Abstract
A pneumatic tire and a method of manufacturing the tire are disclosed. The tread portion is provided with a bag-like portion filled with a puncture sealant. The bag-like portion is formed by interposing an anti-adhesive sheet for preventing adjacent tire materials from bonding each other. The sealant includes a substance which dissolves the anti-adhesive sheet, whereby the bag-like portion 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.
