PROBLEM TO BE SOLVED: To provide a pneumatic tire which can make a resonator arranged on a tread surface exert the desired function while sufficiently securing drain performance by a main groove and maintaining the degree of freedom on a design of a tread pattern and high land rigidity. SOLUTION: A main groove 1 successively extending in a circumferential direction thereof is provided to a tread surface. A plurality of resonators 3 opening to the main groove 1 and terminating in a land part 2 are provided at intervals in the circumferential direction. Each resonator 3 is constituted of an air chamber 4 open to a land part surface and a constriction groove 5 for communicating between the air chamber 4 and main groove 1. Projections 6 projecting to a groove side and wall side opposed to each other are provided on groove walls 5a, 5b of the constriction groove 5. COPYRIGHT: (C)2009,JPO&INPIT |
