WIPO Patent Application WO/2023/105877

A1

A tire according to the present invention comprises a circumferential groove extending along the tire circumferential direction in the tread surface and a tread ridge section demarcated on one side in the tire width direction by the circumferential groove. A resonator is arranged in the tread ridge section. The resonator opens at the surface of the tread ridge section and comprises an air chamber groove terminating within the tread ridge section and a neck groove that is narrower than the air chamber groove and whereby the air chamber groove and the circumferential groove communicate. The opening angle formed in a developed view of the tread surface by a first wall of the air chamber groove having one side wall of the neck groove connected thereto and a second wall of the air chamber groove having the other side wall of the neck groove connected thereto is 170º-200º. The air chamber groove is inclined with respect to the tire width direction and the tire circumferential direction. The length of extension of the air chamber groove in the tire circumferential direction is longer than the length of extension of the air chamber groove in the tire width direction.
