Kind Code:
A1
Abstract:
Provided is a pneumatic tire that sufficiently achieves both low rolling resistance and noise performance during high-speed travel. 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 regulation rim and with an internal pressure of 250 kPa, satisfy (formula 1) and (formula 2) below. (Formula 1): e / (0.31 Wt + 14.35) > 1; (Formula 2): e / (0.31 Wt + 56.45) < 1
