I run 70 psi all around. Without going out and digging out old paperwork, I think actual weight calls for 65 psi but a 5 psi safety margin makes me feel better.
We have a state scale about a mile from the house and when the cops aren't using it they leave it on so anybody can weigh their rigs.
We seem to carry enough junk that we run on the heavy side so it is best to actually weigh your rig to be sure.
