Pathfinder I
Wet traction is really the only downfall for the KO2. There are so many threads on this tire on so many forums and you'll find that the recurring grip is wet traction. There are people who claim they don't have any problems but you'll rarely find anyone boasting the KO2 prowess in wet. There are also a lot of fanboys out there...I’m looking for tires for my LX470 and was advised against getting them by the tire shop because of them being slick on wet roads. Is it that noticeable?
If you want great wet/dry/snow traction from an aggressive AT then look at the Wildpeak A/T3W. For a mild AT the Continental TerrainContact and Yokohama Geolandar AT G015 are excellent in wet but the Conti isn't great in snow. I read the Ridge Grappler also has great wet traction as well but I've never run that tire. I've run the others.
