A pneumatic tire includes a circumferentially continuous recess in at least one sidewall outer surface. In a meridian cross-section, an area A of a region surrounded by outlines of the sidewall and a bead and a tangent line, an area S of a region surrounded by the outlines of the sidewall and the bead, a carcass body, a perpendicular line L2, a perpendicular line L3, and a thickness G1 of a bead filler measured along the perpendicular line L2 satisfy 0.10(G117)A/(S+A)0.05(G110), the tangent line being straight and contacting the outlines of the sidewall and the bead, a contact point being where the tangent line and the sidewall outline contact, the perpendicular line L2 being straight and passing through a turned-up edge of a carcass and perpendicularly intersecting the carcass body, the perpendicular line L3 being straight and passing through the contact point and perpendicularly intersecting the carcass body.

A tire can include a pair of beads, a carcass, a pair of protective rubber layers, and a pair of reinforcing rubber layers. A carcass ply of the carcass can include a ply body and a pair of turned-up portions. Each reinforcing rubber layer can be between the turned-up portion and the protective rubber layer. An outer end of an apex of each bead can be between an outer end and an inner end of the reinforcing rubber layer in a radial direction. A thickness of the protective rubber layer in a zone from a rim contact end to the outer end of the reinforcing rubber layer can be small at a center portion in the radial direction of the reinforcing rubber layer and can be large at another portion.

In a pneumatic tire, a rubber occupancy ratio in a closed region is in a range of 15% or less. Bead cores have a predetermined wire arrangement structure formed by arranging wire cross sections of bead wires in a cross-sectional view in a tire meridian direction. A tangential contacts an innermost layer in a tire radial direction and the wire cross sections innermost and outermost in a tire lateral direction in the wire arrangement structure from a rim fitting surface side. Contact points of the tangent line are on the innermost and outermost wire cross sections. A gauge is in the tire lateral direction from the midpoint to the rim fitting surface. A rate of change of the gauge between before and after mounting on a rim is in a range from 10% or greater to 60% or less.
