I have used old second=hand sets of tires (from a friend! on my 2002s!) and they all threw the tread sooner or later.
I think, at least for older tires, changing the direction of rotation is wrong, and the tires seem to take a "set" in one direction which they do not appreciate changing.
Others may have different experiences, but 3 of the last set of 4 second hand tires (from a friend! on my 2002!) threw the tread within a few months of each other.
