Standard wisdom is 10-15% less than you run on bitumen. Personally I tend to drop a bit more, particularly if heavily corrugated or sandy.
On bitumen I'm running the Toyo's at 40psi. On a dirt road like the Giles-Mulga Park or the Tanami, I'm running at 30-32 on the rears and and 26 on the steers dependent on load. If towing I'll stick a little higher on the rears due to the towbar weight.
Badly corrugated track like the Anne Beadell, Canning or Gunbarrel, I'll be lower again remembering that heat is the trade off. I've also got my shocks tuned down so there is bugger all damper.
