Abstract
A pneumatic tire comprises a tread surface comprising main grooves extending in a tire circumferential direction, at least two of the main grooves adjacent in the tire circumferential direction having a wave shape with periodic oscillation; adjacent land portions in a tire lateral direction formed by the main grooves; lug grooves disposed in a row in the tire circumferential direction in the land portion formed between the wave-shaped main grooves, the lug grooves intersecting the tire circumferential direction and communicating with the wave-shaped main grooves at both ends; and narrow grooves disposed between pairs of the lug grooves adjacent in the tire circumferential direction in a row in the tire circumferential direction, the narrow grooves intersecting the tire circumferential direction, communicating with one of the main grooves at a first end, terminating within the land portion at a second end, and having a narrower groove width than the lug grooves.
