Technical 1950s? Help Wheels identification

Hello I just obtained some wheels they are 15x5 on a 5x4.5 bolt pattern. They have three openings around the overall lug nut location. Does anyone know where and from what car these wheels are from and what those three openings are for? I’m assuming for a center cap. Thank you

They look furrin to me. Where did you get them?

 

just a guess looks like implement or farm wagon any markings on the back. I see a place wear weights were though

 

I pulled some like that offf a mid 50s Studbaker
4 1/2 bolt pattern.

 

Those slots were probably for a 'tang' on a clip that went there to hold a larger diameter hubcap (not wheel cover)

 

Stude

 

The dimples around lug holes look different than Stude picture above

 

Here’s another Studebaker version

And another Stude

 

here's another pic of that stude wheel ad on the hamb

notice you get both styles

 

those look pretty close

Awesome thanks for the help guys yea it looks like they are from a stude. Would you guys know from what stude these came from?

 

Starlite and Camander is where mine came from

 

1950s. They probably used the same wheels on most models.

 

Gees, Dodge ain't been blamed for a while..

 

Would any of you guys know what size the center cap is?

 

this listing says 10 inches, but who knows exactly....
