ABSTRACT:
A tread strip is positioned in proximity to the outer periphery of a tire carcass. A bonding substance is provided intermediate the carcass and the strip and has adhesive characteristics sufficient to temporarily bond the strip to the carcass when the strip and carcass are pressed together. The bonding substance is also sufficiently plastic to result in intimate contact by the substance of the facing surface of the strip and the carcass when the strip and carcass are pressed together. The bonding substance, for example unvulcanized rubber, is capable of permanently bonding the strip to the carcass when the bonding substance is sufficiently heated. Initially, the strip and carcass are pressed together in such a manner as to expel gases from between the strip and carcass and in such a manner as to cause the bonding substance to temporarily bond the strip to the carcass. The bonding substance is heated to a temperature resulting in permanent bonding of the strip to the carcass, and during the heating step, escape of the bonding substance from between the strip and the carcass is prevented.
