Our old set of trusty KO2s took one for the team, so the opportunity presents itself to go bigger and try something new... One size up for our XC60 is 255/6018 but there are only a couple All Terrain tire options, and then the choice was easy since only one of the two is TrippleMountainPeak rated for snow: The Hankook Dynapro AT2
Much searching found few if any decent reviews on the AT2, so let's roll our own and torture test these shiny new South Korean yet American Made tires over the course of thousands of miles and two trips through Death Valley.
