My most rugged off roading is done in an area of granite lava flows. This makes for a lot of slick rock, large rocks, ledges, and "potholes" in solid granite. Most if not all of these obstacles are height driven, so the more clearance, the better.

My original 4X4 was a Chevy S-10. The only lift I had on it was larger tires. My uneducated logic was, why would I air down? Airing down could make me lose a small amount of height, plus make me sink even more coming off an obstacle as the tire compressed. Now that I have my Commander, I am surrounded by those who air down for 4 wheeling.

So my questions to the forum are: Do you air down, if so how much, and what (besides ride comfort) are the ups and downs?
