What are these?
 

I took these rims in on trade for a truck I had and idk what they are
They have American racing center caps but I cant find them through summit or American racing or anything else.
Anybody have any ideas?

What size are they? 15? 16? 17? What bolt pattern do they have? They look a bit like standard Chevy pickup 6 lug wheels but without the size, there's no way to tell.
