Here's some 16" steel wheel info for owners (U.S.) who might be interested in sizing down to 205/55/16 tires for the winter. I found (3) sites that carry the 16" steel wheel that will fit the CT...Summit Racing, Tire Rack - Your performance experts for tires and wheels, and Home - Discount Tire Direct

Summit Racing are the least expensive ($49.95 ea.), but Discount Tire will match their price. If you should need any additional info...let me know.
