Should be great. Just make sure you're OK with the 18' look. 18' 19' 20' - all are OK as long as they're dedicated snow tires. In the worst of worst conditions, 18' may provide more traction than 20' but my real life experience with 20' Pirelli Scorpions this winter (including the New England blizzard a few weeks back) was outstanding. I REALLY had to try to get even the mildest slippage (in a parking lot, of course).
