Pneumatic tire, process for producing the same

摘要

Disclosed is a pneumatic tire (1), which exhibits excellent puncture-preventing function while avoiding inconvenience aroused when a sealant layer is formed based on decomposition reaction of polyisobutylene, and a process for producing the same. This pneumatic tire is provided with an adhesive sealant layer (8), which is disposed in a region of an inner surface of the tire (1), which corresponds at least to a tread. The sealant layer (8) is made of an adhesive sealant obtained by heating a rubber composition containing 0.2 to 20 parts by weight of peroxide per 100 parts by weight of a rubber ingredient containing not less than 50 wt.% of polyisobutylene and a thermoplastic resin film (10) is disposed on at least one side of the sealant layer.
