It will also depend on the tire also. I ran 36x13.50/15 Iroks on 15x10 Daytona rims. I ran between 5-8 psi on the trail. They didn't look like I had aired them down at all. Only time you could tell was when it was strapped on the trailer or when you put the tire against a rock. Then it would wrap and grab. They were bias ply's. A radial will bulge at normal air pressure and look like it is low. Then when you air down they will actually pick up the center of your contact patch. Leaving you riding on a O contacting the ground.
I demonstated this to my buddies when we used to race Mustangs. A properly aired radial will leave a consistant black mark across the section. Too much air and it is dark in the middle light on the edges. The opposite for too low, dark on the edges and light in the middle where it is actually picking up. Not to mention all the racing stipes up and down the road in front of his house.
