Headlining the Performance Winter / Snow category for Bridgestone is their Blizzak LM-25 RFT. It is a great tire in providing grip in both deep snow and icy conditions while also offering the abilty to complete the journey in the event of any air loss.
The Lamellen "edge effect" compound (multiple biting edges in the tread blocks to help grip snow and ice) gives you, the driver, better adhesion. This tire is not for all drivers. It was developed with only certain BMW and Mazda vehicles in mind.
After having tested the Blizzak LM-25 RFT myself, I would feel very comfortable recommending it for any of the vehicles it is intended for.
