PNEUMATIC TIRE AND MANUFACTURE THEREOF

摘要

PURPOSE:To cut off the outside air with a thin film to give the ozone crack resistance property, while obtain beautiful gloss with the thin film to improve the appearance by laminating thin films made of a super polymeric quantity of polyethylene on the surface of side walls. CONSTITUTION:A pneumatic tire has side walls 1 in both sides of a tread 5, and has bead parts 4 in the ends thereof. In this case, thin films F made of a super polymeric quantity of polyethylene is laminated on the surface of the side walls 1. This tire with air can be manufactured by laminating films made of a super polymeric quantity of polyethylene against a green tire before vulcanization. Namely, only films made of a super polymeric quantity of polyethylene can be adhered by laminating against rubber before vulcanization and vulcanizing for formation.
