The ADVAN Sport A/S is Yokohama's Ultra High Performance All-Season tire developed for sports car, sporty coupe and luxury sedan drivers looking for year-round performance. Designed to offer smoother ride comfort for a more enjoyable drive, the ADVAN Sport A/S provides traction in dry, wet and wintry conditions, even light snow.Featuring advanced polymers that keep the tread pliable in cold temperatures while extra silica provides superior wet and winter grip, Yokohama's advanced tread compound combines all-season handling with good wear. The compound is molded into an asymmetric tread pattern to blend 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. Circumferential grooves help evacuate water from under the tread to enhance wet grip. Streaming Z-Grooves create large biting edges to enhance 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.
