PROBLEM TO BE SOLVED: To provide a pneumatic tire ensuring the effective improvement of draining performance, improving flexibility on the design of a tread pattern by sharing a plurality of resonators to a plurality of main grooves, and effectively reducing air column resonance by making the plurality of the resonators having different resonance frequency simultaneously function to each main groove. SOLUTION: On a tread 1, four main grooves 2, 3 continuously extending in a circumferential direction are provided. A lateral groove 4 opening to the two main grooves 2, 3 adjacent to each other is provided. The plurality of the resonators 5a, 5b, 6a, 6b, 6c with different resonance frequency, opening to the main grooves 2, 3 at one end, terminating in a land part at the other end, and being independent from another main groove and lateral groove are provided.
