PROBLEM TO BE SOLVED: To provide a pneumatic tire enhanced in controllability and stability and uneven wear resistant performance while substantially maintaining sufficient water discharge performance by a wide main groove and the noise performance of air column resonance sound. SOLUTION: In the pneumatic tire, one straight main groove 2 and two wave-shape main grooves 3 are arranged at a central area of a tread 1, an inclination groove 5 extending from the wave-shape main groove 3 to an oblique outer side in a tire counter-rotation direction is arranged at a position from the wave-shape main groove 3 to a shoulder area at an outer side of the tire, and a tire rotation direction is designated. The inclination groove 5 is formed into an arc shape becoming a projection to the outer side of the tire, an extension end of the inclination groove 5 is terminated in the shoulder area, and the shoulder area is formed into a non-block pattern in which a land is continued in a tire circumferential direction.
