Pneumatic tire with an innerliner and method of making the same

摘要

A tire comprising a tire tread (14), a tire layer (21) circumferentially disposed radially inwardly of the tire tread (14) and including a first end (21 A) and a second end (21 B) situated adjacent each other to define a butt joint, and a barrier layer (24) circumferentially disposed radially inwardly of the tire tread (14) and situated adjacent the tire layer (21) is disclosed. The barrier layer (24) includes a first end (24A) and a second end (24B). A portion of the first end (24A) of the barrier layer (24) overlaps the second end (24B) by at least 1.5 cm to define a lap joint. The first end (24A) of the barrier layer (24) is received between and extends beyond the butt joint so that the first end (21 A) of the tire layer (21) is sandwiched between the lap joint.
