Reply With QuoteI ran 18psi on my 19's on Goolwa beach with no issues at all and there was plenty of very soft sand; so with 20's maybe try 20psi and see how you go? Lets see what everyone else thinks....!

Anyone have an opinion on how I would go on sand with stock 20" tyres????
Anyone actually tried??
I've got some 18" rims coming but in the mean time there is a chance I may want to venture onto the beach over xmas.
There is not much side wall there to bulge out at lower pressure and I don't fancy being stuck. What pressure would I run???
(I remember my D1 would often cease to proceed with road pressure in the tyres. I think I used to run them at 16 or 18psi on the beach?? )

What size/make of tyre are you running on the 20" rims?

Those aren't too bad as far as 20" tyres go. Try 20psi, and if you below be very careful about where you drive so as not to damage the rims. The real problem 20" are the RRS's 275/40/20 which are wider, shorter sidewall and thinner construction. However, a switch to a higher-profile tyre would be a good move. Lighten the car as much as you can.
Let's just clarify....
Sidewalk bulge is NOT the desired result. Lengthening is...

Im not to keen on sidewalk bulge either Tombie2 but I know what you mean

any one been to mutton bird beach and dingoes, down in Albany, WA? What pressure did you run with 18'' rims on your disco? i let tyres down to 18 pound and it was not enough. I had a mate to snatch me out a few times and as long as i kept moving it was fine.
Next day i went to bluff creek and let tyres down to 12 pound (much more then is needed for Bluff Creek) and i wasnt real comfortable with the lack of tyre wall, you could really feel at times to be driving on the rims. What are your experiences?

SubscriberYES!!!!!
So true. Picture pushing a light 1.5 foot high log along the beach - not much fun cause it has the sand wedge all down its length and you are attempting to overcome that wedge and doing so with an acute attack angle to the sand flat just ahead of the wedge of sand. Now picture the log cut into a slice 4 inches wide but also taller and with greater diameter - picture how small the wedge now is to overcome and that the approach angle of the wood is now shallower with much better change of overcoming the wedge. Its an extreme example, but beyond doubt now that length is what you are after on the beach more so than width.

We normally use 16psi for softer beach driving - noting that we take it easy (30 ~ 40 kph max) and generally don't do more than 10km at a time. It makes quite a difference over driving at 18psi. Very soft sand/seaweed I'll drop to 10psi, but then re-inflate immediately after. That's with 255/55R19's, and at that lower pressure you do have to be careful of rim damage.
