Abstract:
A heavy duty pneumatic tire comprises a tread pattern that comprises: circumferential main grooves with a wave-like shape, shoulder lug grooves extending in the tire width direction to a ground contact edge and connecting to the circumferential main grooves at first groove turning portions that protrude outward; center lug grooves connecting to the circumferential main grooves at second groove turning portions that protrude inward; and center blocks defined by adjacent center lug grooves of the center lug grooves adjacent in the tire circumferential direction and the circumferential main grooves, forming a row in the tire circumferential direction. The center lug grooves and the circumferential main grooves have a narrower groove width than the shoulder lug grooves; and each region of the center blocks includes two first narrow grooves having a curved line shape with no bent portions and having a narrower groove width than the shoulder lug grooves.

Claim (Index 1):
A heavy duty pneumatic tire, comprising\n a tread pattern comprising: a plurality of center lug grooves with a linear shape disposed at intervals in a tire circumferential direction that extend at an incline with respect to a tire width direction and the tire circumferential direction in half-tread regions on a first side and a second side in the tire width direction with respect to a tire equator line so as to cross the tire equator line, the center lug grooves having ends in the first side and the second side; a plurality of shoulder lug grooves disposed at intervals in the tire circumferential direction in both of the half-tread regions that extend outward in the tire width direction, with outer ends in the tire width direction that open to ground contact edges on both sides in the tire width direction, inner ends of the plurality of shoulder lug grooves in the tire width direction being located outward in the tire width direction of the ends of the plurality of center lug grooves, and in the tire circumferential direction, one of the plurality of shoulder lug grooves being disposed between adjacent center lug grooves of the plurality of center lug grooves adjacent in the tire circumferential direction; a pair of circumferential main grooves formed in both of the half-tread regions with a wave-like shape in the tire circumferential direction, with first groove turning portions that curve or bend outward in the tire width direction and second groove turning portions that curve or bend inward in the tire width direction disposed so that the pair of circumferential main grooves alternately connect to the ends of the plurality of center lug grooves and the inner ends of the plurality of shoulder lug grooves in the tire width direction, the plurality of shoulder lug grooves opening to the pair of circumferential main grooves at the first groove turning portions and the plurality of center lug grooves opening at the second groove turning portions; and a plurality of center blocks defined by the adjacent center lug grooves of the plurality of center lug grooves adjacent in the tire circumferential direction and the pair of circumferential main grooves, forming a row in the tire circumferential direction; the plurality of center lug grooves and the pair of circumferential main grooves having a narrower groove width than the plurality of shoulder lug grooves; and each region of the plurality of center blocks comprising two first narrow grooves having a curved line shape with no bent portion and having a narrower groove width than the plurality of shoulder lug grooves, each of the first narrow grooves opening to one of the pair of circumferential main grooves and opening to one of the adjacent center lug grooves.
