Abstract

A method of building a closed tube-tire includes constructing a green tire carcass (13) on a disintegratable core (17) and curing the tire carcass (13) in a curing mold (10) having two halves (11,12) which are movable between opened and closed positions. The green tire carcass (13) is intentionally constructed undersized so that a space (18) exists between the green tire carcass (13) and the curing mold (10) to prevent the core (17) from being cracked or crushed when the halves are closed around the tire carcass (13).
