PNEUMATIC TIRE

Provided is a pneumatic tire that sufficiently achieves both low rolling resistance and noise performance during high-speed running. The present invention is a pneumatic tire comprising a tread section and a belt layer, wherein monofilament cords are used as reinforcing cords in the belt layer, and an arranged number e of the monofilament cords per 5 cm in the tire-width direction (cords/5 cm) in a tire radial direction cross-section of the belt layer, and a tire cross-sectional width Wt (mm), incorporated in a standardized rim and with an internal pressure of 250 kPa, satisfy (formula 1) and (formula 2) below. e/ (0.31Wt + 14.35) > 1 (formula 1); e/ (0.31Wt + 56.45) (formula 2)
