I wouldn't sipe the tires either. We drive in all kinds of conditions up here in Alaska. I would say most people up here buy 2 sets of tires( pair of Blizzaks for winter, softer tire for traction and a set of summer tires). Me personally, I buy a set of good all terrain tires and have done well. First year I've tried the Goodyear Duratracs, usually used either BF All terrains or Toyo AT's. I don't have a diesel truck, got a gas truck cause it just warms up so much faster in our cold *** winters!!!!
I've only been to Alaska (anchorage) once in the winter and man you are not joking it's cold up there! I think you could almost run blizzaks all year long! But I've also been up to Anchorage a few times in the summer, and once to Barrow and that whole state is just beautiful.
