Michelin Pilot Sport 4S – 245/40R18

Part Number: 37666

Max Performance Summer Tire for Street and Track Use

The Michelin Pilot Sport 4S in size 245/40R18 is a max performance summer tire designed for drivers who demand high levels of grip, responsiveness, and consistency in both dry and wet conditions. It is commonly used on performance-oriented street cars and is also well suited for occasional track days and spirited driving.

Performance-Focused Design

The Pilot Sport 4S uses Michelin’s dual-compound tread technology, with a dry-focused compound on the outer shoulder and a wet-focused compound on the inner portion of the tread. This design helps balance cornering grip with wet-weather traction while maintaining predictable handling characteristics.

A rigid tread pattern and reinforced internal construction contribute to precise steering response and stability at higher speeds. The tire is engineered to maintain consistent performance across a wide range of operating temperatures typical of summer driving conditions.

Street Manners and Longevity

Despite its performance focus, the Pilot Sport 4S is designed to deliver relatively low road noise and stable ride quality for daily use. Michelin’s compound formulation is intended to provide improved tread life compared to previous-generation max performance tires when used under normal driving conditions.
