Customs Do you cadillac caps take special wheels

I picked up a set of cadillac caps and I was wondering if they take a special steel wheel for them to fit? Thank you.

 

They take a dished wheel.... no raised center in it. Buick had a similar wheel or they might be the same.

 

I'm pretty sure that those are 56 caps and they do only fit on certain Cadillac rims as far as I know.

 

Cadillac rim on the front of this Pontiac. You can see how much deeper it is than the Pontiac rim on the back.

 

The caddy rim has a deep "first step" , you can see it in wvenfields picture. They even have special wheel weights with a longer mounting arm to fit these types of rims.

 

depends on the cap. some yes, some no. generally, in my experience if it's a rim clip probably not, center clip probably. disclaimer I generally only mess with 50-53 sombreros.

 

had a '79 coupe deville and the wheel covers attached with three little clips . those wheels had a lip on the rim, but it threw 'covers with great regularity.

I have caddy caps on crown Vic wheels no problem but they didn't fit on 70c10 wheels

 

Look like 58 caps to me. Only fit Cad rims, others with modifing

 

Like the others said 1956 and will only fit the deep rims. I have cut the centers out of these 56's. The outer part makes a hell of a nice trim ring.
