I drove for about 15 feet in the snow on the stock tires (on my driveway), and I almost wasn't able to make it into my garage. My driveway has a very very slight incline, and I almost had to get my wife to push me to get into the garage. The stock tires are SCARY in the cold and snow IMO.I've still been driving around on the stock tires here in Mich. It snowed last night and this morning I didn't have any issues. Then again I have never bought a pair of snow tires, so maybe I'm just used to the lack of grip?
