Abstract: A pneumatic tire is described having a designated rotational direction, wherein drainage grooves in a tread portion are positioned on each side of a tire equatorial line extending at an angle in a direction opposite the rotational direction while curving towards an outside in the tire width direction. An inclination angle θ1 to the tire circumferential direction at the terminal center position of the leading side of the drainage grooves is from 0° to 45°, while an inclination angle θ4 to the tire circumferential direction at the terminal center position of the trailing side of the drainage grooves is from 65° to 90°. Land portions defined by a rib section continuously extend along the tire equatorial line and are further defined by a plurality of branched sections continuously extending and branched from the rib section towards the outside in the tire width direction.
