A tire having two beads, with a toroidal body ply wound about the two beads to form two turn-ups, and two bead fillers, each contacting a bead and are partly enclosed inside a turn-up of the body ply. The bead filler includes a first elastomer ring, which is initially placed flat and between the body ply, and a bead, which is turned up about the bead when forming the corresponding turn-up of the body ply, to bring two opposite ends of the first elastomer ring into close proximity. The bead filler is cured, after being turned up about the bead, to connect the two opposite ends of the first elastomer ring, while at the same time eliminating the air trapped inside the turn-up of the body ply.
