<p><P>PROBLEM TO BE SOLVED: To provide a tire compatibly achieving reduction of vehicle outside noise such as passing noise caused by air column pipe resonance sound and reduction of vehicle inside noise such as road noise in a high level using resonators forming a fixed space while being brought into contact with a road surface. <P>SOLUTION: This tire 10 includes a plurality of a rib-like land section 110, a rib-like land section 210 and a rib-like land section 240 divided by a plurality of circumferential grooves 11, 12, 21 and 22 extending in the circumferential direction of the tire, and the resonators recessed inward in the radial direction of the tire, forming a prescribed space by grounding the rib-like land section 110 on the road surface and communicated with the circumferential grooves. Each of the resonators includes a plurality of first resonators provided in the circumferential direction of the tire and a plurality of second resonators located further inward than the first resonators when the tire is mounted in the vehicle and provided in the circumferential direction of the tire. The number of the second resonators is greater than that of the first resonators. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
