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.

Silent Wall	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”.

Note: all technologies are not applied to all tire products. Please see individual product pages for details.
