They came on a Camaro and seller said they came off a berlinetta. They are 15's

 

That is called a wheel. Looks to have a rubber tire mounted on it.

 

Ok! I missed that part

 

They don't look like any wheel I've seen, certainly not off a Berlinetta. -at least not originally.

 

Thank you mod. I have not seen any either. That is why I was asking. The lug holes line up like they are supposed to. They were put on to replace the set of 91 z28 type that were on it. The single line 16in iroc wheels were long gone
