Abstract
A first stage radial ply carcass and an endless breaker belt are built conventionally about horizontal axes. Carcass and belt separately are upended, to axis-vertical positions. The respective mid-circumferential planes of the carcass and the belt are made coplanar and coincident about the vertical axis of a shaping and curing core, without fixed reference to the vertical axis. The core is raised, into and through the carcass and expanded, first to support the carcass without significant radial deformation due to gravity, and then to expand the carcass to adhere the belt therearound. The assembly of core and belted carcass is then returned to horizontal orientation to receive tread therearound. The tire is cured conventionally while the shaping core remains in the tire, still inflated, preferably with an inert gas.
