A pneumatic tire comprises a tread portion 2 provided with shoulder axial grooves 10 extending from a shoulder main groove 3 to a tread edge Te while inclining to a first-side in the tire circumferential direction. The shoulder axial groove 10 has a first-side groove edge, a second-side groove edge, a first-side groove-sidewall 14 extending radially inward from the first-side groove edge 12, and a second-side groove-sidewall 15 extending radially inward from the second-side groove edge 13. The shoulder axial groove 10 has a part where the inclination angle ² of the first-side groove-sidewall 14 with respect to a normal line passing through the first-side groove edge 12 perpendicularly to the tread surface 2s is more than the inclination angle ± of the second-side groove-sidewall 15 with respect to a normal line passing through the second-side groove edge 13 perpendicularly to the tread surface 2s. |
