How much air pressure do you guys keep in your tires when running them on the road? I have 35x12.50's Pro-Comp Mud Terrains and was just wondering what I should be keeping them at to get the best wear when they are used on the road.
Im running 25 psi with 285s on a 8" wheels, Id think if youve got 10 wheels you could run around 30, but if youve got 8s then somewhere in the around the neigbor hood of 25 should work alright, Ive got mine at 25 so the tread runs flat, do the chalk test and see were there wearing if the centers wearing more then air down, air up for the oppisote.

It all depends on what kind of vehicle they are on, how much does it usually weigh, what load rating are the tires, what size rim are you running, etc.
For best tread wear you want to have the entire tread width contacting the ground. You can do that by doing the chalk test. Take some chalk and draw a line across the tread of your tire. Drive it forward for like a thousand feet. Don't do corners or drive through mud/water/dirt/anything other than dry pavement. If the outer parts of the line are worn off, but the center is still there, you need to add air. Inner part is gone, but the outer parts of the line are still there, you need to let some air out. Optimum is the entire line is gone.
