发明名称 TIRE OF VEHICLE FOR LOW RESISTANCE TO ROTATION
摘要 PURPOSE: A tire for low rotation resistance in a vehicle is provided to improve driving experience, and to minimize the resistance of the tire to rotation by forming the tread with a compound including different kinds of rubber. CONSTITUTION: A tread portion of a tire is formed of a rubber compound including different kinds of materials from a center(4) to a shoulder portion(3). A tangent value of phase difference between internal stress and strain is reduced from the center to the shoulder portion in applying load repeatedly. The tangent value is obtained with subtracting elastic modulus in unloading from elastic modulus in loading and dividing the value by the elastic modulus in loading. The resistance to rotation is minimized with decreasing the tangent value to the shoulder portion.
