More Information
Summary:A heavy-duty pneumatic tire includes a tread having main grooves and lateral grooves connecting the main grooves such that each main groove has zigzag pattern extending continuously in tire circumferential direction and that the lateral grooves divide portion between the main grooves into blocks. Each main groove has a groove periphery on block side such that the groove periphery has inward crests protruding toward the block side and outward crests protruding in the opposite direction and alternating with the inward crests, the lateral grooves connect the inward crests and incline at angle α in range of 10 to 20 degrees with respect to tire axial direction, and each block is formed to have a ground-contact surface which has substantially hexagonal shape and ratio W2/W1 in range of 0.85 to 0.95 where W2 represents tire axial minimum width and W1 represents tire axial maximum width in the ground-contact surface.
