A tire (2) according to the present invention includes a belt (14) in which an inner layer (36) and an outer layer (38) each include multiple cords which are formed from steel and aligned with each other; the percentage of the volume of the cords to the total volume of the belt (14) is greater than or equal to 11% and not greater than 14%; preferably, an absolute value of a tilt angle (±i) of each cord (40) relative to the circumferential direction in a center portion of the inner layer (36) is less than an absolute value of a tilt angle (²i) of each cord (40) relative to the circumferential direction in shoulder portions of the inner layer (36); the difference between the angle (±i) and the angle (²i) is greater than or equal to 1.5° and not greater than 2.5°; an absolute value of a tilt angle (±o) of each cord (44) relative to the circumferential direction in a center portion of the outer layer (38) is less than an absolute value of a tilt angle (²o) of each cord (44) relative to the circumferential direction in shoulder portions of the outer layer (38); a difference between the angle (±o) and the angle (²o) is greater than or equal to 1.5° and not greater than 2.5°.
