发明名称 PNEUMATIC TIRE
摘要 PROBLEM TO BE SOLVED: To provide a pneumatic tire increased in wear resistance while maintaining high drainage property. SOLUTION: This pneumatic tire has, in a tread part 2, a plurality of main grooves 22 extending in the circumferential direction of the tire. The pneumatic tire satisfies the requirement 0.3(TW/2)≤L0≤0.6(TW/2) when a tire ground-contact width is TW and the length of the tire in the tire width direction from the side wall 22ba of the second main groove 22b on the outer side of the tire in the tire width direction to the equator C of the tire on the outermost side of the tire in the tire width direction is L0. The inner belt 71 among three belts 71, 72, 73 is configured as a low angle belt the sharp side angleθa of the cord thereof relative to the peripheral direction of the tire is within the range of 15°≤θa≤35°. The intermediate belt 72 is configured as a high angle belt the sharp side angleθb of the cord thereof relative to the peripheral direction of the tire is within the range of 50°≤θb≤90°. The outer belt 73 is configured as a high angle belt the sharp side angleθc of the cord thereof relative to the peripheral direction of the tire is within the range of 35°≤θc≤70°.
