Studdable tires on the fit? Yes you can run them as they are just regular snow tires with the pre-drilled holes for studs if desired. My General Altimax Arctic Tires are studdable and the Hankook & Winterforce tires I've used in the past (on other cars) have all been studdable. In NC, you definitely don't need to have the Studs installed and I've never used them here in VT. Those would probably be more than competent in your area. Here I use 185/65/15 on alloys from an integra to raise the car up a tiny bit but with a 2012, you'll want to use the factory wheels to maintain TPMS.
Any particular reason you are looking at snow tires? The stock all seasons should be plenty for your needs in NC.
