发明名称 PNEUMATIC TIRE
摘要 PROBLEM TO BE SOLVED: To provide a pneumatic tire excellent in both fracture resistance and high speed durability.SOLUTION: A pneumatic tire includes a belt comprised of belt layers of at least two layers, and a code of at least an innermost belt layer positioned at an innermost side in a tire radial direction is bent so that angles to a tire circumferential direction are different at a center part in a tire width direction and an outer part in the tire width direction among the belt layers constituting the belt. An angle between the code of the innermost belt layer and the tire circumferential direction in the center part in the tire width direction is larger than that in the outer part in the tire width direction. In the code of the innermost belt layer, a twisting pitch of a part positioned at the center part in the tire width direction is smaller than that positioned at the outer part in the tire width direction and the twisting pitch of the part positioned at the center part in the tire width direction of the code of the innermost belt layer is smaller than those of the other belt layers.
