Look, most of these guys have a pretty good idea of how to drive in the snow. I'd listen to them if I were you.
As far as 6 inches of snow, what do you plan to do, practically plow your way through it? Really, it's a car not a pick-up truck.
Want a little better traction? Get your tires siped.
tires siped? this car is my DD, and i have put a ton of money into it lately. im just trying to do anything extra i can to protect my vehicle. sh1t happens in the snow, even to good drivers. its not like im a madman in the snow, just figured more traction wouldnt hurt
