We had snow and ice here for the past week , and my new 11 GT was no problem with the P zero nero aw 's . I certainly wasn't pushing it though

 

I got new tires about 2 weeks ago and they are a huge improvement of course. Eagle GTs. Seriously so much better.

 

Maybe we need to define "ice"..I have the '11 GT and I installed dedicated winter tires on them (Michelin X-Ice xi2), when there is some snow (maybe 1-2 inches) on the ground, no problems, when the snow layer freezes to hard pack/ice, no problem...yesterday we had freezing rain, so more of glare/wet ice uniform layer on the street, car would not even steer once I was off the driveway! and thats with hardcore winter tires...I dont know if my experience is typical, but cannot imagine the car doing better with the stock all seasons..
