The Pirelli P Zero PZ4 tires are developed for some of the most exclusive and highest performing vehicles available.

Sports car tires focus on dry handling, grip and lateral stability, while the luxury vehicle tire is tuned for comfort and noise. All of the P Zero PZ4 have wide grooves for efficient water evacuation and hydroplaning resistance.
