We are heading up to Fraser Island soon with a WK V8 limited with the factory 20" wheels and just wondering what tyre pressure people are dropping to.
Towing a camper trailer as well if that will make a difference.
There isn't a standard recipe for tyre pressures...it will depend on the weather and the sort of sand you are operating in.
Particularly if you are towing anything it will be very important to certainly drop them - start at maybe 20 or 18 BEFORE you get stuck.
What you are trying to do is lengthen the tyre footprint so it sits on the sand not down in it. 16 or even 12 won't be too low if conditions demand and you need to get through a sticky bit.
By just looking at the tyre tracks you leave and the attitude of the tyre on the sand will give you some hints.
Make sure you have a good compressor and that will at least eliminate the temptation to run with them high. Hard tyres in sand equals hard working vehicle.
Once they are lowered treat them with respect - remember side walls are exposed and it will be an expensive lesson to damage a 20". Inland tracks have all sorts of tree roots just waiting to snag side walls.
Enjoy Fraser - it is a great experience - but take it easy.
