Re: [Chrysler300] 300C hubcap fitting

I'm pondering the same thing and do not have a full answer yet.  My details are a bit different, but wheel cover issues are the same.  My car is a '65 Plymouth Barracuda originally equipped with 13" x 4.5" rims and full disc wheel covers.  A few years ago I located a set of 14" x 5.5" rims from a later model Barracuda Formula S.  I found the same design wheel covers for the bigger wheels and they fit as you describe with a gap between the outer rim of the cover and the wheel, also seeming to be very securely held in place.  I haven't yet determined if the fit is the same as would be if I had wheels from a '65 Formula S.  I haven't yet talked to someone who could positively answer that.  The only comment I've heard is that , as you said, might promote some brake cooling.  That makes sense to me as in my case disc brakes became an option on the Barracuda in '65, though I believe it was a dealer installation only in that year.

Getting close to finishing my resto and fitted the hubcaps to my wheels and found something odd.  Here in Australia, I used Valiant sports rims (see for photo) in the 14x6.5”size for the optional larger Charger tyres - which is pretty rare (plenty at 14x6”).  They were sandblasted and powder coated.


When I fitted the cap I found there was a gap of about 1/8” between the outer edge of the cap and the rim.  After a bit of head scratching, I fitted the cap to a 14x6” rim I had and found the cap fitted flush against the rim.  After more head scratching, I found there is a difference in width between the outside flange and the depression where the cap tangs drop into.  This is the part where the tyre bead seats.  The rims have a JJ profile if that helps.  I have no idea why this part of two virtually identical rims should be different.  They should have just been ½’ wider in the centre.


If it isn’t an issue  - great.  You don’t really notice it unless you look for it and there may be a bonus in the gap will let air out helping the brakes cool. 


The hubcap seems to hold the same but I am a bit concerned the hubcap might be less stable with this gap.  Has anyone else come across this issue before when using alternative rims?
