The groove (110) includes a groove bottom surface (113) spaced apart by a predetermined distance from the tread surface in a radial direction of the pneumatic tire; and a plurality of groove side surfaces (112, 111) connected to the groove bottom surface (113) and each including a connection curved surface having a predetermined curvature. Each of the noise reflectors includes a support surface (210) supported by the connection curved surface and the groove bottom surface (113); and a protrusion surface (220) located on a side opposite to the support surface (210) and disposed to be spaced apart from the connection curved surface.",
