Both my previous 2005 and new 2011 call for 70 psi front, 65 psi on the rear duals. There isn't much room for putting larger tires on the duals, so your best bet would be to go back to the OEM size on the rear because if you're touching or very close you're looking for trouble. I did put a larger tire on the front of the 2005, think it was a 245/75, had the same OD as the 215/85 on the rear so it worked with the 4x4.
