I ran Ko's and KO2's for about 650,000 miles on a 1-st gen 4runner, a 4th Gen, and now a 5th gen. All had minor lifts and a bump up from stock sizes. Offroad a lot for fun and work (geologist).

The only issue I ever had with the KO2 is lack of any good wet traction on pavement. I frequently had the traction control going crazy when taking a tight turn in the wet, especially from a stop. My son got fed up with the lack of wet traction and recommended me to try the Wildpeaks AT/3.

So my initial review after about 10,000 miles with the Wildpeak vs the KO2 - no contest - so far the Wildpeak is far superior on wet roads. Dry roads - no difference so far. Offroad - no difference so far. Durability (the no.1 plus for the KO2) is out for judgement. But, My son has them on 2 3rd gens and at least 100k miles with no failures. And he's really hard on tires.

I can honestly say that I really like the AT/3 - especially in the rain. BTW - I'm running 255/80-17 (tall - skinny)

I agree with this except for the wear. I am currently running 285/70-17 SL Wildpeaks AT3W’s and they are great all around, expect the wear isn’t as good as the KO2’s I had. I will go back to the Wildpeaks again though. The wear on the E load Wildpeaks are probably much better.
