Saving a cupped snow tire 200

Cupping and overinflation wear are different. Cupping is from bad shocks not damping the bounding of the wheel induced from the road and exacerbated by the springs. Overinflation wear is pretty much what you describe.

Start with door pressure. increase inflation in 5# increments until you find one that offers the best compromise (for you) between comfort and road-holding. Typically sidewall pressure is for the maximum load condition (hah, like you drive a 8000# Volvo!). Tire salesmen like to say to inflate to max sidewall pressure but it is UNTRUE. It would say "inflate to XXpsi" instead of "max inflation pressure XXpsi" if it were any sort of gospel.

If the difference in wear is on the order of 2/32" then I'd lower the pressure all the way down to what your sticker says and drive it awhile that way.

Mike!
