<p><P>PROBLEM TO BE SOLVED: To provide a tire making reducing of noise outside a vehicle such as passing noise due to gas column resonant sound and reducing of noise inside the vehicle such as a road noise compatible at a high level, by using a resonator contacting a road surface to have an air chamber part forming a fixed space. <P>SOLUTION: The pneumatic tire 10 includes a rib-shaped land part 110 provided with a plurality of first resonators; and a rib-shaped land part 210 positioned on the inner side from the rib-shaped land part 110 when installed to a vehicle, and provided with a plurality of second resonators. The first resonator and second resonator include air chamber parts recessed toward the inside in the tire diametrical direction, and a narrowing groove part communicating with the air chamber parts and a circumferential groove. The capacity of the air chamber part of the first resonator is larger than the capacity of the air chamber part of the second resonator. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
