I picked up an extra set of stock 18" rims from Bee Venom a while ago so that I can put snows on the four crappiest (best are 3 of Mr. Venom's and 1 of my originals).

Snow tire I am looking at is the FIrestone Winter Force 225x60R18 (Tire Rack$92 plus shipping). May be a bit small for a lifted rig, but not all that expensive.
