Tire deflation question

I am running 33X10.5X15 BFG Mud Terrains on stock Canyon rims. Most of my off road driving is on pretty smooth terrain but I am starting to hit some trails with more and more rocks. My question is, what is a safe PSI to deflate to? I do have an onboard air compressor so airing back up won't be a problem. Thanks!

I run the same tire (actually KM1s):

On road = 28 psi
Normal dry off roading = 12 psi
Wet and muddy off roading = 10 psi
Snow off roading = 8-10 psi

My wheel is the OEM Gambler wheel.

Agreed & I'll add 5-8 psi on sand.

Bit more pressure on a smaller tire.
