how low is low PSI?
 

How low is low PSI, I drop mine to 20psi (31 10.5 on 8" wheel), but how low
can you go before you have trouble with ruber coming off wheel?
Does the tire and wheel size matter when you answer this question?

Thanks,

I could swear the manual for my TJ said it was okay to go down to 15psi in
sand but not lower.

I have an air compressor and a ratchet strap, so I don't care if the tire
comes off. I routinely air down to 10 pounds, and sometimes go to 8. I have
never rolled a bead.

Re: how low is low PSI?
 

on my TJ, stock tires I dropped to about 10 lbs for snow or sand. 15 for rock. my
33" swampers I usually drop to anywhere between 5-20 depending on what we are doing
for the day and how hard it is and if I have stockers following me - that is, if I
air down at all. If its a newbie run with real easy stuff I dont...it makes it a
little more challenging. =) It really depends on what you are doing and what the
terrain is. ps - not lost a bead yet.

15 psi is fine. I don't think 20 psi is low enough to do much good.

(You can go lower, 12 or even 10, but unless you have a source for air at
trai's end, you will have to limp along the highway verry slowly until you find
some. With 15, you still have to be careful, and you won't want to go far, but
it won't be as squirrely.)

Re: how low is low PSI?
 

I've lost beads at 20 pounds...hitting a huge tree root. How far you can
air down also depends on what kind of vehicle you have and what tires...if
you have a Sammy, for example, and good offroading tires say made by
Interco, you can go to 0. I've run my own Jeep (33" tires mud terrains) on
larger rocks around 12 but normally 15-20 for most trails depending on the
trail.
