The invention relates to a method for manufacturing tyres, comprising manufacturing a first tyre and manufacturing a second tyre of different dimensions, wherein the bead cores (8) are placed with the same distance between bead cores. During a shaping step, when the radial expansion of the central portion of the carcass ply (4) reaches an intervention diameter strictly less than the formation diameter, a triangulation member (10) is placed in contact with the carcass ply (4) in order to modify the orientation of the carcass reinforcements (6) during a next period of shaping, said triangulation member (10) being provided with parallel reinforcements (12) forming a non-zero angle (β) with the circumferential direction and the initial direction of the carcass ply reinforcements, the intervention diameter and/or the triangulation member being different during the manufacture of the first tyre and during the manufacture of the second tyre.
