<p>A tyre (T) is vulcanised by heating the tyre (T) from both an outer forming surface (So) of an outer mould (2) and an inner forming surface (Si) of an inner mould (3). The inner forming surface (Si) is divided into a plurality of inner forming surface portions (Si1,Si1,Si2) in accordance with portions of the tyre (T), and the inner mould (3) is provided with heaters (5U,5L,5M) capable of heating the inner forming surface portions (Si1,Si1,Si2) at different temperatures. Since the tyre is vulcanised while varying the heating temperatures from inside of the tyre in accordance with the portions of the tyre, it is possible to vulcanise each of the portions of the tyre under optimal temperature condition without generating uneven temperature between upper and lower portions, and thus to enhance the performance of the tyre. <IMAGE></p> |
