PROBLEM TO BE SOLVED: To provide a tire further enhancing durability. SOLUTION: The tire has a belt in which at least one layer of circumferential belt layer and inclination belt layers in which the cords inclined relative to a tire equator surface are arranged in directions crossed to each other are arranged in the order. Width of the wide inclination belt layer having the widest width of the inclination belt layers is 0.6 times or more of tire cross section width, and an end part in a tire width direction of the wide inclination belt layer is positioned at an outer side in the tire width direction than the end part in the tire width direction of the circumferential belt layer. An end part in the tire width direction of the inclination belt layer other than the wide inclination belt layer is positioned at an inner side in the tire width direction than the end part in the tire width direction of the circumferential belt layer. In the wide inclination belt layer, an inclination angle of the cord relative to the tire equator surface is made to 15°to less than 35°, and in at least one inclination belt layer adjacent to the wide inclination belt layer, an inclination angle of the cord relative to the tire equator surface is made to 40°to 60°.
