The large and deep grooves on the shoulders aim to increase the driving performance. Three main longitudinal grooves provide good directional stability and reduce irregular wear and are adapted to various conditions. Wider running surface and the puncture resistance formula reduce abrasion.

Three vertical grooves in winding provide good driving performance, which are suitable for middle and long distance. Steer or trailer wheel is recommended. Narrow grooves reinforce the drainage and prevent sideslip. Closed shoulders reduce eccentric wear and enhance driving handling. Unique design of the carcass ply and tread belt improves safety and the performance of overload.

Big angle of the grooves avoid transformation and cracking. Variable angle of groove bottom will effectively prevent stone retention and improve service life. Arc shape of the grooves makes the pattern look better and keep rigidity. The middle sipes aims to balance load and wear and to avoid groove bottom cracking.
