ABSTRACT:
A pneumatic tire is disclosed, which comprises a carcass composed of at least one ply and an inner liner arranged inside the carcass and composed of plural rubber layers. In the tire of this type, the inner liner comprises at least three layers of an outermost layer adjacent to the carcass, an innermost layer facing the inner space of the tire and an intermediate layer interposed between the innermost and outermost layers. The innermost layer is composed of a rubber composition containing 15-60 parts by weight of natural rubber and the balance of a halogenated butyl polymer as a rubber component, while the intermediate layer is composed of a rubber composition containing only a halogenated butyl polymer as a rubber component, which is different from that of the outermost layer in the rubber component.
