I have being using Nokian WRA3 Winter tyres which are excellent. Chains in my opinion are an absolute pain, damage alloys and body work. The Nokians were allowing me to drive past very expensive 4x4's fitted with normal road tyres, which could not attempt the hills I was going up with ease. Nokian are a Finnish tyre company with a great reputation. Snow socks are also good if you are going through deep snow, just to get you going. Hope this helps.
