Have you ever replaced your struts? If they are not bad, it sounds like an alignment issue. Generally tire pressure will wear tires in one of three ways.

1) even.
2) on the outer edges (underinflation)
3) Inside (overinflation)

Tire pressure should not cause the tires to wear unevenly, just improperly. This is the case as long as pressures are even from side to side.
