How low do you go?
 

How low of tire pressure do you run? Along with the pressure, what size/brand tire and what size/material wheel? Last, but not least. Have you lost a bead?

I ran 12 psi warm with 31x10.5r15 bfg ko2 on 15x8 alloys
12 psi warm with 33x10.5r15 bfg ko2 on 15x8 alloys
8 psi warm with 35x12.5r15 Goodyear mtrs on 15x8 alloys

I have not yet lost a bead.
Edited after caged posted. Forgot about the effects of driving heat on tires. I've always driven to the park and aired down.

yeah, with 33's (33x12.5 on 8 inch steelies with 3.75bs) i'm usually around 12, but that's airing down at the trail while the tires are warm. but i've aired down to 8 in the past.
but with my 36 bias iroks on beadlocks, i've aired down to 2 warm which at the end of the day, didn't register on the pressure gauge, just showed 0.

i've never lost a bead.

Thanks for mentioning the warm/cold. Didn't think about that.

35x12.5 on 8" rim,, Im at 20 PSI normal daily driving..(checked with chalk test) has good footprint.
In the winter with snow all over the roads I drop another 5 psi from the 20..
When out wheeling Ive taken them down to 10 PSI..

What kind of tires?

I run 34x10.50x15 super swamper tsl bias ply on 15 x 8 beadlocks and run at 3psi cold offroad and 12-15psi on the road anything over 15psi it rides like a hay wagon
