Passenger EV tire performance optimization through integral-approach: Construction, tread-pattern, compound

Optimization of Passenger EV Tire performance by connecting three dots: Tire Construction, Tread-Pattern & Compounds. The major challenges are high instant torque, higher weight and longer breaking distance. Unique requirements: Stronger-Carcass, Higher-Durability, Low-RR, Reduced-Noise and High-Grip. Reinforced shoulder, multi-layer carcass and stiffer Sidewall-Region provides higher Structural-Strength. High-Grip & Improved-Aquaplaning, Reduced-Noise and Lower-RR achieved by Asymmetric Directional Tread-Pattern, Variable Pitch with special Sipes and Larger-Footprint with uniform pressure distribution respectively Blends of Natural Rubber Carbon Black and Silica-Silane compounds together with resin system provides robust, durable, low RR and high grip tread. Resin-reinforced Carbon-silica sidewall and apex compounds provides higher Stiffness.
