This invention relates to an improved wheel
structure and is directed more particularly to an
improved cover assembly therefor.
One of the important objects of the invention
is to provide, for a wheel cover assembly, a new
and improved retaining arrangement for main
taining the cover assembly upon the wheel struc
ture.
Another object of the invention is to provide,
for a wheel cover, an improved retaining arrange
ment whereby the development of rattle and vi

the tire to give the appearance of a massive tire
upon the wheel structure and to give the appear
