1990 GMC Jimmy-Sand Dunes Tire Pressure?

[scoutcamper]

Hey All,

So I just bought a 1990 Jimmy, 4" lift 33" Big-O All Terrains, 350 TBI. My family does a trip to the Horsefal Dunes in Coos Bay every year, leaving this week to go up there! I plan to take the Jimmy this year to play. My real question is what tire pressure should I be running?

Searching around here I see everything from 3PSI to 35PSI. I currently run at 25PSI on the road. I will have an air compressor with me, so I can adjust on the fly. I will have a RZR800 and a few LTZ400's, but I doubt all of those combined could drag the jimmy out if it gets stuck, so trying to avoid that

7-10 PSI is a good start. That's what I run here at Silver Lake.

Without beadlock wheels i wouldn't go under 10.
Get a winch because your going to get stuck and your right they are not going to pull you out very well.
then before your trip next year get a set of lockers, that way you can get really stuck
