January 29, 2025
A pneumatic tire includes a tread portion 2. The tread portion 2 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 8 including a band cord 10 is included inside the tread portion 2. The band cord 10 is a steel cord including a plurality of steel filaments 12. A filament occupancy ratio Fs of the band cord 10 disposed closest to the tread end Te in the band layer 8 is 0.15 to 0.50. A product of an average number Ea of the band cords 10 arranged in the band layer 8 per 5 cm in a tire width direction (cords/5 cm) and a total ΣSf of cross-sectional areas of the plurality of steel filaments 12 is not less than 5.
