If you are going to be driving mainly on sealed roads with the occasional offroad, the Bridgestone A/T "dueler" is more than adequate. In fact for higher cruising speeds and wet weather, it's probably better than the KO2. I travelled to Cape York and other off road places with them and they were trouble free. On concrete and bitumen sealed roads their noise was similar to highway tyres.... The Bridgestones did give a noticeably harder ride however when they had worn down close to minimum legal tread depth (a bit over 3mm or 1/8" ) after 70 thousand km. I expect this is the same with most A/T tyres. If I were not so "determined"
to visit a couple of out of the way places later this year (
) where the KO2s will probably earn their keep, I would have opted for the Bridgestone setup.
