ABSTRACT:
A vehicle wheel rim includes a pair of spaced-apart tire bead seats, axially outwards of each bead seat a tire retaining flange, and axially inwards but immediately adjacent thereto a circumferentially extending tire toe engaging groove. The groove is subdivided in the circumferential direction by at least three bridge members each of which is short in the circumferential direction and traverses the groove to provide a bridge surface substantially at the top of the groove such that the bridge surface may support a normal tire bead when used on the wheel or alternatively a tire with a bead retention toe may engage the toe in the groove to provide bead retention in use.
Preferably four to eight bridge members are provided.
The resultant wheel safely carries a normal tire or a TD type of tire with a projecting, bead retaining toe.
