The Nankang CW-25 tire is a tough commercial tire for trucks and vans in pick-up and delivery service that need a strong, long lasting tire. It is also suitable for trailers. It has two central ribs with a high concentration of zig-zag sipes that offer better road contact and traction, without impacting block stability and steering response. The scalloped 4-rib design delivers optimal traction and handling while the circumferential sipes assist in stability. Pattern noise is decreased, offering a more comfortable ride. The zig-zag groove design and the solid shoulder increases durability and resistance to high scrub from frequent sharp turns in urban P+D service.
