We bought a 2010 F53 with original tires and took off on a 2k mile round trip. Had an inside dual blowout. No damage to the MH. Pulled into a nearby rest stop and called Roadside Assist. We had a spare on board and were back moving in less than an hour. Those miles were the last that set of tires saw. There was some minor cracking in the base of the tread grooves.
If youk now the history, and upkeep (air pressure) of your tires from day one, (I DID NOT) I believe it can be a totally different deal. Close inspection and proper air pressure and I'm looking to get 10 yras. from my new Toyos.
