A pneumatic tire comprising a tread portion, wherein the tread portion has a ground-contact surface in which a center portion in a tire axial direction projects outward in a tire radial direction with respect to each tread end (Te), a band layer including a band cord helically wound in a tire circumferential direction is included inside the tread portion, the band cord is a steel cord including a plurality of steel filaments, a filament occupancy ratio (Fs) of the band cord disposed closest to the tread end (Te) in a tire cross-sectional view including a tire rotation axis is represented by a ratio ΣSf/Sv of a total ΣSf (mm 2) of cross-sectional areas of the plurality of steel filaments and an area Sv (mm 2) of a smallest virtual circle that can completely enclose the plurality of steel filaments, and is 0.15 to 0.50, and a product (Ea*ΣSf) of an average number Ea of the band cords arranged in the band layer per 5 cm in a tire width direction (cords/5 cm) and the total ΣSf of the cross-sectional areas of the plurality of steel filaments is not less than 5; wherein the tread portion includes a crown region on the tire equator plane side, a shoulder region on the tread end (Te) side, and a middle region between the crown region and the shoulder region, in the tire cross-sectional view, the band layer includes a plurality of band cords (10c, 10m, 10s) disposed in the crown region, the middle region, and the shoulder region, and the filament occupancy ratio (Fs) of the band cord disposed in the crown region is larger than the filament occupancy ratio (Fs) of the band cord disposed in the shoulder region. the tread portion has a ground-contact surface in which a center portion in a tire axial direction projects outward in a tire radial direction with respect to each tread end (Te), a band layer including a band cord helically wound in a tire circumferential direction is included inside the tread portion, the band cord is a steel cord including a plurality of steel filaments, a filament occupancy ratio (Fs) of the band cord disposed closest to the tread end (Te) in a tire cross-sectional view including a tire rotation axis is represented by a ratio ΣSf/Sv of a total ΣSf (mm 2) of cross-sectional areas of the plurality of steel filaments and an area Sv (mm 2) of a smallest virtual circle that can completely enclose the plurality of steel filaments, and is 0.15 to 0.50, and a product (Ea*ΣSf) of an average number Ea of the band cords arranged in the band layer per 5 cm in a tire width direction (cords/5 cm) and the total ΣSf of the cross-sectional areas of the plurality of steel filaments is not less than 5; wherein the tread portion includes a crown region on the tire equator plane side, a shoulder region on the tread end (Te) side, and a middle region between the crown region and the shoulder region, in the tire cross-sectional view, the band layer includes a plurality of band cords (10c, 10m, 10s) disposed in the crown region, the middle region, and the shoulder region, and the filament occupancy ratio (Fs) of the band cord disposed in the crown region is larger than the filament occupancy ratio (Fs) of the band cord disposed in the shoulder region.
