A process for producing tyres with auxiliary components for vehicle wheels is described. The process includes i) covering the external surface of an expandable chamber for tyre vulcanisation and moulding apparatuses with a first substantially cross-linkable polysiloxane composition and ii) covering the radially inner surface of the impermeable elastomeric material layer of the green tyre with a second substantially non-cross-linkable polysiloxane composition. An expandable chamber for tyre vulcanisation and moulding apparatuses and, a process for treating the expandable chamber are also described.
