Yesterday I had the opportunity to drive the new 15 on wet snow--only around an inch--car did great on take offs, braking, and traction whilst traveling. However, I couldn't believe it I was traveling down a slight hill and started sliding like the wheels were on a bed of ball bearing off the side of the road. Fortunately, I got it to respond as it hit the soft shoulder and turned it back on the asphalt. Checked out the tracks today and I wasn't far from a power pole before I corrected. The stock tires--all season-- were crap
under those conditions. I can't recommend strongly enough that if you are going to be driving in snow get snow tires.
