A tread pattern of a pneumatic tire comprises shoulder lug grooves that open to ground contact edges; center lug grooves; a pair of circumferential primary grooves with a narrower groove width than the shoulder lug grooves, wherein a portion that bends outward in the tire width direction connects to the shoulder lug grooves and a portion that bends inward in the tire width direction connects to the center lug grooves; and center blocks defined by the center lug grooves and the circumferential primary grooves. The circumferential primary grooves are on opposite sides in the tire width direction in regions spaced from a center line by a distance of from 30% to 60% of half of a tread width T. The ratio of the groove width P3 of the center lug grooves to the maximum length LB in the tire circumferential direction of the center blocks is from 0.03 to 0.07.
