Multi-wave sipes are thin, modified slits manufactured in the shoulder block of a tire. As the tire wears the two walls of a multi-wave sipe interlock, decreasing block movement and keeping more of the tire tread in contact with the road surface. The results are improved wet and dry performance as well as reduced irregular wear and noise, which can be caused by irregular wear.

Multi-wave sipes help to keep more of the tire tread in contact with the road surface. The benefits are improved wet and dry performance plus reduced irregular wear and noise.
Our innovative Silent Wall technology utilizes perpendicular serrations on either one or both walls of a groove to reduce pipe resonance, resulting in a quieter ride.
Conventional Groove Wall
|When silent wall technology is applied to the groove wall, air flow is disturbed by dense perpendicular serrations. The result is reduced noise and a quieter ride.||In a conventional groove wall, air flows through the groove without being disturbed. This creates a whistling sound known as “pipe resonance”.|
