tyre pressures beach

[Aaron40]

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..

[gghaggis]

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.

Gordon when are your next courses in Perth?

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?

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:cool::cool::cool::cool:.Prehaps a few psi lower and I wouldnt have struggled at all.

Well yes, there are lots of other scenarios, but the OP was talking about soft beach sand.

I have 18s so you probably need to go lower for 19s, but I have a set of easy downs set at 25 and that's my beach standard and I have never been bogged in my D3 in sand.

The comment about running on sand and the rocky tracks is interesting. We do that all the time including tracks where we can hit 40kph at time down at Beachport. We have never changed tyre pressure from 16 over all that as it is not about the pressure in this situation it is all about the speed you drive at with tyres this low as that is what builds up the temperature

We do this all the way across the Simpson Desert as well and have done for at least the last 20 crossings

Thanks for the info in this thread. I too have gone from D2 to D4.
I've just been playing with my pressures on scorpion 255/55 19 on my 4. 25 seems ok on tracks and I aired down to 17 just to look at the bagging effect and the tyre looks ok for sand but there isn't much rim or sidewall protection for rocks.
