The at least one circumferential groove includes a groove bottom having a plurality of protrusions projecting in a tyre radial direction. Each of the plurality of protrusions has a longitudinally elongated shape with a width in a tyre axial direction and a length in the tyre circumferential direction that is greater than the width. Each of the plurality of protrusions includes a tapered portion whose width decreases in the tyre circumferential direction.",
