I agree with trikkonceptz except for one point. (Note* I have never run vehicles at the stock pressure, always above, )

Two things I have noticed
some tires seem to last forever but then end up with uneven wear far past their prime
other tires run above their rating get sidewall rot earlier than they should

So its a mixed bag whether or not you will actually get better tire life from overinflation. On my Suburbans its tends to be the opposite, on lighter vehicles it seems to extend life.

Not sure if there is much that can be done for sidewall cracking but that is the only real failure I have ever gotten on tires in that the side wall blows or developes a slow leak.
