The void ratio of the inside and outside are respectively 38% and 34%, which improve drainage efficiency and wet handling.
With broadened circumferential groove width, the section area of inside/outside grooves are increased 21.3% and 43.8% respectively compared to the conventional design. The grooves allow more water containing for better drainage performance.
Brand new profile design and reinforced sidewall design upgrade tire stiffness.
Serrated wall of circumferential grooves discharges water effectively and reduces the noise caused by the friction between airflow and groove wall.
The chamfering angles of lateral grooves reduce rolling sound and improve block stiffness.
