    Abstract: A pneumatic tire comprises a carcass layer, a belt layer disposed on an outer side of the carcass layer in a tire radial direction, and a tread rubber disposed on the outer side of the belt layer in the tire radial direction. The belt layer formed by laminating an angle belt having a belt angle ≥45° and ≤70° in absolute values, a pair of cross belts, having belt angles of ≥10° and ≤45° in absolute values and having belt angles of mutually opposite signs, and a circumferential reinforcing layer having a belt angle within a range of ±5° with respect to a tire circumferential direction. A tread width TW and a cross-sectional width Wca of the carcass layer have a relationship such that 0.82≤TW/Wca≤0.92. A width Ws of the circumferential reinforcing layer and a cross-sectional width Wca of the carcass layer such that 0.60≤Ws/Wca≤0.70.

    Abstract: Provided is a heavy duty pneumatic tire that includes a tread portion including, in a tread pattern: shoulder lug grooves extending outward in the tire width direction and opening at ground contact edges; a pair of circumferential primary grooves; center lug grooves; center blocks defined by the center lug grooves and the pair of circumferential primary grooves and aligned in the tire circumferential direction; and circumferential secondary grooves extending in the tire circumferential direction in the center block regions and opening to the center lug grooves adjoining the center blocks. The circumferential secondary grooves extend in the tire circumferential direction while changing positions in the tire width direction and each include third groove turning portions formed into a bent shape or a curved shape. The ratio P4/P1 of the width P4 of the circumferential secondary grooves to the width P1 of the circumferential primary grooves is from 0.70 to 1.10.

    Abstract: A pneumatic tire with improved heat build-up resistance in a land portion in a tread center region. The pneumatic tire is provided with a tread pattern that includes a plurality of center lug grooves (14) disposed at intervals in a tire circumferential direction that cross a tire equator line; a plurality of shoulder lug grooves (12A, 12B) disposed in intervals between the plurality of center lug grooves in the tire circumferential direction extending outward in the tire width direction, an inner end in the tire width direction being disposed outward of an end of the center lug groove in the tire width direction; a pair of circumferential primary grooves (11A, 11B) extending around an entire circumference of the pneumatic tire in a wave-like shape with the ends of the center lug grooves and the inner ends of the plurality of shoulder lug grooves in the tire width direction alternately connecting to the pair of circumferential primary grooves (11A, 11B); and a circumferential secondary groove (10) disposed on the tire equator line around the entire circumference of the pneumatic tire that intersects the center lug grooves. A straight line that joins an intersection portion between the center lug groove and the circumferential secondary groove and the end of the center lug groove has an inclination angle with respect to the tire circumferential direction ranging from 55° to 75°.
