Owned a set of KO2s (35x12.5x18) on my old JKU, outside of being too wide for the jeep I thought they were good overall, not necessarily standout at anything. They did not fair great in real intense rain or snow/ice in my perspective.
Hated the Toyo RT (35x12.5x20) on an old GMC 1500. Absolutely terrible in the rain/snow and didn't make up for it in the dirt or mud. Loud as hell and wore faster than I liked for their performance.
Falken AT3Ws (37x12.5x17) on my dodge 2500. Absolutely amazing tire. Quiet for most of their life, great snow and ice performance, great in the rain, absolutely horrific in any wet off-road conditions. I don't understand how they can handle so well on wet pavement, and yet I almost got stuck on my own lawn in the rain, and caked up so much dirt/mud off road at times. Still, overall they are such a great mix of capabilities it's really hard to dislike them.
Falken RT (38x13.5x17) on my dodge 2500. Truck became more dedicated as daily and off-road rig. They are worse in the snow than the AT3W but not by a huge amount, just notable. They are vastly superior in the dirt and mud though. I can easily crawl through trails, rocks, etc. that the AT3W struggled with.
I was very interested in getting the AT4W but decided to go the RT route for now, and gotta say I'm glad I did. I am also very interested in the KO3 but until they come out with at least a 37, I'm holding off.
Eventually, I'll likely run a set of winter tires (AT4W or perhaps the KO3 if it becomes available) and then jump to a proper MT for the late spring through fall.
I know some guys were talking about the Kendras. I've heard good reviews on them but what makes them great is also their weakness, soft sidewall.
