Or some just plain common sense. Most northern European countries have very strict rules on cars and tires in particular in the winter, and chain use as well. Your fined heavily if caught running around without winter tires or your tires are bald.
Not being a big fan of that heavy regulation, you don't necessarily need to mandate winter tires, but you could make laws that if your bald tire vehicle caused an accident, your penalized much heavier, like drunk driving, it's a choice. How you market that into something that results in less road salt use, I dunno, but, it follows that if people were driving more responsibly, less salt would be required. You certainly don't need to "pre-salt" roads before s storm.
