My 2008 Cayman S needs some new tires soon, I'm currently running 235/35/19 and 275/35/19 Michelin Pilot Sports. I like the tire and the ride comfort, but they are summer performance tires. I live in Westchester, NY, and we have usually 4+ month below 40 temperatures, so I was wondering if I should switch to All Season tires when replacing the current ones. I'm not planning to drive in snow, or in rain, I'm just concerned about the handling of the summer tires in frigid temperatures. I had Continental DWS on my 968, I liked them and they worked great year round. They are available in the sizes I need, does anyone have any experience with them on the Cayman on 19" wheels?
