In a tire 2, a band 22 includes a band cord 52, and a load at 4% elongation of the band cord 52 is not less than 60 N. A shape index of a ground-contact surface 60 obtained when the tire 2 is mounted on a normal rim, an internal pressure of the tire 2 is adjusted to a normal internal pressure, a normal load is applied to the tire 2, and the tire 2 is brought into contact with a road surface at a camber angle of 0°, is represented by a ratio of a length L0 of the ground-contact surface 60 at an axial center of the ground-contact surface 60 to a length L80 of the ground-contact surface 60 at a position at which a distance from the axial center of the ground-contact surface 60 is 0.8 times a distance in an axial direction from the axial center of the ground-contact surface 60 to an axially outer end of the ground-contact surface 60, and the shape index is not less than 1.40 and not greater than 1.44.
