Sand Driving Tyre Pressures

[TheTree]

Hi

I am doing a Sand Driver training course with the RR Club of NSW this Sat on Stockton Beach and have been thinking about tyre pressures.

My question is given the 10PSI difference between front and back on a P38, should I maintain the difference when i deflate?

EG: If I go to 15PSI in the front should I go to 25PSI in the back or is it OK to drop the back pressures to 15PSI as well?

Note to Hoges; I will keep an eye out for the Polo ponies mate

Ive always gone 16psi front and back if im lightly loaded, and 18 if im loaded. 26 would be way to high.

benji,

That's what I was thinking as well, it actually pretty unusual in my experience for the back to be 10PSI more than the front, but I guess in low speed sand driving, it makes no difference whereas on the road, heat buildup etc is an issue

Thanks

Steve,

Wait until Saturday and we will tell you all you need to know, or at least give you some guidance. !!!

I know I will be dropping mine to 16PSI.
It will be interesting to me how my 2002 D2 TD5 auto without CDL will go at Stockton although the sand will be so wet you could probably leave street pressures! LOL
My RRC with the "dreaded" VC had no problem last time I was there , while a RRS had all sorts of trouble until he switched off DSC, and the bloke was a VERY experienced sand driver.

On Stockton, with the 16" P38 rims I would go straight to 16psi. I doubt you will need to go lower, but those rims are the best in the business for holding onto tyres if you do need to go lower.

Unfortunately I also have 18s on my D2, and they are Chinese junk, but I have 2 sets of 16s under the house waiting for tyres which I cannot currently afford.

Yeah 16psi all round and you'll be lapping stocko like a pro.

George,

I am sure you will

Thanks everyone for all the answers

I am sure the P38 on Stockton is going to be a little different from driving my Series One through the Flinders Ranges and across the desert to Lake Eyre... but then that was longer ago than I can remember
