Abstract
A tire comprises a tread portion. The tread portion is provided with a sipe. The sipe comprises four sipe segments: a first sipe segment, a second sipe segment, a third sipe segment, and a fourth sipe segment. At least one of the first sipe segment and the third sipe segment comprises an oscillated portion which extends in the radial direction of the tire, while oscillating in a lateral direction orthogonal to the length direction of the sipe in a cross section of the sipe orthogonal to the length direction. Each of the first sipe segment and the third sipe segment comprises the oscillated portion including an oscillating-start portion, and the oscillating-start portion of the first sipe segment is inclined with respect to the tire radial direction in the same direction as the oscillating-start portion of the third sipe segment.
