ABSTRACT:
Disclosed is a low noise pneumatic tire in which a plurality of noise absorbing members of a porous material are attached to the tire inner peripheral surface with intervals in the tire circumferential direction. The number of the noise absorbing members is from 5 to 50. The total length obtained by integrating the lengths of the noise absorbing members in the tire circumferential direction is not less than 75% of the tire maximum inner peripheral length. The distance between each adjacent two of the noise absorbing members is equal to or more than the maximum thickness of the noise absorbing members at the end portions thereof in the tire circumferential direction, while being not more than 15% of the tire maximum inner peripheral length.
