Strange , I have a set of km'2s on my 06 duramax , (325/60-20)= 35.6 tall 13.2 wide , and I am very happy with them. The only thing that I can say bad about them is they are not a good snow tire on plowed roads , (they do ok in the deep stuff) and as they wear they are getting a little loud , (they have 37,000 miles on them now , 1/4 tread left) , but other than that they have been a nice tire all around , but I dont like the price either , 568.00 each. My buddy has 35" nitto muds on his 07 dodge diesel and he like's them as well , but he tells me that they dont do well on plowed roads either , (no mud tire really does) and they are for sure louder on the hwy. than the km'2s and heavier as well , but he likes them all around as well , and they look mean. I guess all tires have there down sides , but I am very happy with my km'2s. IMO. I dont think any radial tire compare's to the old bais tire's , (monster mudder's , ground hawg's , swamper's) in the mud. I agree with bucket , I have no problem with bais tires anywhere , I run them on a lot of my square's and they perform great in most case'es and once they heat up they round out and ride pretty good.
