Question Off Roading Tire Pressure

When I do some serious off-roadin', I take my tire pressure down to bout 20 PSI or so. What is a good pressure for any kind of off roading, rock climbing etc...

I have an 09' Wrangler Rubicon with 17"Rims & 32" tires.

Come on out to badlands with us and I air down to 8 psi - once you get south of 14 psi you will learn what grip is off road . I am not running beadlocks either- I will post a pic to show you how much my tires bludge and wrap at 8 psi.

You really can't see it here but I am at 8-10psi

If you haven't gotten more out of the insurance company than you deserve, then you haven't screwed them nearly as much as they have been screwing you for the past xx years.

on the street i run 25-30psi. trail riding or muddin, sometimes i wont air down at all. sometimes i'll go 15-20. now slippery hills and rocks, off-camber stuff or alot of debris i'll run low, like 10ish. trails i've never been on i will air down to 10ish as well.

alot depends on vehicle weight, tires, and trail conditions. i'm lazy so 75% of the time i don't even bother airing down or even disconnecting my anti-sway bar unless things start giving me trouble. i don't have any bead locks either.

I run 35's with 28 psi on the street and air down to 10-12 psi depending on what we're doing.

The guys I run with seem to think that it's too much air, but with the tires I have it works well.
They usually go with 8 but for me that seems a little low.

No beadlocks here either.
06 Rubi with some sort of double ended, chrome knobbed, cross threaded, infinitely adjustable, frequently breakable, worn out flammywhammers zip tied onto it.
It used to be a jeep thing... til that sh!t broke!

I run 28psi in my Hankooks, I DON"T air down if it's just backroads and light rocks/hills

I will air down to 8-12 psi if it's shale/snow/hills and pulling the trailer

when i didnt have beadlocks i aired down to 10 psi or around it. (8-12) but tried not to go below 10 if i could just-in-case much less and you might blow a bead (which isnt all bad but you have to reinflate to set the bead and if it gets too dirty then taking it off when you get some to clean it out... ) anyways now that i have beadlocks, i air down to about 4 psi

10 to 12 psi. Haven't ever had a problem (except being overcome by the awesomeness of all that grip!).

FYI, one of the bad things about airing down-(needlessly) is you will lose 2/4" of ground clearance and if you're full skided, I guess thats OK, but

When I had my tire year supplied them, but spensive now for big tires

I've got one, but I haven't blown any beads for years and they can be a lifesaver in good/bad weather--zip-zip, tires inflated-course you need an air supply (OBA, compressor) !!!

Thumbs up

Fantastic!! You guys are always so helpful. I think next weekend when I head to the marshlands, I'll drop it down to about 12-14 and see how much more traction I gain. I'll try and get some pictures and post them on the Trail Pics area.

One thing to consider is if you don't have an air source or one close to the trail to air back up.. and you have a long drive may not want to go below 15.
