<p>A tire (1) is provided with multiple protrusions (500) in the bottom part (50B2) of a groove, with said protrusions (500) extending from one side wall (50B1) that forms a groove, to the other side wall (50B3) opposite the one side wall (50B1). Said protrusions (500) are provided at predetermined intervals in the groove. In the case where the length of the protrusions (500) is given as L and the predetermined intervals are given as P, a relationship is satisfied in which 0.75L = P = 10L. Also, in the case where a groove width is given as W, the width of the protrusions (500) is given as TWf, and an angle formed, in the tread surface view of the tire (1), between the groove center line (WL) and the extending direction (x) of the protrusions (500) and formed on the side opposite the rotation direction (tr1) of the tire (1) is given as ?f, a relationship is satisfied in which TWf/cos?f = 0.9W.</p> |
