Patent ID: 8333856

Claim:
A method for manufacturing a tyre, comprising steps of: assembling an unvulcanized tyre, the tyre including a crown, a first sidewall and a first bead, a second sidewall and a second bead, and a carcass reinforcement, each bead including a seat; and vulcanizing the unvulcanized tyre in a mould having an asymmetric configuration in order to obtain a vulcanized tyre, wherein the mould is such that, when the tyre is placed in the mould, in any meridian section, the seat of the first bead has an angle β 1 with a rotation axis A and the seat of the second bead has an angle β 2 with the rotation axis a, such that: β 1 −β 2 3, the angles β 1 and β 2 being expressed in degrees, the angles β 1 and β 2 being defined, for each bead, relative to an axis Ox and Ox′ parallel to the rotation axis A oriented positively towards outside of the tyre, and the angles β 1 and β 2 being positive when extending radially outwards, and wherein, when the tyre is placed in the mould, in any meridian section, the carcass reinforcement has a first point of inflection located at the first sidewall or at the first bead and a second point of inflection located at the second sidewall or at the second bead, and tangents (T 1 , T 2 ) at the points of inflection of the carcass reinforcement make angles α 1 and α 2 with the rotation axis A such that: α 1 −α 2 0.
