<p>A vehicle wheel rim has a rim base (1) carrying a pair of bead-retaining flanges (2, 4), one of which is on a bead seat ring (5) releasably retained, in use, on the rim base (1) by a locking ring (6) engaging in a groove (7) formed in a gutter section (3) of the rim base. The locking ring is shaped so as to cooperate with formations (5A, 9) respectively in the bead ring (5) and rim base (1) to provide a positive lock limiting relative rotation between the bead seat ring and rim base.</p> |
