Claim 0:
1. A tire comprising:
a tread portion,
wherein the tread portion comprises at least one land portion,
wherein the land portion comprises an outer region disposed inwardly of a tread surface in a tire radial direction, an inner region disposed inwardly of the outer region in the tire radial direction, and at least one sipe,
wherein the at least one sipe comprises one outer sipe element extending in the outer region in a tire axial direction, and a plurality of inner sipe elements extending in the inner region,
wherein the plurality of inner sipe elements comprises a component extending in a tire circumferential direction, and is connected to the outer sipe element,
wherein the plurality of inner sipe elements comprises a plurality of bent elements, and
wherein each of the plurality of bent elements comprises:
a first offset element that is offset toward one side relative to the outer sipe element in the tire circumferential direction and that extends in the tire axial direction,
a second offset element that is offset toward another side relative to the outer sipe element in the tire circumferential direction and that extends in the tire axial direction, and
a joint element connecting between at least one of the first offset elements and at least one of the second offset elements,

wherein the joint element is inclined relative to the tire circumferential direction,
wherein in each of the plurality of bent elements:
the first offset element comprises a first terminating element extending toward the second offset element so as to be inclined relative to the tire circumferential direction in a direction opposite to a direction of the joint element, at an end portion on a side opposite to a side connecting to the joint element, and
the second offset element comprises a second terminating element extending toward the first offset element so as to be inclined relative to the tire circumferential direction in a direction opposite to the direction of the joint element, at an end portion on a side opposite to a side connecting to the joint element, and

wherein the plurality of bent elements are separate from each other and bent elements adjacent to each other in the tire circumferential direction partially overlap each other in the tire axial direction.
