Abstract

See full text

A pneumatic tire includes a carcass layer and belt layers including belt cords inclined with respect to a circumferential direction, the belt cords of different layers being arranged in a criss-cross manner. In at least one belt layer, an inclination angle α of the belt cords with respect to the circumferential direction at a center position and an inclination angle β of the belt cords with respect to the circumferential direction at a belt end position satisfy 15°≤β<α≤35°. A maximum ground contact length L1 and a ground contact length L2 satisfy 0.8≤L2/L1≤1.0, where L1 is the maximum ground contact length in the circumferential direction, W1 is a maximum ground contact width in a radial direction, and L2 is the ground contact length in the circumferential direction at a position 40% of W1 from the center position outward in a lateral direction.
