Abstract: Road equipment wheels often have accessories mounted on or in the cavity formed by the tire mounting rim and the hub engaging face. Mounting systems for these accessories tend to be complicated and difficult to mount to and remove completely from the wheel. The disclosed mounting assembly includes radially movable arms and hand operated centrally mounted bolt or shaft to bring the arms into gripping engagement with the wheel, preferably on the inwardly facing surface of the rim between the inset face of the wheel and a circumferential boss on the rim or on the radially inwardly facing edges of a series of cutout handholds on the inset face of the wheel. The assembly, together with the accesory, can be mounted and dismounted quickly and easily by operation from outside the wheel.
