Having smaller tires doesn't particularly help with snow traction, but narrower is in general better, but the main reason for going smaller is 1: Cost (smaller is cheaper) and 2: Potholes. If you live anywhere that has roads, chances are winter is pothole season. The more meat you have on the tire the better chances you have of surviving a trip to the bent rim repair shop.
Given how bad the roads are in NY even starting around this time of the year, I can't see any reason for having or wanting a big rim for the winter, esp going up to a 20"
