The present invention relates to a pneumatic tire with a sound-absorbing part formed in a groove of a tread, wherein in the pneumatic tire, a sound-absorbing part made of wedge-shaped sound-absorbing protrusions disposed in the horizontal and vertical directions is bundled in 2..n each in the groove of the tread, and has an effect of improving a resonance sound attenuation efficiency inside the tire by forming sound-absorbing protrusions in the groove of the tread to reduce, in advance, a noise generated when the tread of the tire collides with the air from the outside of the tire.

    본 발명은 트레드의 그루브에 흡음부를 형성한 공기입 타이어에 관한 것으로, 공기입 타이어에 있어서, 트레드의 그루브에 2..n개씩 묶어 가로와 세로방향으로 배치한 쐐기형 흡음돌기들로 이루어진 흡음부가 형성된 것으로, 트레드의 그루브 내에 흡음돌기들을 형성하여 타이어 외부에서 타이어의 트레드와 공기가 부딪혀 발생하는 소음을 미리 저감할 수 있도록 함으로써, 타이어 내부에서 공명음 감쇄 효율이 향상되도록 하는 효과가 있다.
