A first inner widthwise groove (16i) which opens to a circumferential groove (14a) is arranged in the tire circumferential direction on at least one side of a tread portion (10). The first inner widthwise groove (16i) is provided with a widthwise linear groove (16is) that linearly extends from the circumferential groove (14c) in the tire widthwise direction, and a curved groove (16ir) which connects to the inner end in the tire widthwise direction of the widthwise linear groove (16is), extends inward in the tire widthwise direction, extends in the tire normal rotation direction (R), and reaches the tire equator line (CL). In addition, the angle (¸1) formed between the curved groove (16ir) and the tire widthwise direction (W) becomes smaller in a direction toward the tire equator line.
