发明名称 PNEUMATIC TIRE
摘要 PURPOSE:To improve the operational safety by forming a given asymmetric pattern in which the direction having the maximum and minimum shearing stiffness ratio and the maximum stiffness is made to be specified in tires mounted with a V-shaped pattern directed toward in the forward direction of a vehicle. CONSTITUTION:A tire tread pattern is formed left and right at a place of 70% of a ground width, and the left side formation is formed in which the maximum and minimum shearing stiffness ratio of 1.2-1.8 is to be obtained in the state where the direction having the maximum shearing stiffness of blocks 1 has a crossing angle of 60-80 deg. to a tire peripheral direction EE'. Blocks 1 of the remaining right side formation is formed in which the maximum and minimum shearing stiffness ratio of 1.2-1.8 is to be obtained in the state where the direction having the maximum shearing stiffness has a crossing angle of -60--80 deg. to the tire peripheral direction EE'. This asymmetric formation of the tred pattern and the mounting of a tire having a V-shaped pattern formed in the vehicle traveling direction enables the improvement in the operational safety.
