The weight of the rig will effect how much air is needed to support it.
A 3000lb rig with the same amount of sidewall bulge will need about half the psi as a 6000lb rig will.
Measure the height of you sidewall at street psi.
Divide by two.
Deflate one rear and one front till there almost touching the ground.
Re inflate the tires until you get half the height back.
The fronts will require more psi then the rear. On a diesel it might be as high as 50% more.
I run 18 psi on and off road, I`v chaulked my tires and 25psi rear and 28psi front is my sweatspot. By running 18psi I can quickly jump up 10psi for a long highway trip or air down 10psi for the trail if needed. The good thing about doing this is when you see that trail off the side of the road that looks interesting, you can just do it.
I rarely air down and run 18psi on all trails, if by chance I need that extra footprint then I will run 8psi rear and 10psi front.
I also run what I would call a Redneck Beadlock, a 12.5'' wide tire on a 15'' by 7.5'' wide rim.
So that`s my problem, Every time Tootsie`s spotting I usually have to pull cable or I end up breaking something.
Nothing to big though, as I`m thinking she just wants a nap and not a long walk home.
