- Center sub grooves with shallower depth enhance vertical/lateral block stiffness to avert block deformation and further reduce energy consumption. <br />
- Shoulder groove bottom with big angle design retain shoulder block continuity, weaken block wriggling, and reduce energy consumption. <br />
- Four circumferential groove design enhances drainage performance and safety for wet road driving. <br />
- Center rib design reinforces straight driving and handling performance. </p>
   
<p>Circumferential rib design on tread shoulder, with thin sipes instead of run-through lateral grooves, prevents groove resonance and reduce noise generated by run-through lateral grooves.<br />
Adopting excellent dispersible silica and unique crosslinking agents reduces rolling 
resistance substantially as well as enhances wet grip.<br />
Using unique synthetical rubber with “Chain-End Modification” strengthens fuel saving and traction.
