DO NOT USE THOSE FOR WINTER. They are good in slush and fresh snow but next to useless on any ice/crust. The compound is also very hard once temperature goes below freezing they are like pucks.
I've had a set of All Terrain T/A's for 7 yrs and 86,000 miles on my 4x4 Element and never had an issue. Thats right 86,000 miles on one set of tires, but they wont make another winter, so next week I'm going to get a new set. I believe a large part of it is the driver, I'm in a Honda S2000 club and last winter we had a snowstorm, then 2 weeks of sunny days, so on New Years eve I planned a drive, the entire drive was dry roads and sunny, except one stretch with about 15 miles of blackice, and believe me those Extreme Summer Only High Performance tires on a rear wheel drive light car, are not snow/ice tires, but we made it, not without getting sideways a couple times.
