The invention relates to a method for producing a tyre that comprises the following steps: assembling a non-vulcanised tyre, the tyre including a top, a first flange and a first bead, a second flange and a second bead, and a carcass, each bead including a seat; vulcanising the non-vulcanised tyre in a mould having an asymmetrical configuration for obtaining a vulcanised tyre; characterised in that the mould is such that when said tyre is placed in the mould, in its entire median section, the seat of the first bead (34) defining an angle beta1 relative to the rotation axis and the seat of the second bead (54) defining an angle beta2 relative to the rotation axis, the following condition beta1 - beta2 > 3 is respected, where beta1 and beta2 are in degrees, the angles being defined for each bead relative to an axis Ox (respectively Ox') parallel to the rotation axis positively oriented towards the inside of the tyre, and the angles being positive when they extend radially towards the outside.
