Not quite apples to apples for OP, but I went from the factory KO2s to 37x13.50 Cooper STT Pros about 4k miles ago. I'm extremely satisfied with the tread wear so far. A slight uptick in road noise, but IMO I think it's to be expected regardless with the larger size I went with. Frankly, I think a 37x13.50 (not that they make that size) KO2 would be even louder. Traction has been great in all weather conditions for me. I get snow in the mountains, sand in the desert, and rain when I go back home to Dallas-Fort Worth and haven't had any issues whatsoever. I can strongly recommend this tire.
