PROBLEM TO BE SOLVED: To provide a pneumatic tire with high uneven wear resistance capable of suppressing shoulder drop abrasion and other uneven wear. SOLUTION: On a fourth land part 26 arranged at an inner side of the vehicle at attachment of the vehicle, a plurality of recessions 48 are arranged on an outer portion in the tire width direction along a tire circumferential direction, thereby, rigidity of the land part at a ground-contact end side of the fourth land part 26 is lowered, and shoulder stop abrasion is suppressed. Further, since the recession 48 is made to the state that wear is easily promoted by making rigidity at the tire equator surface CL side higher than the other portion by setting an inclination angleθof the side wall 48A at the tire equator surface CL side larger than an inclination angleθof the other side wall, a projection-like portion becoming a nucleus of new uneven wear can be suppressed from being generated at the tire equator surface CL side of the recession 48, thereby, generation of new uneven wear can be suppressed.
