A green tyre has a symmetric profile in radial section having a radially outer tread band, two radially inner beads and two sidewalls each extended from one edge of the tread band to one of the beads. During a moulding and vulcanisation treatment of the green tyre, a movement is imposed to the tread band with respect to the beads along a direction parallel to a rotation axis of the tyre, to obtain a moulded and vulcanised tyre having an asymmetric profile in radial section. A mould for vulcanizing tyres for vehicle wheels is also described, having a tread wall axially asymmetric with respect to a middle line plane of the mould. |
