Abstract:
A pneumatic tire which uses, as an inner liner layer, a laminated sheet obtained by laminating an air permeation preventing layer, made of any one of a thermoplastic resin and a thermoplastic elastomer composition containing a blend of the thermoplastic resin and an elastomer, and a tie rubber layer, and which has high durability to prevent development of a crack in the tie rubber layer that occurs around a splice portion of the laminated sheet after the tire starts to be used. In the pneumatic tire, a sagged portion is formed by a concavo-convex structure in the air permeation preventing layer at least between points P and Q in a shape that a length La of a straight line connecting points P and Q and a length Lb of the air permeation preventing layer actually passing through points P and Q satisfy a relationship of (1.03×La)≦Lb≦(1.5×La).
