With a winter wheel setup, you'll want to go the less costly route (typically steelies). Road salt, snow, road salt, debris, ROAD SALT, etc. will do a number to your wheels so there's no need to spend any more than you have to on those wheels. Not only that, but you'll also have tires mounted once and not have to worry about seasonal tire changeover on one set of wheels. Just mount once and re-program the TPMS. We had a discussion about TPMS, too. I have to admit I'm not as well-versed on that subject, but I'm sure others will chime in.
