Pneumatic tire

A pneumatic tire provided with a tread pattern, comprising:

• a plurality of circumferential grooves extending continuously in a tire circumferential direction;
• and
• a first land portion formed between a pattern end and one of the circumferential grooves in a shoulder region which is located outside the circumferential grooves in a tire width direction;
• the first land portion extending in the tire circumferential direction and including a plurality of first lug grooves arranged in the tire circumferential direction, the first lug grooves extending from the pattern end in the tire width direction and being closed without communicating with the circumferential grooves;
• and
• at least one of the circumferential grooves being a wave-shaped circumferential groove having a constant groove width in the tire width direction at a tread surface, the wave-shaped circumferential groove being formed in wave shapes in the tire circumferential direction at the tread surface and at a groove bottom, and the wave-shaped circumferential groove having a shorter cycle length of waves at the groove bottom than a cycle length of waves at the tread surface when the tire is new.
