Pneumatic tire having resonant noise reducing structure

摘要

To provide a pneumatic tire capable of reducing generation of resonance noise inside a tire.SOLUTION: A pneumatic tire includes a base film (80) mounted on an inner liner (60), and a plurality of porous sound absorption members (100) which are previously mounted on the base film (80) and are arranged at predetermined intervals. Each of the porous sound absorption member (100) has a cross tube having a large number of through holes (130) on a tube wall, and the porous sound absorption member (100) and the base film (80) are composed of resin materials containing polypropylene.SELECTED DRAWING: Figure 2
