Beschreibung
Zusammenfassung:	PURPOSE:To prevent a mold release agent from intruding into the joint part of an inner liner layer at the time of vulcanization in order to avoid its cracking by a method wherein a joint is made between the ends of the inner liner layer at the circumferential ends of a tire before vulcanization and an ultra-high- molecular polyethylene film is bonded to the inner surface of the tire at this joint for vulcanization. CONSTITUTION:A tread 4 has two belt layers 5 provided on the upper surface of a carcass layer 2 and the carcass layer 2 is mounted by being bent over e bead core 1 at each end and has an inner liner layer 3 bonded to the inside thereof. A joint is made by lapping one end of the inner liner layer 3 over the other end thereof at the circumferential ends of a tire end an ultra-high- molecular polyethylene film F is bonded to the inner surface of the tire at this lap joint. A mold release agent is then coated entirely over the inside of this inner liner layer 3, after which it is vulcanized and shared using a metal die. This method can prevent the mold release agent from intruding into the lap joint of the inner liner layer 3 at the time of its application.
