To provide a pneumatic tire for improving maneuvering stability performance in a small steering angle.
This pneumatic tire of designating the direction to the inside-outside of a vehicle when installed in the vehicle, has a plurality of tire peripheral directional grooves extending in the tire peripheral direction of a tread part and a first land part forming a division by the tire peripheral directional grooves, including a tire equatorial surface and continuously extending in the tire peripheral direction. In the pneumatic tire, the length SWHout of a perpendicular lowered to a tire rotary shaft from a tire maximum width position of an area being the vehicle outside when installed in the vehicle with the tire equatorial surface as a boundary in a cross section in the tire width direction of the tire, exceeds the length SWHin of a perpendicular lowered to the rotary shaft from the tire maximum width position of an area being the vehicle inside when installed in the vehicle. Such a tire has a second land part continuously extending in the tire peripheral direction, by forming the division by the tire peripheral directional grooves on the outside in the tire width direction of the first land part in the tread part of the area being the vehicle inside when installed in the vehicle.
