Abstract

The present invention provides a method for producing a pneumatic tire, wherein on the inner side corresponding to the tire tread in the radial direction of the tire, at least one continuous belt for reducing cavity resonance in the tire cavity is in the form of A noise reducer is provided on an inner surface of a tire, the method comprising the steps of: providing a vulcanized and molded tire; mixing a composition for forming the noise reducer with a foaming agent to produce a liquid composition; passing the tire through A step in which the tire holding and rotating device is rotated in an upright state, and the liquid composition is introduced onto the inner surface of the tire by means for introducing the liquid composition; while the liquid composition is introduced onto the inner surface of the tire, the pneumatic tire and a step in which the relative positional relationship of the introduction tool along the axial direction of the tire is changed, and the liquid composition introduced onto the inner surface of the tire is formed into a gel; and a step in which the gel-forming liquid composition is foamed and dried.

Description

technical field [0001] The present invention relates to a pneumatic tire and a method of manufacturing the pneumatic tire, and more particularly, the present invention relates to a pneumatic tire provided with a noise reducer in the form of a continuous belt for suppressing cavity resonance generated in the tire cavity and its preparation method. Background technique [0002] Resonant vibration in the tire cavity (cavity resonance) is generated by the vibration of the air enclosed in the tire cavity. When the tire is running, the air in the tire cavity is generally excited by the deformation of the tire tread portion and the sidewall portion, and when the air is excited, the air enclosed in the annular cavity acts as an air column. [0003] The sound waves excited in the tire cavity are propagated in the cabin as solid sound, which propagates through the wheels, suspension system and car body, and is felt by the vehicle occupants as an annoying low-frequency noise. [0004...
