in europe they say 2.0bar front and back unloaded on the 18 inch wheels. (2017 model). they look very low to me and mpg chagnes quite a bit. i used 2.4 bar now.

Sometimes I go down to 10psi on sand.

I run 285 70 17 and I only once have knocked the bead off at 10psi but that was due to being an idiot.

The 4 psi rule is a good one to look up

35-45 psi should be fine on highway depending on your load and comfort needs
I run the below with my 285/75/16 BFGs
32-38psi off road depending on terrain and load
20-25psi on sand down to 16 if really needed

Thanks for the suggestions, doesn't 32-38psi off road seem a little high I normally run 24PSI up front and 26psi in the rear fully loaded on dirt and gravel tracks. With my vehicle mods & accessories my current vehicle gross weighs is 3250KG and have a 3" suspension lift.

Good to know, normally 15 to 20 psi is good for sand where I'm at.

Depends what sort of track it is. On hard/compact well formed tracks 38 is fine. Once they start getting corrugated, loose, wet, slippery or uncomfortably bumpy you will need to go down.
The 4psi rule can be a good indicator of correct pressure. Take cold pressure temp, drive for 20-30 minutes, take pressures again. They should go up by 4 psi. Anything less can indicate cold pressure was too high, anything over 4psi increase can indicate starting pressure was too low/ side walls flexing too much generating excess heat
Can be a matter of trial and error, taking all variables into consideration + personal preference
