A tread pattern of a heavy duty pneumatic tire includes: a linear shaped center lug groove; a pair of circumferential main grooves formed in a wave shape in a tire circumferential direction; a center block; and a central narrow groove that does not have a linear shape, having an opening end that opens in the adjacent center lug grooves in a tire lateral direction position excluding on a tire equator line, and having a groove width that is narrower than the groove width of the shoulder lug groove. The groove width of the center lug groove and the circumferential main groove is narrower than the groove width of the shoulder lug groove. The central narrow groove has a portion that extends outwards in a tire lateral direction from the opening end in the half tread region where the opening end is positioned.
