The circumferential groove 3 includes a first groove wall defining a side wall surface of the land portion 4. The land portion 4 includes a ground-contact surface connected to the first groove wall. A longitudinal hole and two or more lateral holes are provided in the land portion 4. The longitudinal hole has a longitudinal hole opening having a closed contour on the ground-contact surface and extends inward in a tire radial direction from the longitudinal hole opening. Each lateral hole has a lateral hole opening having a closed contour on a surface of the first groove wall and extends in a tire axial direction from the lateral hole opening so as to communicate with the longitudinal hole.",
