Here are mine and the mud they went through. These were an option when ordering my 3500at4. I have had every version of this tire on 1/4, 1/2, 3/4, and now 1 tons. Never had a problem and got great performance and life out of them. Running these at 60 front, 80 rear and they are smooth. It's been a wet month and have a section of about 4 acres that we ride the toys on. Had to test them out. Got stuck (expected as this pig is heavy) but 4wd and these tires got me through. I feathered it and they did well. By the time I reached the front road, they were cleaned out, which I love. My wife always bitches about the mud I pull from out back to the driveway with my 1/2 ton running Nitto Ridge Grapplers. Love those tires too, but so far I'm happy with the KO3s.
Great write up, thanks for the review!
