Verfahren zum Herstellen eines Luftreifens

摘要

A pneumatic tire (1) and a method of manufacturing the tire (1) are disclosed. The tread portion (2) is provided with a bag-like portion (B) filled with a puncture sealant (10). The bag-like portion (B) is formed by interposing an anti-adhesive sheet for preventing adjacent tire materials from bonding each other. The sealant (10) includes a substance which dissolves the anti-adhesive sheet, whereby the bag-like portion (B) is filled with the sealant including the anti-adhesive sheet in solution. The sealant may include water and propylene glycol, and in this case, a water soluble plastics film which is, for example, made of polivinyl alcohol obtained by hydrolyzing polyvinyl acetate is preferably used as the anti-adhesive sheet.
