The Michelin Pilot Sport PS4 S Acoustic summer tire is a special modification of the same-name UHP category model for the most dynamic passenger cars. It is characterized by excellent acoustic comfort for its class. In motion, it is distinguished by exceptional precision in handling and course stability, both on dry and wet surfaces.
The high level of acoustic comfort of the tire is largely due to the layer of polyurethane foam applied to the inner side of the tread. A multitude of small air-filled cavities effectively absorb low-frequency noises and vibrations arising from the contact of the tire with numerous irregularities on the road surface. At the same time, its ride quality remains unchanged.
The tire uses the Dynamic Response technology, which largely determines the exceptional precision of handling. The essence of the solution lies in the use of an aramid-nylon cord in the breaker. As a result, its design is distinguished by low weight and very high resistance to deformation. The effect of the breaker is complemented by an optimized tread profile. It ensures the stability of the contact patch and uniform pressure on the road surface. The "icing on the cake" of technological innovations applied in this tire is the 2-component rubber compound. The outer side is made of a compound with increased elasticity, which enhances grip when maneuvering. The inner side of the tread, thanks to the use of functional elastomers, improves the efficiency of the tire on wet surfaces.
Main features:
- reduced noise level due to the polyurethane foam layer on the inner side of the tread;
- a breaker with an aramid-nylon cord and an optimized tread profile provide exceptional handling precision;
- a 2-component rubber compound improves stability when maneuvering and on wet surfaces.
