The SP10 is Dunlop's Passenger All-Season tYre developed to match the Original Equipment (O.E.) needs of first generation (2001-2003) Toyota Prius hybrids, as well as for the drivers of other small cars using the P175/65R14 84S size looking to reduce their vehicle's fuel consumption and carbon dioxide emissions while retaining all-season traction. The SP10 is designed to accommodate dry, wet and wintry conditions, including occasional light snow.

The SP10 combines traditional energy efficient tire technologies (low rolling resistance tread compound, narrow tread width and optimized internal construction) to maximize vehicle efficiency and driving range.
