Off road tire pressure (for rocks)

Shut it fagger!

I ran fins and things with Jerry Seiner Hummer Happenings last month. Left the tires at 35 and didn't have any problems.
This weekend I'll try them at 30psi and see if there's any difference. I'm still running the stock 285's

You will notice a difference in traction and ride.

I like the tires to do half the work of the suspension

Lowering psi on harsh high-speed wash board roads makes a heck of difference too.

I like 18-22, they heat up on the trail. any lower you always risk a slip off the rim. i saw a guy do the lighter fluid trick to put the rubber back on his h1 rim. It was cool.

I have a heavy ratchet strap and a can of brake cleaner if necessary. The compressor is on the truck.

If it does pop a bead it will suck, but shouldn't be anything to start bawlin about. Plenty of high lifts will be along on this trip.

Beebs,

I think stagger lee is OK.

So far he didn't bring much to this discussion, but if I (n)ever wanted an opinion of how the liberal hippy commune community felt about the Bush Administrations handling of foreign policy; he'd be the first deadhead I asked.

Occasionally, threads around here have a way of going straight into the crapper. I was hoping to pull some experience and knowledge out it, before that happened.

I was just pulling off my side rails and noticed my rear diff is wet. Hopefully I can run it to the dealer before work tomarrow.

When I had the tires at 35 the ride was still pretty good offroad. It'll be interesting to feel the difference at 30. I'm not crazy about going any lower, where I'm staying is about 20 miles from Neocon's house.

Hey desert,

I hope everything is fine with your rig. We are planning to run some cool trails. I hope you can still make it. If you are just worried about loaning me your spare tire relax, I'll borrow Neo's.

Stagger,

Have you ever popped a bead? You know that 15-18 is perfect, how? Lower pressure is better for rocks. There are hazards. That's why beadlocks have become so popular off road.

Unless you've gone low enough to pop a bead, I don't think you know the "perfect" answer for the H3. I see the common logic, but it's not so clear for every 4x4, many go as low as they can. Buggies commonly run 3 psi with beadlocks.

Thanks for "dumbing" it down for me.

Wasn't trying o dumb it down chief.
I have popped a bead at 10lbs on my scout. I have popped a bead at 12lbs on rocks in my old FJ80. It depends a lot on the tires. The toyos seem to have a pretty stiff sidewall as well as the goodyear MTRs. BFGs aren't as stiff, and I had super Swampers before and they were like jello. I have not popped a bead on the H3 yet, because I haven't pushed my luck. There is really no perfect pressure. You can pop a bead a 15lbs if you hit an obstacle just right you know? I dont have the knowledge or experience in the H3 as some of the others on here, but I have been off roading my whole life, in multiple rigs and set ups, so I have really just come of with the perfect pressure that works for me and that I feel comfortable with.

I also would rather sacrifice a bit of extra traction by not running really low pressure in order to save me from down time on the trail. Im sure you could go lower then I do and be fine. Eventually I would like to get a set of beadies just for the trail to be used on the H3.

Borrow my spare and it would look like you're driving on one of those donut tires.

Hey F you guys! haha j/k. What, like 4 people gave the right answer of 15-18 lbs depending on tires, so instead of of being a parrot and becoming the 5th douche to give the same answer I smart my a$$ off. Im just here for the entertainment and maybe try and get you to chuckle a bit while youre reading.


So here is a straight answer. Experience comes from equally heavy rigs, Scouts, FJ40s, and FJ80s, as I haven't really rockcrawled the H3, but sand and snow yes. I run 15 -18 lbs on rocks and snow. Loose rocks closer to 18lbs, flat slick rock (Moab Stylie) closer to 15lbs. Slow driving in sand a bit lower, but not usually lower then about 13lbs, and if I'm driving fast in the sand I want it no lower than 15lbs. We have run 10lbs in my brothers prerunner in Glamis, be he has beadlocks so it doesn't matter. Our rigs are pretty heavy so anything lower than 15lbs is pushing your luck I think. Hows that for a recap on the previously already perfect answers given. Thanks for givin me crap guys. Keeps me in line.
