Abstract
A method of manufacture of a pneumatic tire in which an annular component, such as a tread/breaker assembly, is accurately located in a supporting box (30)(15). Other tire components such as sidewalls, and carcass, are assembled to said annular component while it is held in the box. The box (15) (30) is a transfer box which is detachable from a rotatable conveyor (11) for relocation in turn at each of a number of tire building stations (16)(26)(36) to pick a respective component(s) at each station. After picking up the respective component(s) at a station the box (15)(30) returns to the conveyor (11) for movement of the box to the next building station.
