Allright here is the deal with winter and summer wheels. I have 2 sets of wheels the originals and my current wheels. The originals go on in the winter with snow tires, because it does snow in Michigan, and the level of control goes way up with these tires in the bad weather conditions. In addition this way I do not get my nice summer wheels all screwed up from the snow/salt/potholes and other things that come with snowy roads. I then have the summer wheels and tires that are gripier and sexier and I dont have to worry about those conditions and I get the grip and other preformance gains. I would agree with Death that your in NC and it probably barley ever snows there so you can probably use a more preformance oriented tire for most of the year and thus dont need to worry about a second set of wheels.
