Greg and Russ, do you like the ko2's over the km2's?
I have personally used KM2s, as well as MTRKs on a few different street driven vehicles. I was big on the KM2s until I tried MTRKs. I had KM2s on my TJ, as well as my Toyota Xtra Cab and they both works really well and I was very happy with both sets. When I had my SAS'd 96 4runner, I decided to go with the MTRKs and I was much happier with those versus the KM2s. That could have been due to different vehicle weight ratings, but I wouldn't hesitate to run either of those tires on another street legal vehicle.
Another couple options as well could be the Blue label or DOT Krawlers, or the DOT trepadors if you want something a bit meatier as well. Several of my friends have run both of street driven vehicles with no complaints. They work really well offroad as well.
