The present invention relates to a pneumatic tire in which cavity resonance noise is reduced using a Helmholtz resonator. The pneumatic tire includes a tread unit (100), a side wall unit (200), and a bead unit (300). The pneumatic tire includes: a sound-absorbing member (500) attached to the inner surface of the tread unit (100); and a Helmholtz resonator (600) formed inside the sound-absorbing member (500).

    본 발명은 헬름홀쯔 공명기를 이용하여 공명소음(Cavity Resonance Noise)을 저감한 공기입 타이어에 관한 것으로서, 트레드부(100)와 사이드월부(200) 및 비드부(300)를 포함하여 구성되는 공기입 타이어에 있어서, 상기 트레드부(100)의 내측면에 부착되는 흡음부재(500); 및 상기 흡음부재(500)의 내부에 형성되는 헬름홀쯔 공명기(600);를 포함하여 구성되는 것을 특징으로 하는 공기입 타이어를 제공한다.
