If I remember correct, OE wheels' logo is an "O" immediatly next to an "E". i didn't see any logo that looks familiar on your pics.

Do you know the offset? if not, can you measure the backspace? that's the distance from the flat mounting portion of the wheel center measured to the inside of the rim (closest to the differential).

 

I measured 7 1/2 inches, measuring the way you said to.

 

Just an update. I found out they are AFS wheels.
