Technical Sombrero wheel cover

I have several of these 1953 Cadillac Sombrero type wheel covers - could someone tell me how to attach these to the wheel - I think these are 15 in. measure 15 1/2 across - shown picture of front and back
thanks in advance - Speedy

 

Those usually require the corresponding '53 Cadillac wheel. They are too deep to fit on a regular wheel.

 

THANK YOU I will check this

 

I’ve seen them with trim rings soldered or welded to them so they fit regular wheels. But like stated they need to be a little deeper than normal for the dish.

 

I have been told this in the past was just intrested how work on stock wheel thank you

 

59/54 at least Caddy wheels were pretty deep to get those caps to fit and had the special center with clips that held the cap. bolt pattern is 5 on 5. Pontiac used a similar setup but I don't know if the wheels are the same.
The red wheels are a set that Marty4-0 posted in the cl***ifieds a few years ago are 56 wheels

 

I cut the center out and tack weld 15 in beauty ring to the outer edge and they went right on regular rims

 

thanks this is probably what I will do

 

thanks for the info I have a set of 56 wheels
