Abstract

An outer surface 2G of a tire 2 includes a tread surface 22 and a pair of side surfaces 26. A position, on the tread surface 22, at which a distance in an axial direction from an equator plane is 60% of a distance in the axial direction from the equator plane to a reference ground-contact position PH, is a tilt confirmation position P60. An angle of a tangent line that is tangent to a contour line of the tread surface 22 at the tilt confirmation position P60 with respect to the axial direction in a meridian cross-section is not less than 2.5 degrees and not greater than 3.5 degrees. A ratio of an equator ground-contact length measured along the equator plane to a reference ground-contact length at a position corresponding to a width of 60% of a ground-contact width of a ground-contact surface, on the ground-contact surface, is a shape index F60, and the shape index F60 is not less than 1.00 and not greater than 1.20.
