TIRE WITH SPLICED MULTILAYERED FILM INNERLINER

摘要

A pneumatic tire having an innerliner comprising a multilayered innerliner film (4) covering at least a portion of the tire carcass's inner surface in a circumferential direction is disclosed. The multilayered innerliner film (4) contains an RFL adhesive coating on both of its sides and comprises from 2 to 7 layers (7A, 7B, 7C). The multilayered innerliner film (4) has a modulus in a range of from 11 to 20 MPa. The modulus of each of the layers (7A, 7B, 7C) of the multilayered innerliner film (4) successively increases from its innermost layer (7C) adjacent to the tire carcass layer (3), through its RFL coating, to and including its outermost layer (7A) by least one MPa. The multilayered innerliner film (4) has its two end portions overlapping each other to form a splice (6) comprising an inner first end portion (4B) adjacent to the tire carcass layer (3) and an outer second end portion (4A) adjacent to the internal air cavity of the pneumatic tire (1).
