The ADVAN Sport A/S+ is Yokohama's Ultra High Performance All-Season tire developed for sports car, sporty coupe and luxury sedan drivers who want confident year-round capability and enhanced wet traction. Designed to provide a performance-focused driving experience plus enjoyable ride and noise comfort, the ADVAN Sport A/S+ delivers traction in dry, wet and wintry conditions, even light snow.The updated, high performance compound of the ADVAN Sport A/S+ is molded into an asymmetric tread pattern focused on blending responsive handling with all-season performance. Extra-large outboard shoulder blocks enhance dry cornering while 2-IN-1 intermediate blocks increase handling response and lateral stability. The updated compound features increased silica content and utilizes a proprietary mixing process to improve wet traction compared to the tire's predecessor. Circumferential grooves help evacuate water from under the tread to enhance hydroplaning resistance. Streaming Z-Grooves create large biting edges for enhanced snow traction while inboard serpentine grooves increase snow-shearing force for winter traction.The tire's internal structure includes twin steel belts reinforced by spirally wrapped nylon on top of a casing featuring an Optimized Sidewall Construction that extends the sidewall reinforcement higher up the sidewall to blend responsive handling and ride comfort.
