new to sand driving

Unread post by 953 » September 14th, 2016, 6:37 pm

Plenty of experience 4wdrivng but virtually non on sand.
20yrs ago hired a troopy on Fraser island.
Anyhow, off to robe this W/end to drive & fish.
Obviously, deflate to about 20psi, roll to a stop where appropriate, bit of momentum on the dunes, H orL range ? what else ???
Cheers Dean.

Probably worth having a read of all these threads about Sand Driving here in this section already. ;)

There's probably a few more worth reading with 'Beach Driving' in the title too! ;)

Depending on your tyres, in really soft sand, you can go as low as 9 psi in a pinch. You do risk popping a tyre off a rim BUT sometimes that is the difference between getting out or not -specially in steep soft sand. 12PSi is safer - but 9PSI makes a huge difference when the chips are down.
Also try and stay away from winter beaches that are eroding beaches and very soft.
Low Range with lots of rpms is your best bet when the going gets tough.

^^ If going low means saving the vehicle from a rising tide, in a pinch you can go to ZERO psi!! :eek:

If dropping your tyre pressures to zero psi & being very gentle on the throttle & steering gets you up above the high tide line, then surely even if it costs you a set of new tyres you've still gotta be ahead of losing the entire vehicle & it's contents?! And most good quality LT tyres (that aren't 60 or less low profile 'rubbish for 4WD'ing' tyres!) will handle a few metres of running zero pressure in them when on soft sand; a few metres to get up/off the boggy sand is generally all it really takes, altho running too far with no pressure in your tyres can damage the inside of the tyre due to the rim scoring the under/inside of the tread section, & that's way more likely with lower profile tyres - they just don't have the sidewall height to avoid pinching or scoring things as the pressure drops!! But for most (65 profile & up) tyres, the lower you drop your pressures, the bigger the footprint that the vehicle load is spread over - at zero psi the footprint is usually massive, & if you effectively idle out so you don't spin the rim inside the tyre or pinch anything in there too much, you can often walk up & out of an impossibly soft beach bog that even a well executed snatch recovery wouldn't save you from!!

But you're right Shan, generally you don't want to go too much below 12-15psi or so, but for fairly short & slow sections of soft sand, paying a lot of attention to being gentle on all control inputs (especially steering!) going lower is not to be sneezed at!! :thumb:

Still, this has all been covered at some length in the earlier threads & their posts ;) Lotsa great tips & techniques in there; & 953, there's always people around if your reading raises any further questions. ;)
