Sand mode, DSC off and 18-20 psi; lower to 16 if necessary; probably could go to as low as 12 in an emergency (stuck) in a straight line - ie sharp turns increases likelihood of tyre coming off rim; use Rock Crawl if you get stuck
The missus and I are heading to Eighty Mile Beach for 5 days and are looking forward to getting the D4 on the sand. My previous D2 had issues with traction control and sand and found ourselves stuck a couple of times on what I thought would be a breeze for it. Obviously the D4 is streaks ahead of the D2 but what i was wondering is there any D4 specific things i should take note on with the D4 on sand?
And what is the minimum tyre pressure that is safe to go down to with the standard 255/55/r19's?

And don't forget to turn DSC back off if you change any TR setting.

Where is the soft sand on eighty mile beach ?
Wallal downs.....two wheel drive. And two wheel drive in a few other places. Have been there a number of times, but quite possible I missed the soft stuff if I went at a different time of the year. Have even towed our camper along one stretch for about 10kms.
As mentioned earlier, 16 is a good pressure with 19's provided it is soft enough to warrant it.
I have been down to 12 at calcup, but had dsc off and low range to get over the last dune due to the electronics deciding I was pushing her too hard.

Hmm - DSC seems to be a bit of black magic so I would not disagree but then would not agree based on my own experiences.
One week after getting my car ended up here and was surprised that I could not get out.
I was crossed up and traction control was not kicking in - trying different TR settings - traction control was not kicking in because engine revs would not go above 2500rpm so couldn't get a wheel to spin fast enough - I later found out that DSC was cutting engine power at 2500rpm. If I had DSC off I would most likely have driven out. Instead I had to get the Freelander to pull me out - after I was out the Freelander had no issues driving through with less ground clearance as its traction control worked once revs got up a bit.
I have found DSC works well on most conditions (detects deflating tyres pretty well) and I would leave it on in most conditions offroad and only turn it off for difficult conditions. It may stop a roll over if swerving on the beach to miss something.

Height and Tires mate- it is entirely possible to get stuck on wet grass. DSC is only one reason you could not extract yourself once stuck. Road or even AT tires in deep mud especially if you have your tummy sitting on the deck taking a lot of weight and traction off your tires. Avon River descent in WA had a farmer on a tractor making a killing towing hundreds of cars and even some 4wds he allowed to park for free in his nice grassy paddock at $50 per tow

SSSSSSSSSShhhhhhhhhh mate my swimbo likes Freelanders and I like my D3
Back on topic
Sand driving is lower tire pressure and momentum especially if in soft sand. Do not dig a hole when starting off and do not stop in really soft stuff. DSC off, tires down and ride height at as high as you can go before you start playing.

I like the momentum part in mud as well
