Abstract
A tire and wheel rim assembly in which the rim includes adjacent to the bead seat a circumferentially extending groove and the tire bead has a radially and axially inwardly projecting toe, the tip of which is engaged in the groove whereby the toe is flexible perpendicular to its length to allow tire fitting. However the toe is substantially rigid in the direction of its length, and is provided with an abutment means on the axially inward surface of the bead toe to contact the rim upon rotation of the bead to assist in retaining the bead at its seat.
