The pneumatic tire according to this disclosure has at least two circumferential grooves extending continuously on a tread surface, and has a resonator disposed on a land portion partitioned by two circumferential grooves among the circumferential grooves, the resonator having an air chamber opening toward a land portion surface at a position spaced from the circumferential grooves, one a more one-side narrow necks connecting the air chamber to one circumferential groove of the two circumferential grooves, and one or more other-side narrow necks connecting the air chamber to the other circumferential groove, the one-side narrow neck and the other-side narrow neck having cross section areas approximately identical to each other, and an extending length of the one-side narrow neck and an extending length of the other-side narrow neck being different.",
