A tyre (1) having : two beads (3); a toroidal body ply (2) wound about the two beads (3) to form two turn-ups ( 4 ); and two bead fillers (8), each contacting a bead (3) and at least partly enclosed inside a turn-up (4) of the body ply (2); each bead filler (8) having a first elastomer ring (9), which is initially placed, flat, between the body ply (2) and a bead (3), is turned up about the bead (3), when forming the corresponding turn-up (4) of the body ply (2), to bring two opposite ends (10, 11) of the first elastomer ring (9) into close proximity, and is ultimately cured, after being turned up about the bead (3), to connect the two opposite ends (10, 11) of the first elastomer ring (9), while at the same time eliminating the air trapped inside the turn-up (4) of the body ply (2). |
