PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of clearly recognizing low inner pressure abnormality of a tire even by a general occupant on a vehicle without providing a high-cost electric alarming device. SOLUTION: The pneumatic tire is constituted that extremely heterogeneous high frequency shear noise is generated only during turning of a low inner pressure vehicle by a way that holes are formed substantially at equal intervals in a tire shoulder part ranging from an equatorial plane to a tire shoulder part ranging 50% or more of a tire earth width W to 70% or less, the tire shoulder part being situated at least on one side of a tire and earthing during turning of a vehicle at a low internal pressure and not earthing at an ordinary inner pressure during turning of a vehicle.
