To provide a pneumatic tire capable of simultaneously having pattern noise performance, while maintaining at least maneuvering stable performance and hydroplaning performance.
A tread part of the pneumatic tire has a circumferential directional main groove on both sides with a center line as the center. The pitch number of a first side tread part with the center line of the tread part as the center, is the number of 1.2-1.6 times of the pitch number of a second side tread part on the opposite side of the first side. First side rubber hardness of the tread part is higher than second side rubber hardness at 20°C. Out of the circumferential directional main grooves, a groove width of a first circumferential directional main groove positioned on the first side, is 70-95% of a groove width of a second circumferential directional main groove positioned on the second side.
