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.
