Abstract:
A first inside widthwise-direction groove (16i) which opens to a circumferential-direction groove (14a) is arranged in the tire circumferential direction on at least one side of a tread section (10). The first inside widthwise-direction groove (16i) is provided with: a widthwise-direction linear groove (16is) that linearly extends from the circumferential-direction groove (14c) in the tire widthwise direction; and a curved groove (16ir) which connects to the inside end in the tire widthwise direction of the widthwise-direction linear groove (16is), extends toward the inside in the tire widthwise direction, extends in the tire forward rotation direction (R), and reaches the tire equator line (CL). In addition, the angle (θ1) formed between the curved groove (16ir) and the tire widthwise direction (W) becomes smaller in a direction toward the tire equator line.
