Pneumatic tire

A pneumatic tire includes a plurality of circumferential grooves and a first land portion. The circumferential grooves extend continuously in a tire circumferential direction. The first land portion extends in the tire circumferential direction between a pattern end and one of the circumferential grooves in a shoulder region located outside the circumferential grooves in a tire width direction. The first land portion has first lug grooves extending from the pattern end in the tire width direction and closed without communicating with the circumferential grooves are arranged in the tire circumferential direction. At least one circumferential groove is wave-shaped with a constant groove width in the tire width direction at a tread surface and formed in a wave shape in the circumferential direction at the tread surface and groove bottom. The wave-shaped circumferential groove has a shorter cycle length of waves at the groove bottom than at the tread surface.
