The ContiEcoContact EP (Economy Plus) is Continental's Passenger Summer tire developed for the drivers of the Smart Fortwo (Original Equipment on 2004-2006 model year vehicles). The ContiEcoContact EP's low rolling resistance design helps save fuel and reduce vehicle CO2 emissions while providing traction in dry and wet road conditions. However like all summer tires, the ContiEcoContact EP is not intended to be driven in near-freezing temperatures, through snow or on ice.ContiEcoContact EP tires feature a silica-enhanced compound into an asymmetric design with solid tread blocks and a continuous rib on the outboard shoulder to promote responsiveness and cornering stability, while a continuous center rib provides constant rubber-to-road contact to reduce noise and control the longitudinal forces experienced when braking. Circumferential tread grooves and independent tread blocks on the inboard tread resist hydroplaning and enhance wet weather traction. The tire's internal structure includes twin steel belts to stabilize the tread area on top of a polyester casing that promotes consistent ride quality.Note: The ContiEcoContact EP Passenger Summer defaults to the Passenger All-Season tire category because there aren't enough Passenger Summer tire models to support a performance category.*Specific sizes featuring Economy Plus technology are identified as such on the Sizes tab, as well as on the tire's Specs tab.
