For wheels you might look at your local pic 'n' pull (or over on the Planet though shipping would probably kill the cheap part) for a Trooper or Rodeo. They have both 15 and 16 inch factory wheels. Leave 'em stock or throw a coat of flat black paint on 'em and you got some cheap, nice winter wheels. As far as size (I don't about size availability, haven't checked winter tires since I rarely have to worry about that white stuff), possibly the same diameter but in a 10.5 width. The narrow tire isn't so much for cutting through snow but it puts more weight on the contact patch area I believe (someone feel free to correct me if i am wrong).
