I know this is an old thread.
A bit of advice from experience...
I have a 2003 Tahoe(~5,000 lbs) with 33" K02's.
There was some discussion about airing down. I think a lot of you guys sound too paranoid!
If I'm driving >100 miles I might go up to mid 30's. Normally I run ~30 psi. I'm not afraid to run 20 psi 20 or 30 miles, and I have already driven about a dozen miles on paved roads in the mid teens. Its a bit mushy and you should double check to make sure they're not melting, but you can certainly do it in a pinch.
For my setup, 20 is fine for gravel and mild trail and I don't need to air up even though I do carry a good compressor.
Mid teens is where my traction and ride really start improving. I think this pic is 15. If its very steep/rocky, 12 does give a traction advantage at the cost of a bit of ground clearance. Under 12 on rocks without beadlocks you should be very careful with tire placement. >12 you shouldn't need to worry unless you have a significantly heavier vehicle with small tires or stretched tires.(rims wider than the factory recommended width for the tire)
I have found that airing down in deep snow (or sand) makes just as much or even more difference in traction than on dirt/rocks. I saw a Silverado not close to making it up a snowy hill with multiple runs at street pressure. Aired down and it literally hardly spun!
I've aired down to 10 in soft snow and it really helps with flotation. I haven't experimented on snow-pack or ice but I think lower pressure is still advantageous at least at low speeds.
I like offroading and talking about offroading so feel free to ask any questions!
