whats everyones general opinion on the km2's?
Had them in 35s on my last Jeep for about 40k miles. They are great mud and rock tires for the first 25k miles. After that, they get ridiculously loud and very slick on wet surfaces. The lugs are very large and the siping is very shallow. Therefore, you need to rotate them religiously every 3k miles and after 25k miles or so, all the siping is gone. I should have replaced them after 25k miles, but figured I'd use them until they got damaged.
I didn't like them at all (even when they were new) for snowy or icy roads. They just didn't have enough siping to grab on. Now, in deep snow off-road, they were awesome - very similar handling to mud. But on the road, I preferred driving my wife's Jeep with 35" BFG A/Ts.
I think the BFG M/T KM2 is the nicest looking mud tire out there. The lugs are large and clean. The profile is classic and the tread pattern is just awesome. I really love the look of them, but they just don't last as long as I'd like them to.
