Pneumatic tire

A pneumatic tire comprising a pair of bead portions, wherein

• a plurality of recesses arranged in a tire circumferential direction on an outer surface of at least one of the pair of bead portions,
• the plurality of recesses each including a sidewall surface extending inward in a tire axial direction from the outer surface, and a bottom surface defining a depth of the recess,
• in at least one recess of the plurality of recesses, in a cross-section of the recess including a tire rotation axis,
• the sidewall surface located on an outer side in a tire radial direction and the bottom surface are smoothly connected via an arc portion,
• the arc portion has a radius of curvature equal to or larger than the depth of the recess,
• each of the recesses is elongate in the tire circumferential direction,
• for each of the plurality of recesses, an intersection position between the sidewall surface and the outer surface is an obtuse angle, and an angle between the sidewall surface and a normal line that is normal to the outer surface at the intersection position is in a range of 10 to 30 degrees,
• the plurality of recesses each have an opening edge in the outer surface, the opening edge includes a first edge extending in the tire circumferential direction, a second edge extending in the tire circumferential direction on an inner side in the tire radial direction of the first edge, a pair of third edges extending in the tire radial direction between the first edge and the second edge, and a recess height that is a distance in the tire radial direction between the first edge and the second edge,
• the first edge is smoothly connected to each of the pair of third edges via a first arc edge, and
• for each of the plurality of recesses, a recess height is 1 to 10 times a radius of curvature of the first arc edge.
