Description

The Michelin Pilot Sport 4S Autocross is an ultra-high-performance summer tire for sport and performance cars, drawing on the Pilot Sport 4S design. Dynamic Response Technology supports sharp steering and cornering, and a hybrid compound improves dry grip.

Variable Contact Patch technology spreads pressure across the footprint during aggressive driving, helping reduce hot spots and extend tire life.

This 275/35R21 size carries a 103Y load and speed rating with extra load (XL) construction. It has 9.5/32-inch tread depth, a 50 psi maximum inflation pressure, a UTQG rating of 300AAA and an overall diameter of about 28.5 inches.
