Just curious as to what brand tire is on the GT coupe with the 17inch rims? The Malibu Maxx that I drive right now has some crappy Bridgestone tires which are supposed to be snow and mud rated, yet when its really cold out or a little icy I can't keep the MAXX on the road. Spun close to 200 degress around the other night going 30mph in some snow. Any one have problems like this with their G6?
