Chains work well to provide traction through deep snow where it is not packed down, or where you have new snow sitting on a layer of ice or very hard packed snow. Up here in igloo-land we only see them used on country roads or in the mountains during heavy snow fall.

Notice I said TRACTION on DEEP SNOW. Steering and braking are another question. What tires are you running on?? Remember the poor soul who drove his car into a tree last week in his driveway??

If you do not have a full set of full winter tires (none of that "all season" Bull$hit) and are not experienced in winter driving, then chains can lull you into an incredibly dangerous situation - rather like a 4WD SUV driver who does not understand the difference between traction and tire adhesion to snow on braking or steering.

Please consider staying home unless you are going to buy a decent set of full winter tires (Nokian Hakka 1's or 2's, Bizzaks, etc.) or at least a full set of Nokian WR's (the only all season tire with decent snow and ice performance). My beloved 300SD on Michelin Harmony's (so called quality tires) is a dangerous POS on snow and ice because of the tires - the rubber compound is way too hard for cold weather use. I am buying a set of Nokians on Monday.
