Michelin Pilot Sport 4S. FEATURES AND BENEFITS: Summer traction Hydroplaning resistance Longer lasting tread life High speed durability Excellent steering responsiveness Vibration free drive. OVERVIEW: The Michelin Pilot Sport 4S is a high performance, summer tire manufactured for passenger vehicles and SUVs.The tire was designed with a special asymmetrical dual zone tread design. The tires outer shoulder is manufactured from a hybrid tire compound that increases the dry weather performing capability and road gripping ability. The models center tread area and inner shoulder are made from a silica-based tire compound that promotes wet weather traction. The wet zone also features the wider circumferential tread grooves that channel water away from the tire footprint. In this manner the tire avoids hydroplaning and offers a safer summer weather driving experience. While the tire provides remarkable summer weather traction, it is not suited for winter weather driving as the tire compound loses its road gripping ability in colder temperatures.A longer lasting tread life is guaranteed. The tread design prevents irregular tread wear patterns from forming across the tread area. This is achieved with the Variable Contact Patch 3.0 that evenly spreads out the driving pressure across the tread. The equal distribution of the forces of acceleration, cornering and braking improves the tread wear length and increases the tires usability. In this manner, the tire is more cost efficient.The special internal structure features twin steel belts reinforced with a spirally wrapped nylon cord that improves the high speed durability. The reinforcement prevents the tire from deforming under the driving pressure affecting it as it maintains its optimal tire shape. As the tire does not deform, it is capable of performing to its highest capability safely. The reinforced structure also balances the tires tension and strength. The internal strength and tension ensure constant road contact which upgrades the steering responsiveness and accuracy. The tire is quick and precise in its response to the drivers commands and allows them to confidently control the tire in all summer conditions, even at high speeds.The Pilot Sport 4S offers a comfortable drive. The single-ply polyester cord casing lowers the road vibrations felt in the vehicles cabin by maintaining constant contact between the tire and the road. The tire closely follows the road surface, which reduces the road vibrations felt by the passengers, making the driving experience more enjoyable.
