I thought those of you who live in cold climates may be interested in this page that reviewed 10 winter tires. I got an awesome deal on some Hankook icept w616 winter tires a few years back from discount tire. They were a new design at the time, so had no reviews or tests. I've never owned winter tires before, so am not sure if they are good or bad (they are a HUGE improvement over the stock all seasons though, not surprisingly). Periodically I search for reviews to see how they rate, and this is pretty much the first test that came up.

Short version: ranked low in wet and dry situations, and quite good in snow and on ice. However, they surprisingly ranked #1 in fuel economy!
So for you other fuel mileage nuts, this might be a good tire to consider if you need winter tires. I've been happy with them. They help a lot in the winter, and after 3 seasons (maybe 15-18 thousand miles) they aren't showing much wear at all. I would absolutely buy another set of these. They tend to be $60-80 on discount tire, and Hankook often has rebates too.
