Go to your dealer and get the pamphlet for the Porsche approved tires. Once you see which tires are approved for your car then you can rush to Tire Track. Suggestion is to have your dealer install them for you. I went through an experience with the tires that made me realize of my stupidity in order to save time. Porsche has the right equipment to balance your tires, the right lead weights etc. Their engineers pick these tires for optimal performance for the car.
