I picked up a separate set of rims and tires from Tire Rack. I went with some clearance rims, and a reasonably priced snow tire.
The size and type was the 235/60R17 Goodyear Ultra Grip Ice WRT.
This is the first set of winter/snow tires I have had but the difference is amazing. Another bonus is that when these are shot, the new tires are around $115 apiece.
Plus I can stick to a decent 20" Summer tire for a reasonable price and not have to go with an All Season.
The whole setup shipped was about $1200.
