Heavy duty pneumatic tire

摘要

A tread pattern is provided with: shoulder lug grooves (12A, 12B) open at ground contact ends (E1, E2); center lug grooves (14) each having opposite ends; circumferential primary grooves (11A, 11B) each formed in a wavy shape by connecting ends of center lug grooves (14) and the inner ends of shoulder lug grooves (12A, 12B) in the width direction of the tire; and center blocks (20) defined by the center lug grooves (14) and the pair of circumferential primary grooves (11A, 11B). The width of the circumferential primary grooves (11A, 11B) is smaller than the width of the shoulder lug grooves (12A, 12B). The center lug grooves (14) are tilted relative to both the circumferential direction and the width direction of the tire and each have a third groove bend (14a) and a fourth groove bend (14b), which protrude in the different directions in the circumferential direction of the tire.
