The groove bottom 5 is provided with groove bottom raised portions 7 protruding radially outwardly from a reference plane 5a. The groove bottom raised portions 7 are a first groove bottom raised portion 7A located on a first side s1 in the width direction of the circumferential groove 3 and a second groove bottom raised portion 7B located on a second side s2 in the width direction. The first and second groove bottom raised portions 7A and 7B each comprise a plurality of repeating units 10 comprising a first bottom surface 8 extending substantially in the tire radial direction and a second bottom surface 9 inclined with respect to the tire radial direction at a larger angle than the first bottom surface 8.
