The Classe Premiere CP671 is Nexen's Grand Touring All-Season tire developed for sedans, coupes and compacts. Designed for all seasons, Classe Premiere CP671 tires combine a quiet, comfortable ride with all-season traction in dry, wet and wintry conditions, even in light snow. The all-season tread compound of the Classe Premiere CP671 is molded into a symmetric block design with broad shoulder blocks and a continuous center rib to promote cornering and directional stability. Four straight wide grooves channel away water to avoid hydroplaning and maximize traction on wet roads while lateral grooves and multiple sipes enhance starting and stopping capability in foul weather. The tire's internal structure includes twin steel belts reinforced by spirally wrapped nylon on top of a polyester casing to combine strength and durability with ride comfort.
