The KMs are crap mainly due to inferior braking, but not sure about KM2s. The MTRs are much better in 2WD and 4WD. However, a DuraTrac (or Hankook RF10 or that newish Toyo AT) will be a great option unless you can use a true winter tire which will do far better in the city/highways. Offroad on fresh snow, I would prefer something like the MTR or DuraTrac. I have 35" MTRs now, and just used those in some majorsnow. They do pretty well for a MT, though my Hankook Dynapro RF10s on the 4Runner do even better in the city. Basically, a softer rubber compound and more sipes will do better when cold/snowy.
