Silly question? Does running higher PSI cause more wear-and-tear on suspension?

[matti]

I increased the PSI in my tires a bit and, of course, the ride feels a bit more harsh. That doesn't bother me. However, I started to wonder if the stiffer ride puts more wear-and-tear on the suspension components? Any thoughts? If so, is the increased wear-and-tear anything to be at all concerned about? Thanks.
