Asymmetric pattern design with four circumferential grooves emphasize drainage performance on inside tread for getting better wet performance. Lateral groove design on center rib optimizes block stiffness and enhances comfort. Interlaced lateral grooves on outside intermediate tread block can preserve block stiffness and enhance handling performanc... moree. Narrow lateral groove design and the application of 80 pitch arrangement can reduce pattern noise effectively. The noise prevention bar on the bottom of lateral grooves can disturb air flow and reduce noise generation from lateral grooves. The oblique chamfering angle design applied on lateral grooves on tread shoulder can prevent irregular wear on the premise of keeping tread stiffness. Flat tread profile design can even tire contact pressure and further improve irregular wear.
