Ok, I know there's a lot of variables involved, but what are some general rules of thumb you guys follow for airing down? I understand the concepts, but have heard conflicting information for various terrians. I'll always be running MTs, so what kind of psi's are ideal in snow, mud, sand, rocks?

Keep - keep one thing in mind - the ability to air back up is key if you take too much out. On my swampers, I usually go to about 12 psi, but last weekend when trying a nasty obstacle I aired down to 8 psi when I got to the ledge. I have internal beadlocks and new I was risking a rim, but wanted to get up it. .... I didn't though :slap:

IMO, air down to what you feel comfortable with and you can always let some more out as you go.

I generally run the MT's at either 12psi or 15 psi for most trails - sand / rock / mud. Occasionally down to 10psi for snow / rocks - terrain dependent.

Others might disagree, but it is also dependent upon rim width, tire width, truck weight, etc.

Purchase beadlocks - and you can run with almost no air pressure.

Always run 48psi in the FZJ80R except in Sand, When I dropped to 30psi - Was incredible scary driving to the Service Station to reinflate.
