Abstract

PURPOSE:To reduce columnar resonance generated in a void consisting of a groove of a tire against the road surface by providing a resonance cell recessed and linked with a siping. CONSTITUTION:A rib pattern tire is constituted by forming main grooves 2 continuing in the circumferential direction on a tread part of a tire and sipings 3 connected to these main grooves 2. At this time, resonance cells 5 are recessed and linked with the sipings 3. In this way, by linking the resonance cells 5 with the sipings 3, it is possible to effectively reduce columnar resonance generated between the road surface and the tire main grooves 2, that is, pattern noise. Consequently, it is possible to acquire the low noise rib tire without spoiling motive performance demanded for a tire.

In the process from the contact of the groove on the tire surface with the road surface to the separation thereof, the air flow out in the groove due to the compression of the volume of the void formed between the road surface and the groove of the tire, and the void due to the recovery of the volume. The main factors are the pressure fluctuation caused by the pumping action in the groove and the inflow of air into the groove, and at the same time, the resonance sound caused by the groove forming an air column tube.
