The HTR A/S P03 is Sumitomo's Ultra High Performance All-Season tire developed for drivers of sports cars, sporty coupes and powerful sedans, looking to capture the performance they crave from their vehicles. Combining Sumitomo's advanced technologies, the HTR A/S P03 is designed to blend dry, wet and wintertime traction for a combination of high performance handling and stability, even in light snow.A silica-enhanced, all-season compound is molded into the HTR A/S P03's asymmetric tread pattern which is optimized to reduce profile deformation while cornering, improving handling and stability. A solid, high-tension bead apex promotes sidewall rigidity while cornering, increasing steering feel and response. The advanced "fin" design molded into the outboard intermediate rib feeds water evacuation channels that continue to the outboard shoulder, reducing hydroplaning for increased stability in wet conditions. Inclement weather traction is further enhanced by the HTR A/S P03's "Miura-Ori" sipes molded into the outboard rib, helping the tire maintain its connection to the road surface in wet and wintertime conditions. Cross-design grooves and sipes built into the inboard ribs further enhance road contact, with a focus on maximizing winter traction.The HTR A/S P03 features a robust, two-ply polyester casing designed to increase durability and maintain ride comfort. A twin-reinforced steel belt package further enhances reliability and is wrapped with a full-width nylon reinforcement to help maintain high speed integrity and stability.
