I am a very happy new owner of a 2006 Porsche Cayman S. My first Porsche ! I have lots to learn about the proper care, but I am looking forward to keeping my car in the shape I bought it in. I would like to know what drivers experiences are with summer tires. Living in the Northeast, I want to stretch my driving season as long as I can before the snow falls. What are the reasonable expectations I should have about temperatures I can still drive in. I have lots of experience with 240Z, and 280Z, but with all season tires.
