C. Precise groove arrangement

・Designed groove arrangement in millimeters. The grooves which look like one-line are actually shifted in millimeters. By shifting the timing of grounding, presents concentrating on a specirc frequency band reduces harsh noise.

Reduce harsh noise that man feel uncomfortable.

D. Center straight Rib block

・Stability at straight
・Handling

E. Non penetrating sipes Optimized the stiíness of block

・Silent
・Stability at corner

F. Single edge-cutting

・By partially applying precise edge cutting, we control the occurrence of uneven wear and suppress deterioration of silent performance. In addition, we keep block stiffness too.

Balanced High level silent performance & good handling at high level

G. Staggered arrangement of groove & sipes

・Optimized the block stiíness by placing non-penetrating grooves and sipes at precise intervals from the left side and right side of block. It improves steering stability and improves silent performance.
