Description

The Michelin Pilot Sport All Season 4 is an all-season tire focused on precise control and quick reactions. Dynamic Response Technology helps transmit steering inputs to the road accurately.

Michelin pairs a Formula-E tread pattern with silica and a new generation of functional elastomers, giving strong grip and confident braking on wet and dry roads. Rolling resistance is also lower than on its predecessor, so more power reaches the pavement.

This 255/40ZR21 size carries a 102Y load and speed rating with extra load (XL) construction. It has 10/32-inch tread depth, a 50 psi maximum inflation pressure, a UTQG rating of 540AAA and an overall diameter of about 29 inches.
