    tyre pressures beach

    Coming from 265/75/16 tyres on my D2, I am a little unsure of what tyre pressures I should get down to on my new 255/55/19's ... in soft beach sand safely..

    For a day's driving/playing, 16 to 18 psi, depending on the tyre. And drive carefully over rocks!

    Cheers,

    Been down to 10-12 psi on them to get up the dunes in the Warren River area. Had no problems with that on the sand itself but found I did need to air up immediately (~18psi) after getting off the dunes and on to the tracks leading away from the dunes otherwise began accumulating minor rim and side wall damage over time.

    Every D4 or D3 that I have helped to rescue in beach sand (including mine) did not let their tyres down. As Gordon says, 16 to 18 always gets them going with little problem. At worst, use rock crawl (as well as lower pressures) to get maximum traction and diff locking and you will crawl out of almost any bog in sand. Then change back to sand mode.

    I understand the lower the better and this all comes down to experimenting and getting to know what works for you and your vehicle in a particular scenario, but if there was a constant mix of beach sand and rock/gravel, would 20-22 or even higher to 22-24 if you were nicking in and out of beach coves with more rock/gravel between; would this be close to as good, giving more protection for rocks and less hassle not inflating/deflating?
    Cheers, Mungus.

    I had my stock tyres down to 20psi for the trip to West Cape Howe,it blitzed it with 4 adults onboard.There was only one place I needed to take a few re-attempts,it was soft deep sand.Simply backed up a couple of times to get enough room to launch into space,my D2 couldnt accelerate like that in soft sand.Prehaps a few psi lower and I wouldnt have struggled at all.
