The Sumitomo ST 718 tire is designed for urban and metro fleet operations. It features a 5 rib tread design that provides superb rolling stability as well as wet and dry traction. In wet surfaces, the grooves remove water from the contact patch to enhance hydroplaning resistance and improve grip. Durable tread compound combines with the closed shoulder design to minimize wear and prolong mileage. The all-steel casing increases stability and durability.
