AT4 Offroad Tire Pressure

[geobob]

New to GMC Sierra AT4 trucks. What are your recommendations on running stock Goodyear Wrangler Duratrac tires/wheels in off-road conditions, mostly sand (20 to 30mpr) to slower speed rock trails? I'm used to running Jeeps at about 20 to 25 psi, but the heavier truck I'm concerned with bead loss.

Appreciate your input and experiences.
