Tires transform the car. It feels like it is all wheel drive. Steering with the throttle is a snap. The limits of the car on the street with these tires have not even be tickled by me; I would need a track for that. The stock Bridgestones are unacceptable and wore quickly. I thought the Hankook V-12s were good until I tried these PSS. I have a set of Pilot Alpin PA-4s on separate AMG wheels for winter use. I do not believe in all-seasons. Frankly, there is no other choice than the PSS unless you want a DOT approved race tire which has its compromises in the wet. The PSS do not.
