I have toyos myself and they have been good to me. Tread life is way better than nittos. I wanted the KM2 but I need em in a 22" rim size and about 37-40 size but the biggest they have is a 36.5.
Havent heard anything bad about the KM2 either. My buddy has a set on his Dodge Power wagon and he says they are not to bad and pretty quite.
