The groove bottom protruding portions 7 each has a first groove bottom surface 8 extending radially and a second groove bottom surface 9 having an angle regarding the tyre radial direction larger than the first groove bottom surface 8. Groove walls 6 each includes groove wall protruding portions 11 protruding toward an inner side of the circumferential groove 3 from a groove wall reference surface (6A) as a surface along a tyre circumferential direction at a widest position of a groove width (w).
