Claim 0:
1. A pneumatic tire comprising a tread having a tread surface that comes in contact with a ground, wherein:
the tread comprises a plurality of main grooves including a first main groove that extends in straight fashion in a tire circumferential direction, and at least one first recess that is recessed toward a first side in a tire axial direction from the first main groove and that is arranged at a portion in the tire circumferential direction of the first main groove;
the at least one first recess comprises a first recess side face that is planar and that extends toward an interior in a tire radial direction from the tread surface, and a first recess bottom that is planar and that extends toward the first side in the tire axial direction from the first main groove so as to intersect the first recess side face;
the tread further comprises at least one second recess that is recessed toward a second side in the tire axial direction from the first main groove and that is arranged at a portion in the tire circumferential direction of the first main groove;
the at least one second recess comprises a second recess side face that is planar and that extends toward the interior in the tire radial direction from the tread surface, and a second recess bottom that is planar and that extends toward the second side in the tire axial direction from the first main groove so as to intersect the second recess side face;
the first main groove comprises a pair of groove side faces that are separated in the tire axial direction;
the pair of groove side faces include a first groove side face which is arranged toward the first side in the tire axial direction, and a second groove side face which is arranged toward the second side in the tire axial direction;
the first groove side face comprises at least one first inner side face portion, and at least one first outer side face portion which is arranged toward the first side in the tire axial direction from the at least one first inner side face portion;
the second groove side face comprises at least one second inner side face portion, and at least one second outer side face portion which is arranged toward the second side in the tire axial direction from the at least one second inner side face portion;
the at least one first recess is arranged at the at least one first outer side face portion;
the at least one second recess is arranged at the at least one second outer side face portion;
each of the at least one first inner side face portion and the at least one second inner side face portion extends from the tread surface towards a groove bottom in the tire radial direction;
the first main groove comprises at least one first region, at least one second region, at least one third region, and at least one fourth region;
the at least one first region is made up of the at least one first inner side face portion and the at least one second inner side face portion;
the at least one second region is made up of the at least one first outer side face portion and the at least one second inner side face portion;
the at least one third region is made up of the at least one first inner side face portion and the at least one second outer side face portion; and
the at least one fourth region is made up of the at least one first outer side face portion and the at least one second outer side face portion.
