| 摘要 |
A heavy duty pneumatic tire includes a tread portion provided with at least one circumferentially and continuously extending main groove, and a plurality of lateral grooves to form circumferentially repeated pitch elements each of which consists of one lateral groove and a block element divided between two adjacent lateral grooves. The tread portion has a land ratio in a range of from 70% to 80%, and the pitch elements in a range of from 40 to 50. Each lateral groove has a circumferential groove width 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. |
