How low can you go??

[XJourney]

How low of PSI can I get away with on deep snow? (8psi?) no sharp turns and no big bumps? Snow run Style?

Tire info 265/75/r16 (31.5x10.5) Interco Truxus on stock cherokee 16"x7" wheels

I searched and only could fine street PSI

TIA

i'd say 5. last run I did my 35x12.50s to 6 or 7, but they're on 15x10s. I'm planning on getting 15x8s in the next year, then I will go to 4 or 5.

I woud think 15-18 PSI would be safe. You could go lower but I wouldn;t.

with 35s no bead locks on 10 inch rims I ran 7 Lbs with no problems. I would say it depends on what tire you are running. The harder the tire the more you could let out..

I have ran my 33" MTR's at 3-5, Take it slow and no wheel spin you can float pretty good. Just pack as you go.

why not?

u might get a flat spot duh :)

all depends on the conditions 10-15 is usually good an if u find u have real stiff tires u may want to let out more. if your running on flat snow with now power sliding or spinouts i would say even lower than 10 if your out to have a fun time whipping around then lean more to the 15lb side of things.

you guys saying 15 have never been snow wheelin, have you?

32" Swamper radials on TJ. I normally run 10-12 on woods trails to maintain some clearance. But in snow, normally down to 5-6 psi. The flotation makes up for the loss of ground clearance.

[XJourney]

So 8 psi if I wanted to be conservitive and 3 psi if I want to practice seating the bead. :wierd:

I ran 12 psi last time and wasn't sure how far I could push it.

Yea I like to float not dig, now if I could figure out a good way to get the jeep to idle at 1000 rpms in drive, I could get out and walk ahead and check around the corner :laugh3:

Thanks guys

Get lots of snow in Florida?

I run 19 on the street with my 36's. I run anywhere from 5-10lbs on when I'm wheelin on 15"X10" wheels and I have only lost a bead once and that was from charging up a muddy hill and getting mud in the beads. Just take it down to around 10 and go lower or higher depending on how it behaves. You usually just have to figure it out through experience.

My only direct experience is with the Swamper radials I'm running, but it seems to me a softer tire will allow lower pressures before breaking the bead. I can easily run 10 psi and climb trees which causes the opposite rr. tire to be pulled inward from the wheel till the wheel is just about touching the ground and sidewall is on the ground without breaking a bead. I have yet to unseat a bead. At the same time, others in my club w/ similar weight Jeeps running say Boggers or bias TSL's will unseat beads regularly at teh same psi. I think the softer sidewalls allow the tire to sideslip in this extreme condition rather than pushing the bead off the wheel.
