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 15):
The heavy duty pneumatic tire according to  claim 1 , wherein\n one of the first narrow grooves provided in each of the regions of adjacent center blocks of the plurality of center blocks adjacent in the tire circumferential direction opens to one of the plurality of center lug grooves at the same position so as to continuously extend on either side of the one of the plurality of center lug grooves; shoulder block regions on both sides in the tire width direction provided between adjacent shoulder lug grooves of the plurality of shoulder lug grooves adjacent in the tire circumferential direction comprise second narrow grooves having a narrower groove width than the plurality of shoulder lug grooves, the second narrow grooves terminating within the shoulder blocks and opening to one of the circumferential main grooves; the first narrow grooves provided in the adjacent center block regions and the second narrow grooves make a set that forms one continuous narrow groove extending through the shoulder block regions on the both sides; and L 4 /T ranges from 0.5 to 1.1, where L 4  is an entire groove length of the continuous narrow groove and T is the tread width of the tread portion in the tire width direction.
