Proper Air Pressure for Off-Road Trails

[jdotlim]

This will be my first time I will air down my tires. First time I hit the trails, I did not do it, and I found out the hard way why I felt every bump and almost got stuck. Just wondering what the proper air pressure for dirt trails, and some rock trails. This is no rock climb, just trails that will have small rocks I would have to drive over. I was thinking 18-20PSI, I drive 38PSI daily.

Wheel and Tire Set Up:
2016 4Runner Trail Edition Wheels on 265/70 E-Load BFG KO2

I air down to 20psi whenever I'm out on the trails. Make sure you have an air compressor or onboard co2 to air back up after

Thanks! Yeah, I am buying a compressor on Amazon this week.

I air down to 20psi with great traction. Wheeled at cleghorn, pilot rock, calico and apple valley.

I air down to 18-15 unless I am stuck, then I go to around 10 or 7. But this is with real beadlocks. I don't think I ever went under 20 with normal rims.

18-20 sounds pretty good for that size of tire, and terrain.
you could probably go a bit lower if it was needed, but you wouldn't want to do any high speed stuff, as the chance of rolling the bead off the rim would be higher.

once you get a good compressor, you can play around with pressures. you will find what works best, and when. because the terrain will dictate what pressure you run per each tire/wheel/vehicle combination.

I like 20 psi on my BFG 33's on the '94. Seems to smooth things out pretty well but not so soft as to worry about blowing a bead. I ran them that way for 180 miles in Canyonlands last month.

I have a VIAIR onboard compressor (200C) that works great.

I used to do ice racing at 10-12 psi. You are not going to throw a bead at that pressure. It just depends on the terrain. Dunes or swamp? 10-15 psi. Rocky stuff? Stay a little higher to protect the sidewalls.

I would also recommend 20psi for general offroad situations. 10-15 psi for real sandy, beach driving.
