I have Dunlop tires and today was my first day driving in the snow with the CTS-V. I was concerned about driving in the snow having read all the e-mails about how bad the car handled with the F1 tires. Today it snowed about 3-4 inches in Central Jersey and I didn't have any problems.
The roads were pretty clean however, so I took the car on some back roads near my house just see how it handled. It is much better than the Chrysler 300 Touring I traded it in for!!
I can only assume it won't be as nice when the snow is deeper or with black ice on the roads.
Anyway this is the price we pay for a 400hp rear wheel drive car.
If you are easy on the gas it shouldn't be too bad
Good luck
