17 x 7.5" Sport Edition wheels and 215/45R/17 General Altimax Arctic snows.
Same diameter as the stock 235/40R/17s (25.4 in) so they shouldn't throw the speedo reading off.
I got the rims for about $95/ea through a local tire dealer, who ordered them through the Tire Rack, got the General snows at a very reasonable price from the same source.
BTW: That's a front hub/wheel in the photo.
