Talking about snow already?!? It's only May?!?
Anyway, my rule is the use of four studded Hakkapaelitta snow tires. They make you stop, turn, and go MUCH better. I was told by my local tire guy that they have a Hakka 2 coming this winter. It is supposed to be kinda of like the Hakka 1 but with more sipes and a little bit different tread pattern, but still studdable. Sweet...
