Claim Text:
1. A pneumatic tire comprising: one of a thermoplastic resin and a thermoplastic elastomer composition containing a blend of the thermoplastic resin and an elastomer for an air permeation preventing layer, such that a concavo-convex structure, including at least one of a concave portion and a convex portion, is formed in the air permeation preventing layer at least between a point P and a point Q in such a shape that a length La of a straight line connecting the point P and the point Q and a length Lb of the air permeation preventing layer actually passing through the point P and the point Q satisfy a relationship of (1.03×La)≦Lb≦(1.5×La), where the point P is a point at which a perpendicular line extending from a cavity-side end A of a splice portion of the air permeation preventing layer to the air permeation preventing layer on a non-cavity side intersects the air permeation preventing layer on the non-cavity side, and the point Q is a point at a position on the air permeation preventing layer away from the cavity-side end A of the splice portion of the air permeation preventing layer by 25 mm in a first direction of a tire circumferential direction toward a position where the air permeation preventing layer on the non-cavity side is exposed.
