TIRE

A pneumatic tire includes a carcass portion extending through a tread portion, a tire side portion, and a bead portion. The carcass portion includes a main portion, and a fold back portion fold back around a bead core. A circumferential depressed portion extended along a tire circumferential direction is formed on an outer surface of the tire side portion. On a tire cross-sectional plane, a rim-side outer surface formed in a range from a rim separation point to an inner-side end of the circumferential depressed portion along a tire radial direction is formed along a given circular-arc curved line. When a virtual circular-arc curved line drawn by extending the given circular-arc curved line is defined, a depth of the circumferential depressed portion with reference to the virtual circular-arc curved line is not smaller than 5mm and not larger than 35mm in a range of not smaller than 22% and not larger than 28% of a tire height from an bead end.
