About this item
Product details
Before purchasing tires, make sure to use our Tire Finder to select the right fit for your vehicle.
Improved Dry Handling Performance
The revolutionary Multi-Compound Construction delivers unmatched levels of dry and wet grip exactly where you need it to perform at a top level.
Optimized Preassure Distribution and Longer Tread Life
The Pilot Sport 4 S has Variable Contact Patch 3.0 which improves the tire life during aggressive driving by optimizing pressure distribution across the patch. This reduces hot spots through turns allowing the tire to last longer and still perform at a maximum level. Michelin Total Performance overcomes the usual tradeoff of wear for grip to deliver both incredible traction and improved tread life
Maximum Combined Performance
The Maximum Combined Performance. 1st in dry lap time. 1st in dry braking. 1st in wet lap time. 1st in wet braking. Fall in love with your car’s untapped potential with the best max performance tire, the Michelin Pilot Sport 4 S. Our Dynamic Response Technology continuously adapts to the road for ultra-precise steering, outstanding cornering power and remarkably good treadlife for a summer tire
Premium Design and Rim Protector
The Michelin Pilot Sport 4 S has a premium touch finish that provides a dark velvet effect on the external sidewall, while a deep rim protector guards against light wheel damage.
MICHELIN® Acoustic Technology effectively reduces vibrations caused by the road resulting in a significant reduction of interior noise by approximately 20%*.
