See, that's the thing. In 45 years of CO 4-wheeling and hunting I've never had a problem with comfort, traction, or had a flat. Until it's a problem, I don't know what I'm missing, I guess.
I went on a buddy's elk hunt last year. We were there 10 days with his Jeep Cherokee and my old Toyota. We drove both everywhere because his dad was with him and he doesn't have a rear seat. He aired down when we got there, and then seemed to take 45min to an hour to air back up before we left. It didn't seem to make any difference for anywhere we went.

But I'll give it a shot the next time I'm up there. The problem is.......some of the places I hunt can be 20-50 miles away from camp on paved 65mph roads. Don't think I want to be aired down when I jump on one of those roads.
