The stocks aren't too bad, but if you have to commute to work I would get some snow tires. If you want buy a package deal through tirerack that comes with steel wheels and tires together.

Do you have a I4 or V6, cause I got some wheels with some studded snow tires that'll fit I4's that'll be great for the winter and better looking than Steelies. I can hook you up with some new snow tires too from my friends shop.
