ABSTRACT:
A wheel cover which automatically maintains a balancing force applied to the wheel as the wheel rolls along a surface includes a rim for mounting the wheel cover to the wheel and a number of radially inwardly extending spokes. A plurality of weights, each secured to the inner ends of an associated group of spokes, forms a circle of separately movable weights centered about the axis of the wheel. A pair of axially spaced caps capture the weights in a manner permitting the weights and their related groups of spokes to pivot toward and away from the wheel causing the weights to move between radially advanced and retracted positions with respect to the axis of rotation so as to balance the wheel. A second embodiment employs a pair of "dished" annular bodies sandwiching a number of segments therebetween and mounted to move portions thereof with respect to the axis of rotation.
