1. A tire comprising a first side block that protrudes in a tire axial direction from a sidewall reference surface, wherein:
the first side block comprises a first recess which opens so as to be directed toward a first circumferential direction, and a second recess which opens so as to be directed toward a second circumferential direction which is opposite the first circumferential direction in a tire circumferential direction;
the first recess comprises a first outer recess edge which is inclined with respect to a tire radial direction, and a first inner recess edge which is inclined with respect to the tire radial direction and which is arranged toward an interior in the tire radial direction from the first outer recess edge;
the first outer recess edge extends so as to be increasingly disposed in the first circumferential direction as one proceeds toward an exterior in the tire radial direction;
the first inner recess edge extends so as to be increasingly disposed in the first circumferential direction as one proceeds toward the interior in the tire radial direction;
the second recess comprises a second outer recess edge which is inclined with respect to the tire radial direction, and a second inner recess edge which is inclined with respect to the tire radial direction and which is arranged toward the interior in the tire radial direction from the second outer recess edge;
the second outer recess edge extends so as to be increasingly disposed in the second circumferential direction as one proceeds toward the exterior in the tire radial direction;
the second inner recess edge extends so as to be increasingly disposed in the second circumferential direction as one proceeds toward the interior in the tire radial direction;
the first side block comprises a first region, a second region, and a first step which is between the first region and the second region and which is formed by a difference in heights by which the first region and the second region protrude;
the first region is arranged toward the interior in the tire radial direction from the second region;
the first region comprises a first apical surface which is an outer surface in the tire axial direction;
the second region comprises a second apical surface which is an outer surface in the tire axial direction;
the first step comprises a first connecting surface which connects the first apical surface and the second apical surface;
the first connecting surface comprises a first contiguous portion which is contiguous with the first apical surface, and a second contiguous portion which is contiguous with the second apical surface;
a height by which the first contiguous portion protrudes is greater than a height by which the second contiguous portion protrudes;
the first recess is arranged so as to extend across the first region and the second region; and
the second recess is arranged at a location which is in the first region but is separated from the second region.
