As was already stated, true snow tires are usually softer and wear quicker. I live in Michigan and have mainly used A/T tires from most of the major manufacturers, Michelin, Goodyear, BFGs, Firestone, etc. Ironically, the best tire I’ve used for snow and wet conditions was a cheap set of Uniroyal Liberator A/T. They put most of the major brands to shame in the snow. Great traction and they shed the snow very well. They were about $110 each at Wal-Mart. They were purely a budget purchase at the time, but I went back for a second set I liked them so much. I don’t think they make them anymore, and I have since switched to a bigger tire for off road purposes. Other than those, the Goodyear Wrangler Silent Armor were also good, but almost twice the price. They are used on a lot of police package vehicles:

Now I run Federal Couragia M/T tires for off roading, which had mixed reviews, and although not for snow, they eat it up. Great traction and they also shed the snow well, but it took a little extra weight to balance them. A good tire for the price, but may not be what you need for everyday highway driving.
Good luck finding what you need : )
