Goodyear Nordic (from Canadian Tire) 205/55R16
great price, excellent snow traction, very good ice traction. Accepts studs. You can get them in the stock 16" wheel size. directional V tread for excellent slush/wet traction. At highway speeds they are a little noisy

I've only used them for 2 weeks during on major snow storm-melt-refreeze. And i never got stuck. Even when the snow was deep enough that I was plowing it with my bumper (and denting all the heatshielding underneath)

edit - I have now proven that they are excellent on ice too. This winter I raced in a rally-x on a frozen lake, and I beat all of the 2wd cars (including cars with studded tires)
