A tread rubber forming the tread portion includes a first rubber layer and a second rubber layer. The second rubber layer has a complex elastic modulus smaller than a complex elastic modulus of the first rubber layer. The first groove includes a first groove edge, a groove bottom surface, and a first groove wall. In a lateral cross section of the first groove, the first groove wall includes a first wide top portion arranged between the first groove edge and the groove bottom surface and located outside the first groove edge in a groove width direction of the first groove.
