I've had belts come off on three BFG Radial All-Terrains with decent tread but a dozen years old. That was at 70mph. They banged up the fenders pretty bad. Had another old radial come apart on a Taurus, took the tread off right down to the shiny steel belt, that was a handful to get stopped. That was at 75mph.

Even though I'm a tightwad, I'm starting to come around to the idea that old tires will fail for no apparent reason, especially at speed.

But I do hate it when tire shops act like they're doing me a favor to do business with me.
