Tire psi suggestions

Upcoming camp out/ run is embedded goat head size rocks, ultimate rattle run (Goose lake, Beartooth mountains, MT) 285/75 16 D90 with full rack and camp gear. Not too concerned about slipping beads, just want to dampen bumps.

Appreciate any thoughts

Are your tires "E" rated (10 ply)?
BFG says to go no lower than 15psi at a max speed of 15mph for their KO's & MT's.
IF you are "E" rated, I'd say for safety sake to go no lower than 20.

I've always heard 22 was the magic number. That should be fairly cushy.

I usually do 18 to 15 (15 most) on semi rocky stuff. Lower on muddy forest trails. Don't do less than 12 w/o some sort of bead retention.

I do 14-16 psi offroad but I keep it below 30 mph.
Back when I had bead locks I'd do 8-9psi.
Amazing difference.

Love beartooth pass. My cousin was married there at the old scout camp and pavilion. Just beautiful.

X2, though I was on 33x12.5x15 - now 35s. Ride and traction great, but cornering is interesting without swaybars. Never have had a bead roll or burp, loaded, crawling or highway. 20 would be an improvement on the trail described but 15 would be cushy especially when loaded.

I usually air down to 15 or so and will drive up to 60 for short periods. FWIW, customer cars come in all the time with under 20 psi in their tires and I know they are driving faster than 30 mph.

I know one NYC Boost club that ran 100psi in his tires because that's what it said on the casing.

Thanks!

15 psi softened the blow and made a good combo for the remains snow drifts. The pride of being the first and only one in this year faded with the sunlight as I realized just how remote I was, with no fires, cell service, etc in the heart of bear country. At least a roof top tent doesn't feel so much as a bear "candy wrapper".

Thanks again
