This vulcanisation mould (1) for tyre (14) mfr. has 600-3,000 air release holes (2). Each has a valve (3) so configured, that it is closed by the approaching tyre blank surface, to re-open again after vulcanisation, during tyre extraction. Pref. in each of the air release holes (2) is a valve (3)with moving insert (4), comprising valve rod (5) with an attached plate (6). The plate presents a frustrated conical section (7) towards the insert internal cavity. On the tyre surface side there is a plane surface (8). The conical surface mates with a valve seat surface (9) in the valve casing or in the surface of the mould (1) segment (10).
