I would personally run 30 max. In my 33's i run 27ish on the road if you go higher well you get a really rough ride. On the trail I run around 10 psi with my 33's. Cory you can easy drop down to 14 psi for the trail.

If you haven't gotten more out of the insurance company than you deserve, then you haven't screwed them nearly as much as they have been screwing you for the past xx years.
30 to 31 psi (max) is what I'd run for 31" tires. Run 31 if your Jeep is fully loaded, 29-30 psi for normal 1-2 people load. You can safely run 12-13 psi on the trail so long as you're not running them on a 15x10 wheel.

If you rub a thick chalk line across your tire and drive down the street, you can tell how it's going to wear at a given pressure. If it's worn only in the middle, drop your pressure a little. It it's on the outsides, raise it.
