We got to experience the Jeep G.C. in the snow recently and find that the 265 60 18 just don't cut it. Having a large foot print effectively acts like a snowshoe causing the vehicle to float on top of snow rather than cut through it. We've decided to to get a dedicated set of rims/rubber in a smaller size keeping within overall diameter. The Laredo base came with 245 70 17 as the standard wheel vs our 18". Although the snow does not stick around here long, ice becomes more of an issue and so will look for a tire with good ice grip as opposed to a M+S tire. Dropping the width down should increase snow carving also. There goes more money, but well spent IMO if it prevents one accident and increases her driving confidence.
I'm leaning towards the Bridgestone Blizzak DM-V1 as opposed to the Michelin X-Ice Xi2. Word is the Michelin are great the first year and last but the rubber hardens up and becomes less effective vs the Blizzaks.
