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.
