What vehicle? Are we talking about going out in the dunes or pulling into camp? What tires? Too many variables to make a blanket statement here. In my Raptor to go out in the dunes, 13 psi with Method beadgrips with 37's. My F350 pulling into Gordon's with a 30' enclosed trailer, 20'ish on 37's. SXS out in the dunes, 8 with beadlocks. Hard pack SXS trail cruising, 8-10 with 33's or 35's on the pro r. SXS hardpack hauling azz, 15'ish. Funco gen 4 LS3, 12'ish front, 10 rear. Always a little less if the sand is wet. :ez:
