A heavy duty pneumatic tire includes a tread portion (2) provided with at least one circumferentially and continuously extending main groove (3), and a plurality of lateral grooves (7) to form circumferentially repeated pitch elements P, each of which consists of one lateral groove and a block element (10) arranged between two adjacent lateral grooves. The tread portion has a land ratio in a range of from 70% to 80%, and a number of pitch elements in a range of from 40 to 50. Each lateral groove has a circumferential groove width W2 in a range of from 5% to 15% in relation to a circumferential length of the pitch element, and an angle in a range of from 45 to 85 degrees with respect to a circumferential direction of the tire. |
