PROBLEM TO BE SOLVED: To provide a tire that suppresses temperature elevation of rubber in a tire side section, particularly, in a bead section side while reducing a manufacturing cost.SOLUTION: A pneumatic tire 1 includes a tread section and a tire side section continuing from the tread section. On an outer surface of the tire side section, a circumferential recess which is recessed inward in a tread width direction and extends in a tire circumferential direction, is formed; and a block is formed inside the circumferential recess. On a cross section along the tread width direction of the tire and a 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 an inner end of the circumferential recess in the tire radial direction is formed along a predetermined arc curve having a center of curvature of radius on an inside in the tread width direction. When an imaginary line extending the predetermined arc curve to the circumferential recess, at least a part of the block protrudes further to an outside in the tread width direction than the imaginary line. |
