Abstract
A green pneumatic tyre is built on a rigid toroidal support externally having a forming surface of a conformation corresponding to the inner shape of a tyre. The green tyre engaged on the expandable toroidal support is introduced into a vulcanisation mould and submitted to a vulcanisation cycle. During vulcanisation, axial moving apart of side portions of the toroidal support is caused so as to press the beads and sidewalls of the tyre against the vulcanisation mould.
