The Michelin Pilot Sport ALL Season 4 is an all-season, ultra high performance tire for passenger cars. This one is size 295/40ZR21 XL (part number 13538). It is M+S rated.
The tread has an asymmetric pattern with more rubber on the outer shoulder for lateral grip. Full-depth, interlocking sipes and biting edges in the tread grooves improve traction in wet and snowy conditions and grab loose snow to help control acceleration and braking. Dynamic Response Technology distributes forces and temperatures evenly for longer wear life. Helio+ technology uses an advanced rubber that grips the road in freezing conditions.
