Method of controlling a phase of moulding an annular fixing structure and a tyre including an annular fixing structure

A tyre comprising:

• a toroidal ring-shaped carcass structure, comprising at least one carcass ply associated with at least one annular fixing structure;
• and
• a tread band positioned radially externally with respect to said carcass structure,
• wherein said annular fixing structure comprises a radially inner and axially inner surface and a radially inner and axially outer surface, the surfaces being substantially opposed to each other, said radially inner and axially inner surface and said radially inner and axially outer surface having been shaped by successive application thereto of:
• a first squeezing pressure produced by using a first surface and a second surface of a curing mould which are brought towards each other;
• and
• a second squeezing pressure produced by using said first and said second surfaces which are brought closer together, and
• wherein said radially inner and axially inner surface and/or said radially inner and axially outer surface have a shape including air evacuation channels.
