The Yokohama AVS dB S2 was developed to provide ultra high performance for the drivers of sports cars and sporty coupes by providing year round traction, even in light snow. The Yokohama AVS dB S2's most important added feature is a revised tread pattern designed to minimize irregular wear and the resulting increase in noise.
