About this tyre
Rock 818
Zigzag grooves
Zigzag groove design. Zigzag and trailed main grooves enhance the strong traction; improve the drainage and anti-skip performance. Large slope tread grooves design provides excellent stone removing performance.
3D steel sheets
3D interlaced steel sheets design. 3D interlaced steel sheets increase the grip ability, braking force and safety of driving.
Closed shoulder
Coherent closed shoulder design. Enhanced rid and coherent closed block design on shoulder prevents the leaning-grind caused by heavy rigidity, and remain the high-speed turning agility at the same time.
Irregular pattern
Irregular pattern and multi-pitch design brings silence and comfortable ride.
