Mind you, any appreciable deterioration in tyre life would make even 8% uneconomical for me.
Higher inflation pressures reduce wear by reducing deflection of the material and thus reducing frictional heating and degredation.

The downsides to higher inflation pressures are a harsher ride, obviously, and slightly less ulttimate grip.
