August 17, 2011
The present invention enhances noise performance and anti-uneven wear performance. A pneumatic tire 1 includes a belt layer 7 including at least one belt ply in which belt cords 15 are arranged at an angle of 10 to 40° with respect to a tire equator C. A tread pattern formed on a surface of the tread portion 2 includes a pitch line 22 in which at least two kinds of pattern-constituting units 21 having different pitches in a circumferential direction of the tire are arranged in the circumferential direction of the tire. The belt cords 15 are arranged relatively densely on an inner side of the pattern-constituting unit 21 having a small pitch, and relatively thinly on an inner side of the pattern-constituting unit 21 having a large pitch.
