The AVID TOURING-S is Yokohama's Standard Touring All-Season tire developed for the drivers of coupes, sedans and minivans. It was designed to combine ride quality, smooth handling, durability and traction in any season, including in light snow. The AVID TOURING-S uses Yokohama's Tri-plex Tread Compound to provide long tread life and all-season traction. This compound is molded into a symmetric tread design that features Silent Shoulder variable tread block sizes and a central Twin Rail Stability Rib to reduce tread pattern noise while offering confident maneuverability. The intermediate tread blocks feature Tapered Rain Channels working in tandem with circumferential grooves to help evacuate water and enhance wet traction while Cross Traction sipes provide biting edges to increase traction in wintry conditions. The tire's internal structure includes twin steel belts reinforced by nylon belt edge strips on top of polyester body plies that are stabilized by tall, tapered rubber sidewall inserts for better absorption of bumps and road vibrations.
