Zusammenfassung:	The present invention relates to a pneumatic tire. In the pneumatic tire in which equal to or more than one longitudinal groove having the floor surface and side wall surfaces facing each other with the floor surface in between on the tread surface, a knurling unit consisting of equal to or more than one molded unit structure protruding in relief at a predetermined height starting from the side wall surface and extending to the floor surface are repeatedly arranged in the circumferential direction of the tire. According to the present invention, the knurling unit of a special shape is formed within the groove, thereby reducing a peak of a pipe resonating sound. Therefore, a noise generated during tire traveling is reduced and a noise performance is improved. 본 발명은 트레드 표면에 바닥면과 바닥면을 사이에 두고 서로 마주보는 측벽면을 갖는 하나 이상의 종그루브가 형성된 공기입 타이어에 있어서, 상기 측벽면에서 시작하여 바닥면으로 이어지는 소정의 높이로 양각으로 돌출된 하나 이상의 형 단위 구조로 구성되는 널링부가 타이어의 둘레방향으로 반복 배열되어 있는 것을 특징으로 하는 공기입 타이어에 관한 것으로, 본 발명의 공기입 타이어에 의하면 그루브 내에 특수한 형상의 널링부를 형성하여 파이프 공명음의 피크를 감소시킴으로써 타이어 주행 시 발생하는 소음을 저감시켜 노이즈 성능을 향상시키는 뛰어난 효과를 제공한다.
