The Pilot Sport 4S ZP is Michelin’s Max Performance Summer run-flat tire developed in conjunction with some of the most demanding vehicle manufacturers. It was designed for serious drivers looking to maximize the performance potential of their sports cars, performance sedans and powerful luxury vehicles plus provide temporary continued mobility after a puncture has allowed complete loss of pressure. The Pilot Sport 4S ZP excels in warm, dry and wet conditions, and like all Max Performance Summer tires, it is not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice.
The asymmetric tread pattern of the Pilot Sport 4S ZP features side-by-side, 24 Hours of Le Mans-derived compounds. The low-void outer shoulder utilizes a new dry-focused hybrid tread rubber for improved dry handling and braking over the previous generation tire, while the center ribs and inboard shoulder feature a silica-infused wet compound designed to increase wet braking performance. The computer-modeled Variable Contact Patch 3.0 optimizes pressure distribution across the contact patch through turns, reducing hot spots and improving tire life during aggressive use.
Internal construction of the Pilot Sport 4S ZP features twin steel belts reinforced by a spirally wound hybrid reinforcement ply. This hybrid aramid and nylon belt offers a lightweight, high-strength reinforcement above the steel belts to enhance high-speed handling, wear and durability. Specifically tuning the application of the cord filament provides Michelin engineers the ability to balance tension and strength, and a single-ply, polyester cord casing balances trade-offs between ride quality and responsive handling.
Note: Tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels, or using them to support, roll or drive a vehicle.
Flexing of the specialized rubber compounds used in Max Performance Summer tires during cold-weather use can result in irreversible compound cracking. While compound cracking is not a warrantable condition because it occurs as the result of improper use or storage, tires exhibiting compound cracking must be replaced.
