PROBLEM TO BE SOLVED: To provide a pneumatic tire including a plurality of blocks partitioned by a plurality of major grooves extending in a tire circumferential direction and a plurality of lug grooves extending in a tire width direction in which drainage performance and uneven wear-resistant performance can be improved while keeping excellent controllability and stability.SOLUTION: A block 40 of a pneumatic tire partitioned by a major groove 10 and a lug groove 30 includes an obtuse angle part 40A and an acute angle part 40B. When an inclination angle of a groove wall of the major groove 10 adjacent to the obtuse angle part 40A to a tread of a tread part 1 is θa and an inclination angle of the groove wall of the major groove 10 adjacent to the acute angle part 40B to the tread of the tread part 1 is θb, the angle θb is to be an acute angle and the angle θa is larger than the angle θb in which an inclination angle of a groove wall of the major groove 10 adjacent to a side connecting the obtuse angle 40A with the acute angle 40B to the tread of the tread part 1 is gradually increased from the acute angle 40B side to the obtuse angle part 40A side.SELECTED DRAWING: Figure 2 |
