Anybody using all season tires? Recommendations?

Here in my area, the earliest snow flurries can come as early as the first week in October. Last year, the last snow that stuck came as late as Memorial Day weekend. That was unusual, but we do get snow that sticks until mid April normally.

Which means that, unless you want a Stingray to be a strictly 6 month a year drive, some all season or snow tires are advisable, on a second set of wheels. For a pure winter tire, I see that a Michelin Alpin PA4 is available in z51 sizes, but going out and intentionally driving the Stingray in mid winter snow would seem crazy.

I am looking for an all season tire to fit on a second set of wheels that would get me past the "not recommended below freezing temperatures" limitation of the stock Michelins that come with the car, and allow me to get around on clear cold weather days, and get home if an inch or two of snow were to suddenly come out of nowhere. I am leaning toward the Continental ExtremeContact DWS, an "Ultra High Performance" all season tire which comes in Z51 sizes, seem reasonably priced at Tirerack, and of all the all season tires, have a higher than average snow traction rating. They are UTQG rated 540 A A .

Anyone have any experience with all season tires, especially in light snow, and how they perform in dry roads? I would refit the summer tires to the car in warm weather months. But wouldn't it be nice to take a mid winter break, drive the Stingray to a warm weather location in mid winter for a couple of weeks, and be able to drive home again and make it up a recently plowed hill?
