I would rather have the added insurance of snow tires, your up in Fairbanks, all season tires like to turn into hockey pucks at those temps. If it were me, I would run a dedicated set of winter rims and tires. I have tried hankook rw11's and general alimax arctic, I would go with either option. And if you decide to get some, go ahead and buy all 4. All seasons are a jack of all trades and the master of none. I know its a long winded answer but its an important question.
