I have never had any luck with the K02's well to be fair the old AT's. I have had lots of luck with the km2's to be fair the MT's. I always only ran the MT's street or offroad. Got decent miles out of them. I can never get through a set of the k02 AT's they cup and bubble or dont wear tread evenly even on the rear. I replace them and have gotten at least twice the life plus they self clean better.
It is weird to me to read all of the reviews here that are good, but I am talking different vehicles and same results. I just never had any luck with them. I hate to talk bad because obviously they do better for other people.
I think my next set of tires, I am going to test the Toyo MT's They looked pretty agressive and cool. but I am testing the duratracs now, and I have to say they are pretty awesome so far. I will write a review if that status changes.
