A circumferential recess, which is formed on the inside in a tread width direction and extends in a tire circumferential direction, is formed on the outer surface of a tire side section. In a cross section in the tread width direction of the tire and the tire radial direction, a rim-side outer surface formed in an area from a rim separation point, which is the outermost point in the tire radial direction that is in contact with a rim flange, to the inner end of the circumferential recess in the tire radial direction, is formed along a first arc curve having a center of curvature of radius on the inside in the tread width direction. In the cross section, a sidewall surface formed in an area from the inner end of the circumferential recess in the tire radial direction to the bottom of the circumferential recess is formed along a second arc curve having a center of curvature of radius on the outside in the tread width direction. |
