I have no idea. I just measured but I'm not sure I measured properly.
I took a ruler and put it on the outer edge of the back part of the rim and then measured the distance to the hub. It came up with 13cm. Does that make the offset +13?
Anyway, the backside of the says Mullin wheels, Made in Australia and 16x7.
They came off an E39.
Hope that helps.
