Abstract: A pneumatic tire includes a tread, a pair of sidewalls extending from edges of the tread substantially in a radially inward direction, a pair of clinches extending from edges of the sidewalls substantially in the radially inward direction, a pair of beads positioned on axially inner sides of the clinches, and a carcass extending along an inner side of the tread and sidewalls such that the carcass is bridging the pair of beads. Each bead includes a fitting portion extending in a circumferential direction and formed to be fitted to a rim, the fitting portion has a bottom surface positioned on a radially inner side of the fitting portion and a side surface positioned on an axially outer side of the fitting portion, the bottom surface includes a heel on the axially outer side of the fitting portion, and the side surface includes a concave extending in the circumferential direction.
