A tire comprising a tread portion, wherein the tread portion includes a first circumferential groove continuously extending in a tire circumferential direction, and a first land portion adjacent to a first side in a tire axial direction of the first circumferential groove, a groove bottom portion of the first circumferential groove includes a groove bottom reference surface and a plurality of projections projecting outwardly in a tire radial direction from the groove bottom reference surface, the first land portion has at least one first lateral groove extending from the first circumferential groove and terminating within the first land portion, and at least one second lateral groove fully traversing the first land portion, in a tread plan view, an entirety of a first lateral groove extension region obtained by extending a connection portion of the first lateral groove at the first circumferential groove to the groove bottom portion of the first circumferential groove so as to be parallel to the tire axial direction is formed on the groove bottom reference surface, which means that projections are not formed in the first lateral groove extension region, the first circumferential groove includes first inclined portions inclined relative to the tire circumferential direction and second inclined portions inclined at a larger angle relative to the tire circumferential direction than the first inclined portions, and the first inclined portions and the second inclined portions are provided alternately in the tire circumferential direction characterized in that in a tread plan view, at least a part of the projection overlaps a second lateral groove extension region obtained by extending a connection portion of the second lateral groove at the first circumferential groove to the groove bottom portion of the first circumferential groove so as to be parallel to the tire axial direction. the tread portion includes a first circumferential groove continuously extending in a tire circumferential direction, and a first land portion adjacent to a first side in a tire axial direction of the first circumferential groove, a groove bottom portion of the first circumferential groove includes a groove bottom reference surface and a plurality of projections projecting outwardly in a tire radial direction from the groove bottom reference surface, the first land portion has at least one first lateral groove extending from the first circumferential groove and terminating within the first land portion, and at least one second lateral groove fully traversing the first land portion, in a tread plan view, an entirety of a first lateral groove extension region obtained by extending a connection portion of the first lateral groove at the first circumferential groove to the groove bottom portion of the first circumferential groove so as to be parallel to the tire axial direction is formed on the groove bottom reference surface, which means that projections are not formed in the first lateral groove extension region, the first circumferential groove includes first inclined portions inclined relative to the tire circumferential direction and second inclined portions inclined at a larger angle relative to the tire circumferential direction than the first inclined portions, and the first inclined portions and the second inclined portions are provided alternately in the tire circumferential direction characterized in that in a tread plan view, at least a part of the projection overlaps a second lateral groove extension region obtained by extending a connection portion of the second lateral groove at the first circumferential groove to the groove bottom portion of the first circumferential groove so as to be parallel to the tire axial direction.
