The Crossfire has a unique offset, so your old rims aren't going to work. My advice is to go to tirerack and check out the cheap new rims they offer, there are closeouts all the time and who knows, maybe you'll like them over the stockers and then you could use them for snow tires. Speaking of those snow tires, as big of fan I am of the Michelin "Pilot" snow tires, I'd get something that has more emphasis on grip and now so much on speed ratings because this car must SUCK in the snow, so forget about speed rating and handling for the snow tires.
