I've gone through many sets of snow tires ice racing, and I've tried alot of them.

General Altimax Arctic - Best value for the money, deep siping and soft rubber makes them grip like more expensive tires, Nokian knockoff tread design clears slush extremely well. Took me to 2 club championships last year, but soft rubber means they dont last long.

Anything from Nokian Tire - Excellent tread designs, lots of copycats on the market. They don't give up much grip as they wear either. Expensive, but worth the money for a daily driver.

GT Radial Champiro Ice Pro - An Indonesian Nokian knockoff tread design, the rubber compound is a bit on the hard side for a true snow tire. Not terribly bad for a tire from a country where it doesn't snow.

Continental Extreme WinterContact - Heaviest siped tire I've ever seen on the market, great on glare ice and packed snow, but with tightly spaced tread blocks they struggle in deep snow.

Firestone Winterforce - Great in deep snow thanks to the open tread design, but a hard rubber compound leaves it struggling on ice.
