This is exactly what I've been told by so many people in the tire/wheel business. I was told that the maximum weight specification of the wheel has no bearing on the maximum psi of the tire. I know that you can relate weight to load range on a tire, but there is no way to relate psi to load range on a tire. Granted, everybody expects a load range E tire to be inflated to 80 psi and. Load range D tire to be inflated to about 65 psi, but as far as I have found out, the wheel really doesn't care what the psi is as long as the weight limit is not exceeded.
Isn't there some sort of government standard for the maximum psi a tire can be inflated to on a particular wheel?
