DBoat Aired down to 11 psi and what a difference. Thank you all for the advice. As an aside, used my new CO2 setup to air back up. All Incan say is W O W. this is the setup for the truly impatient. Took maybe a minute per wheel.

DBoat Guess I am going to go to 10 psi and give it a try.. unless I hear from Jerry otherwise..

You should be fine at 12 psi or thereabouts. Some go down a little further with a 10" wide wheel but...

GoldenSahara00 12 is good but it depends on the tire compound. My duratracs at 12 and MTR at 8 behave about the same.

DBoat Thanks for the great responses.. I will look at the width of my 17" rims and get the exact tire size tonight and post up.. however, it looks like I am heading to 10 lbs for this excursion.
on a related note, my buddy Mike and I installed the holders for the CO2 tank last night in the tub of the Jeep. They should work well..

amiller Generally between 8 and 12 psi. is where I play

Michigunman Not knowing your exact specs, I'm running similar. 285/70x17 (33x11.5) tires on 8" wide rims. I had been airing down to 12 psi. I recently started going down to 10 with noticeable improvements. My tires were barely squatting at 12. Never burped any air or had any issues.

Attached is a picture from this past weekend.

1ofakind i have 33x12.50 on my 15x8 wheels, typically air down to 6-8psi in the snow with zero trouble. 10 would work also

Sherpa Like Jerry, I am also running 35x12.50 tires on 15x8 non-beadlock wheels. I regularly air down to 12 psi front, 10 psi rear and have no issues whatsoever off road. I leave a couple extra pounds up front since (in my mind, anyway) a tire that steers is more likely to unseat... though I'm pretty confident I could drop another two pounds without worry.

Jerry Bransford Until you get below 15 psi, you're not really airing down for offroading. You can safely air down to 11-12 psi. But part of that depends on your wheel width... you can safely air down to lower air pressures before it may unseat with a 15x8 wheel than you can with a 15x10 wheel.

Even before I got my beadlock wheels I would air my 35x12.50 tires on 15x8 wheels down to 7-8 psi for tougher trails & they never unseated.

I am sure there are some threads on this... but..

I have 17" wheels with 33" tires.. just need some recommendations on how far to air down the tires for some crawling. I run 30 psi on the street..

Is 17 psi low enough? 12 psi? Post up..
