    As low as possible without blowing a bead. /forums/images/graemlins/wink.gif It will depend on your rim width, but just air them down until you get a nice healthy bulge in the sidewall at the ground. The idea is to increase the contact patch so the tire floats.

    Shaggy summed it up.
    Sand?
    If they're 16.5 rims, go like 20psi.
    If they're 15's or 16's try about 10psi and that will make a big difference in traction out in the sand.. /forums/images/graemlins/peace.gif

    I run my 35x 12.50x 15 mud terrains on 15x10 rims at 8psi in the sand. Never blown a bead.

    I used to go to the dunes in Northern Michigan..
    Changing tire pressure didn't change traction much..

    Get ready for some outside tread..wear!!
    I used to round my tires..

    Have Fun!!! Get some AIR!!! /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif

    Hey man I run 8 lbs in the rear 9 or 10 in the front we go to the sand dunes in yuma almost every weekend and this works best for my set-up. smooth ride lots of traction. have'nt popped a bead yet in sand, but have spun the tire on the rim. right out of balance. good luck.

    Maybe Michigan dunes are different. I notice quite a difference in the sand with low pressure.
    I always see people drive down onto the sand at pismo oceano dunes with like 35psi in their tires, even in 4wd they'll start getting stuck and just bury the truck down to the axles. If they stop as soon as they start getting stuck and not going anywhere... and air the tires down to about 14psi the truck pops right out of the hole it just dug itself into. /forums/images/graemlins/thinking.gif /forums/images/graemlins/whistling.gif

    I go to Silver Lake, Michigan and I watch people all the time TRY to climb hills without airing down. They end up burried to there axles.

    I run my BFG Mudders at 8 psi on soft sand and 12-15 psi on wet. I run higher psi on wet to keep from spinning the rim or busting the bead (I busted the bead only once running at 8 psi on wet sand....sucks!

    up at silver lake i run at 10 psi on the 265/75/16s. the tire looks completely flat, i wouldn't wanna run any lower with these tires. i got great traction you must air down for sand, you will get stuck. i dont think there much difference in traction between 8-12.

    my friend on his toyota pickup ran 4 and kept getting stuck, he aired down to 2 and was better so he went down to 1 and did great till he lost a bead and almost rolled his truck.

    hopefully i can go up there on the 4th and be a little taller and bigger/wider tires /forums/images/graemlins/deal.gif

    Ditto. I used to always see this when we used to go to the Outer Banks.

    Then last summer at Sand Dunes Nat'l Monument I saw people doing the same thing. Tearing up the trail. Had to get out and make about 5 trucks air down. Mostly guys in new SUV's with the A/C on of course.

    When I going duning in Glamis, we run about 15lbs, give or take a few. Hugh difference especially with a full trailer and back of the truck loaded. More contact patch better = better traction, more air = get a shovel and tow truck.
