance allowing a picked up nail to slow leak the tire to the danger point where it overheats and flies apart. In your car, you'd just come back out of work to find a flat tire. The heavy duty power steering boxes on today's RVs can mask the 'feel' of a low tire on the front and a dual tire that leaks down and fails can sometimes take the other tire with it when it transfers the load it was carrying to the remaining tire. A TPMS isn't going to stop all failures but it will give you a warning of a low tire and THAT will stop a lot of blown apart tires.
