摘要： A pneumatic tire of which self-seal function can be improved while the increase in weight of the tire is minimized. The pneumatic tire having an adhesive sealant layer in the region corresponding to at least a tread portion on the inner side of the tire, the adhesive sealant layer being constituted from a rubber composition containing a rubber component to be decomposed by peroxide and 0.2 to 20 parts by weight of peroxide per 100 parts by weight of the rubber component, in which fibrillated short fibers with an average length of 100 to 5000 µ m are mixed and scattered.
