Abstract:
To provide a tire capable of showing excellent on-ice performance and uneven wear performance.SOLUTION: A tread part is provided with a sipe 8, and four sipe pieces 10 of the sipe 8 include a first sipe piece 11, a second sipe piece 12, a third sipe piece 13 and a fourth sipe piece 14. AT least either the first sipe piece 11 or the third sipe piece 13 includes an amplitude part amplified in a horizontal direction orthogonal to a longitudinal direction and extending in a tire radial direction on a cross section orthogonal to the longitudinal direction. Each of the first sipe piece 11 and the third sipe piece 13 includes the amplitude part, and the amplitude part includes an amplitude start part.
