I can't make comparisons because I like the way my KM2s work so well I'll not change. If they would still make the KM1 that is what would be on it, If I didn't offroad it as much it would prolly still have BFGs on it but itwould be ATs, or maybe I would look at the newer design they came out with. Can't remember it's name.
I think I might have a thing for BFG tire's They are on my cars a lot also.
