A tire in which the beads have a slip layer over part of their surface to make them slip more readily over the seats of the wheel rim upon removal after use and thus reduce the risk of damage.

Tire with beads designed to ease removal from rim

The carcass cords extend into the bead where they are anchored with at least one pile of circumferentially oriented cords by a rubber mix having a Shore A hardness of more than 70 interposed between the carcass cords and the circumferentially oriented cords. The carcass may be formed from a single cord which passes forward and back from one bead to the other or by cut cords. In some embodiments, the carcass cords are divided in the bead into two circumferential alignments spaced axially apart.
