'I'he majority of vehicle wheels of today are
equipped with ornamental trim members includ
ing a trim ring or annulus which is substantially
permanently attached to the wheel, These trim
rings are usually formed with a highly polished
exterior surface and for that reason relatively
expensive metal is necessary in their manufac
ture. In order to reduce manufacturing costs
to a minimum, it is desirable to manufacture
these trim rings from extremely thin metal stock.
The thickness dimension or `gauge of the stock
employed is governed to a large extent by the
nature and character of the attaching means

The novel features which I believe to be char
acteristic of my invention are set forth with par
ing (not shown). The circumferentially spaced
portions of the flange I8 are depressed radially
inwardly as at 22 to permit circulation of air
through the wheel. The rear edges 23 of the de
pressed pertion 22 are cut back as is clearly shown
in Figure 2 of the drawings.

The trim ring II of Figure 5 is mounted on the

in connection with Figures 1 to 4.
In connection with the description of the
mounting of the trim ring I I of Figure 5 as well
as of the mounting of the trim ring I l of Figures
