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.
