PNEUMATIC TIRE

To effectively reduce the air resistance of a vehicle while suppressing the deterioration in air resistance of the protrusions and the increase in rolling resistance of the tire. The pneumatic tire (1) having a vehicle inner/outer orientation when mounted on a vehicle includes: a plurality of protrusions (9) provided on a vehicle inner side on a tire side portion (S) in a tire circumferential direction; and a plurality of recesses provided on a vehicle outer side on a tire side portion (S), wherein the height of projection of the protrusions (9) from the tire side portion (S) is more than 4 mm and not more than 10 mm, the protrusions are formed elongated and the bending rigidity in a lateral direction satisfies a range not less than 0.1 MPa · mm 4 and not more than 10,000 MPa · mm 4 .
