Abstract: This invention provides a pneumatic tire (T) including: a tacky sealant layer (5) formed of a rubber component decomposable by a peroxide, and disposed on the inner side of an inner liner (4) in a region corresponding to a tread part (1); and a cover rubber layer (6) covering the inner side of the tacky sealant layer (5). A sheet piece (7) is disposed to traverse an adhesive seal part (Q) and/or (P) at an edge portion of the cover rubber layer (6), while at least one surface of the sheet piece (7) is a release face which can be separated from at least one of the tacky sealant layer (5) and the cover rubber layer (6). A first end of the sheet piece (7) is inserted between the tacky sealant layer (5) and the cover rubber layer (6) while a second end thereof protrudes to the outer side of the adhesive seal part (Q) and/or (P).

Abstract: Provided are a pneumatic tire T and a method of manufacturing the same. The pneumatic tire T includes: a tacky sealant layer 5 which is formed of a rubber component thermally decomposable with a peroxide, and which is disposed on the inner wall surface of the tire at least in a region corresponding to a tread portion 1; a cover rubber layer 6 which covers the tacky sealant layer 5. In the pneumatic tire T, the cover rubber layer 6 is provided with at least one gas vent hole 7a (7b) formed therein. This allows decomposition gas generated from the tacky sealant layer 5 to be discharged through the gas vent hole 7a (7b) to the outside of the tire.
