The Nankang CW-30 is a tyre specifically designed for commercial vehicles, offering robustness and longevity across various types of roads. Its main groove, featuring a conical recess design on the sides and a chamfer on the walls of the lateral grooves, allows the tread to conform more closely to road irregularities, thereby reducing uneven wear. The siped pattern on the central rib equalises rigidity and improves wet-surface performance. The widened shoulder blocks increase the contact area, enhancing durability and shoulder resistance. Shallow lateral grooves combined with shoulder sipes optimise block rigidity and wear resistance in this critical area. Finally, the increased tread width enlarges the contact patch, strengthens the sidewall resistance and contributes to greater mileage.
