That's what I'm looking for. Since my tires were a bit warm to the touch at the turnoff to Mike's, it would roughly correspond to 100-110*, about 40*
above a nominal 70* starting temp. I like your POV on "not getting stuck" as a priority.

Harald, what would you suggest be the the proper (or safest) tire pressure for navigating the pot hole fields of Catavina?

I would use the lowest speed possible
tire pressure around 50 psi
as you remember, I had already recommended a +10 psi pressure for highway driving

the more you air down, the closer you get to a caterpillar
on some trips I have changed tire pressure 4 or 5 times.
sometimes just for 10 minutes to climb a nasty hill
that means, a serious 4x4 needs a serious air compressor
smart move, by the way, Tom!
State of California wanted to hire me some years back to teach maintenance crews for remote radio sites in 4x4 recovery. I talked them into teaching
not to get stuck. Tire pressure plays a big role in it. We added a few hours of recovery anyway, because it never hurts - but the main thinking has to
be "how can I avoid getting stuck", not "how do I use my winch"

sounds like a two-way tire pressure system would be convenient
anyone use em?

Thanks for sharing that link, Del Mar.
Harald probably has answers for this...
Question: If one tire gets a flat, what stops the air from draining out of all four?
Reading the website: Taking 6 minutes to let the air out for off-roading seems long?
Looks like a kit for Jeeps only?

unless you have portal axles, there is no reliable central air system on the market
the one shown has the lines hanging outside the tires at all times
guess the vendor has never been off-road
