I don't drive my ZL1 in snow or ice, only cold, dry sunny winter days in the midwest which can be few an far between. I do just fine on my Conti DWS06 on a separate MRR wheelset. I personally disagree that the performance gap between a good all season and winter tire in the dry is much at all, and I think tire companies do a good job of suppressing related performance data on cold, dry pavement. The little data I have found favors a winter tire's stopping distance by only a few feet. Like someone else mentioned, getting great traction on anything other than a summer performance tire in a high hp car is laughable, so I don't worry and just enjoy the occasional winter joyride. I do a square setup with all season so I can use them for burners if I please before switching back to summer rubber. I agree winter/snow tires are better on ice and snow than most A/S patterns, but I don't drive on ice or snow.

Somebody show me cold weather performance data on a dry surface.
