Go to the Tire Rack site (www.tirerack.com) and plug in winter tires for the Crossfire. They will give you the correct tire size. However, I tried buying a combo package for winter, using 18's all around, and they do not have wheels. Go figure.

I am looking at keeping the 19's on the rear, and going with Dunlop Winter Sport 3D tires in 225/40VR18 (Front - $169. ea.) and 255/35VR19 (Rear - $234. ea.). I am moving back to South Dakota, and will most likely need them this winter.

Good luck.
