One embodiment of the present invention provides a noise reduction tire that reduces noise generated by air column resonance generated in a main groove and prevents a surface layer from becoming rough during mold casting by forming a fluid flow path. According to an embodiment of the present invention, a noise reduction tire includes a plurality of blocks formed on a tread, a groove formed between the blocks and formed to extend in a circumferential direction of the tire, a protruding portion including a plurality of protrusions formed to protrude on a bottom surface and a wall surface of the groove and extending along the groove, and a fluid flow path, and a dividing member formed along a wall surface of the groove and traversing the protruding portion to divide the protruding portion so as to move the fluid located in the protruding portion.

    本发明的一实施例提供了一种降噪轮胎,其减少因主凹槽中产生的气柱共鸣而产生的噪声并且通过形成流体流路来防止在模具铸造过程中表面层变得粗糙。根据本发明的实施例,降噪轮胎包括:多个块体,形成在胎面上,凹槽,形成在所述块体之间并且形成为沿轮胎的圆周方向延伸,突起部,包括形成为在所述凹槽的底面和壁面上突出并沿所述凹槽延伸的多个突起,以及流体流路,沿所述凹槽的壁面形成,横穿所述突起部以分割所述突起部,从而使位于所述突起部的流体移动。
