This is my second winter on these tires, I have used winter tires on my cars for years now, even though we haven't been getting as much snow around here as we used to growing up. I love that with these tires I can actually drive my Carrera in the snow, rather than keep it parked like a garage queen. Since most folks in my area don't switch to snow tires, they are utterly baffled when they see me driving with ease in several inches of snow. Braking performance in snowy conditions is fantastic.
General cold weather driving, sans snow, is very good. The tires maintain their grip on dry roads, slide progressively and aren't as squirmy in the tread as some winters are. The downside is a bit of tire noise, especially under braking, but it's not too bad. Hydroplane resistance is very good, even in heavy rain.
Keep your performance car on the road even ion winter weather! Highly recommend.
