1. Silent grooves on main ribs
Same grooves void ratio at any tire cross section for smooth air flow to effectively reduce pattern noise. It connects the central grooves sa silencer.
2. Special shoulder block design
The special design with sipes at the shulder block effectively reduces the shoulder heat generaion and resnance during tire rolling.
3. Silent pitch arrangement
Silent driving experience is achieved by optimized pitch width adn arrangement, pitch displacement design to reduce tire harmonic noise.
4. 4 wide longitude grooves
4 wide longitudinal grooves to enhance water evacuation on wet roads, prevent sid slips and improve traction by well-designed angle.
5. Tilted sipes on center rib
Center rib ensures straight line stability and improves acceleation.
6. Anti-uneven-water shoulder strip
2 anti-uneven-water strips at the shoulder in order to stabilize tire profile and ensure suficient shoulder support and stability at high speed cornering.
