I put some of those on my 2006 Pontiac GTO. That was about 3 months ago, so I don't have a lot of ownership experience with them (yet). Initially I'm very impressed. The grip in the dry, and the wet, has been better than I had expected. Also, road noise is lower than I expected. I have no experience in the cold, or ice/snow. The tires are XL rated, so they have stiff sidewalls. That gives them a firm ride, but also great steering response. When my wife's Solstice (GXPsy) needs tires, which will be soon, I plan on getting 4 of them for it.
Hope this helps.
