Help with alloys

[Mickiete]

I got some alloys for my golf, as I was just putting them on I noticed one alloy is slightly different on the inside, iv attached pictures, the smooth flat one is the odd one out, what could I do to sort this? Also the hole is abit bigger.

The center hole is a bigger? That's for the hub you might need hub rings.

If one wheel has a larger centre bore and the reverse side of mounting face is different on that one wheel, that suggests it’s not a genuine OEM VW alloy but a replica in the style of the genuine article.

The genuine VW alloys will have various distinguishing marks cast into the rear side of the spokes - e.g. part number, manufacturer name, wheel size and offset, VW logo. The ‘odd’ wheel is unlikely to have these distinguishing marks; assuming it doesn’t, then that would confirm to me that it’s not a genuine VW alloy.
