At least one of the land portion regions includes a first sipe and a second sipe disposed to be adjacent to the first sipe in the tire circumferential direction as the sipe, the sipe region being provided in at least a partial region in the tire width direction. A sipe width of the second sipe is wider than a sipe width of the first sipe. The sipe region is not provided with a lug groove having a wider groove width than the sipe width of the second sipe, the lug groove extending in the tire width direction.",
