Pneumatic tire

A pneumatic tire comprising

• a tread portion;
• a pair of sidewall portions each extending inwardly in a tire radial direction from both end portions of the tread portion;
• a bead portion formed on an inside of each of the sidewall portions in the tire radial direction;
• a plurality of shoulder blocks arranged in the tire circumferential direction with first pitches on at least one of the end portions of the tread portion;
• a plurality of side protectors protruding outwardly in a tire axial direction on at least one of the sidewall portions which is located on a side of the shoulder blocks;
• a recessed portion between a pair of side protectors adjacent in the tire circumferential direction;
• the side protectors being arranged in the tire circumferential direction with second pitches larger than the first pitches;
• and
• each of the side protectors being provided with one first groove extending inwardly in the tire radial direction from a side of the tread portion and terminating within the side protector and a pair of second grooves extending outwardly in the tire radial direction from a side of the bead portion and terminating within the side protector and provided on both sides in the tire circumferential direction of the first groove, wherein one of the second grooves disposed on one side of the first groove is connected with the recessed portion.
