With DWS tires, the impreza could handle the 7-8 inches on snow we got in Arkansas. BUT!!!! One of the fog light cover (the black piece) could not handle it and decided to ditch the car. But holy crap the impreza was a plow. I wish I had me video camer and my in car mount. I did take some nice pictures when the snow was about 4 or so inches. But damn now I highly recommend the DWS Contenitial tires. I mean they are probably not as good as dedicated snow tires but man they really did the job. Yea they slipped alot on my girl friend's steep drive way but still got up there. But because stupid drivers and dumb SUV, I was lucky enough to test out the stop and start on a hill covered in black ice. Some how made it up the hill and pass the slower cars without slipping. Obviously, if I had punch the gas in first gear I would most likely spin my tires alot but I took it easy and the car could practically handle it all. Besides the fog light cover. That is the only thing that bothered me a little. Hearing all the snow and ice hitting underneath the car. Sounded terrible and scared my girlfriend. I wished Subaru didn't lower the car and kept it at 6.1 inches.
