Both great all terrains. Which means, good at most things, great at nothing. Ko2 is the standard for a reason, wildpeaks WERE the more affordable sexy new alternative. Were is the key, not much cheaper like they used to be. Still I got 40k out of mine before going back to ko2s on my gx470. Ko2 is a much better looking tire with a more unique tread pattern that works great in the snow and rain. Not so great in mud, but that’s why they make mud terrains.
KO2s - 50k on my 80 series and still have 8/32nds tread (roughly half way worn). Mileage warranty is 50k. Super quiet compared to other ATs I've tried.
Have the KO2 on my Ram 2500. Better traction than stock on wet pavement, no increase in tire noise and same fuel mileage. Would buy again.
I have run a decent range of all terrains. The KO2's by far performed the best; they were the most quiet, got the best mileage and performed the best offroad, especially when aired down.
Get urself some 33" BFG KO2s. You won't regret it
Currently running bf Goodrich ko2s, 245/65/17 slight rub at full lock when in reverse. (Just melted and made some space in the wheel well with no probs) loved em in the snow, mud, rain, and just daily driving
AWD with BFGoodrich KO2 tires handled amazingly.
I went with the KO2s on my 2021 Silverado 3500. The mileage difference was about 1mpg less with the KO2s. The road noise was also noticeable at lower speeds but not annoying. The performance in the rain and the little amount of snow we did have was awesome. Never had to use 4x4 in the snow.
I ran some KM3 in the Cascades for a few months before they got really slashed up on sharp rocks and punctured, then 3 years on one set of KO2 without trouble.
KO2s are overrated, overpriced and loud as well as being old technology. I've ran them and never looked back after getting TOYOs, much quieter ride, cheaper price with no offroad capability sacrifice. They also perform better in wet environments, KO2s are horrible in wet weather especially snow.
