Last winter I ran new 285-55-18 Pirelli Scorpion Zeros. They sucked in the snow. I'm embarrased to say that I had to be pulled out of a ditch after a wheel lockup and slide down a hill. I swore I wouldn't let that happen again. I just got Blizzak DM-Z3 265-60-18 mounted on the stock rims. No snow yet, but I will post my review after a couple days of winter weather commuting.
