I'll be picking up my 2013 GT in a couple of weeks. This will be the 4th stang I've owned over the years. On past cars I've always had a set of dedicated set of summer wheels and winter wheels with Blizzaks (or similar). The midwest winters can be pretty harsh. My question is since the OEM tires are rated as all-season, will they be acceptable in the snow? Has anyone used these tires through a snowy winter?
