Title: TYRE HAVING A REDUCED-WEIGHT BEAD REGION
Abstract:
The invention relates to a tyre with a radial carcass reinforcement formed by a single ply of reinforcement elements, the single ply being turned up around a bead core in such a way as to be anchored in each of the beads. According to the invention, the turn-up of the carcass reinforcement ply and the principal portion of the carcass reinforcement ply are the only plies of reinforcement elements having elongation at break lower than 6% present in the sidewall, and any point of the profile of the outer surface "S" of the tyre between points "F" and "E" is at a distance of less than 1 mm from the spline "P" connecting said first and second points "F" and "E".
