Introduction Size Award
Zigzag center rib design increases grip performance on straight way.
 
Four broad circumferential groove design with 35% void ratio enhances drainage efficiency and maneuverability on wet road condition.
 
Broad circumferential groove design (outside groove wall angle>inside groove wall angle) drains water more easily, and even prevents slipping.
 
  3-Dimension arc groove design between blocks helps increasing stiffness between blocks, and also disturbs air flow in grooves.
 
Applying “groove in groove” concept on circumferential grooves disperses stress on tire surface, and prevents irregular wear and noise produced by the friction between air flow and groove wall.
 
Separating circumferential grooves and radial grooves decreases rolling noise.
 

Adding sipes and thin grooves on blocks and shoulders balances block stiffness and riding comfort.
