40psig, front and rear. Someone on FSB has a picture of a FSB certification sticker with this exact pressure on it for 31x10.5-15's.

I run 35-40 psi on the road. I have never aired them down offroad, there isn't enough clearance under the axles to air down.

I run 35 psi in mine all the time. I don't do any off-roading, strictly highway.

The tire will tell you
I think he meant that on more then one level. If you've got an appropriate tire for the wheel, running it at max psi will leave you with probably the best tread life...

Not only that, but visually looking at or measuring the tread in the center versus the edges will let you know after a few thousand miles whether or not you need to up or down the pressure. If you're chewing up tread in the center, you should probably drop the pressure down for more even wear, and vice versa.

I don't have a picture, but I have that tire size and the actual factory PSI on the door sticker is 32 psi.

35 psi. I never air down for wheeling either. Running a slightly lower PSI really helps with comfort. Truck doesn't rattle as much.
