Patent attributes
Disclosed is a low noise pneumatic tire having a configuration where, while installation work of a strip-shaped sound absorbent is simple, it is possible to simultaneously reduce cavity resonance and high-frequency noise, and thereby to effectively reduce noise when a vehicle is traveling. In the low noise pneumatic tire of the present invention, the strip-shaped sound absorbent is attached to an annular elastic fixing band, and then is installed onto an inner surface of a tread of the tire taking advantage of the elastic force of the annular elastic fixing band. The strip-shaped sound absorbent is formed of at least two kinds of porous materials whose sound absorption characteristics with respect to frequencies are different from one another.
