    • PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of preventing any degradation of uniformity by smoothly discharging decomposed gas generated from an adhesive sealant layer during the vulcanization. SOLUTION: In the pneumatic tire T, an adhesive sealant layer 5 consisting of a rubber component to be decomposed by peroxide is arranged on the inner side of an inner liner 4 at a tread part 1, and the inner side of the adhesive sealant layer 5 is covered by a rubber layer 6. A sheet piece 7 in which at least one side thereof forms a releasing surface to be peelable from at least one of the adhesive sealant layer 5 and the cover rubber layer 6 is arranged so as to be across an adhesive seal part Q and/or P at an end of the cover rubber layer 6. One end of the sheet piece 7 is inserted between the adhesive sealant layer 5 and the cover rubber layer 6, and the other end is protruded outside the adhesive seal part Q and/or P.
