I did some research on my tires, because I am concerned also about snow driving. This is my daily driver. I have the Continentals and I went to the Conti web site. They have a good explanation about winter driving using a low-profile, wide tire. It makes sense. Considering that the tire IS wide it acts like a plow and pushes the snow, since it can't push it out to the sides enough it eventually starts to ride UP on the snow and then tire-to-road contact is lost and we lose traction. A narrow tire doesn't have this problem because it plows less snow and can stay in contact with the road.

So... that being said, to really get optimum traction for our XF's we need narrow tires, and I think that would look really lame.

The wife has a Chrysler 300, we use it in deep snow. And so far we haven't had too much of the white stuff around here in south Chicagoland.
