The SP31 A/S is Dunlop's Passenger All-Season tire developed for drivers looking to match the Original Equipment (O.E.) needs of their fuel-efficient compact and sub-compact cars. Used as O.E. on Honda Civic Hybrid, Fit and Insight models, the SP31 A/S is designed to help maintain the vehicle's original fuel efficiency and environmental impact while providing all-season traction in dry, wet and wintry conditions, including in occasional light snow. The SP31 A/S combines traditional energy efficient tire technologies (efficient tread compound, a narrow width asymmetric tread design, reduced beginning tread depth and optimized internal construction) to maximize vehicle efficiency and driving range.
