Has anyone successfully used an Audi wheel fitment on the G30? Bolt pattern is the same but centerbore is slightly off. Audi is 66.5 and the G30 shows 66.6

I have recently acquired a 540d xdrive and need a second set of wheels for winter tires. I too thought of Audi and MB rims using same 5x112 bolt pattern and 66.5 center bore. While I don't think that 1/10 the of a millimeter would matter (as this could be enlarged with a light sanding). The real compatibility problem seems to be the wheel bolts used by VW, Audi and MB - they are ball head lug nuts versus conical ones used by BMW. To further complicate matters, BMW use M14 x 1.25 threaded bolts while VW and MB use M14 x 1.5 bolts. Moreover, I can find no source for a ball head lug bolts matching BMW's finer-pitched threads.

I run W222 Mercedes S Class Wheels on my 2020 M550i. These are a set of 19s from my last car with Michelin PSAS3+ , in one size larger, which work great as "winter" wheels here in NJ. ECS Tuning had the lug bolts to make it work. ES#: 3699137
Mfg#: S17F39R12. These were good for the flange thickness of my MB wheels.

Odd you mention ECS Tuning as a source for MB/BMW lug bolts. I happened on them on ECS after claiming I could not find them. Sounds like you have a really nice setup using S Class wheels. Do BMW center caps fit? They have be better made than many of the aftermarket 19's. I am looking for wheels for winter tires on my G30 (as my old F10 wheels don't fit) and always had good luck using OE wheels taken off older vehicles. Winters where I live are no place for show-car wheels and tires. Used ones that have been curbed or covered with baked-on brake dust function just fine on salt-covered winter roads.

Tommyudo, a question about your MB winter wheel set. I assumed that the 66.56 mm center bore on MB rims would present no problem on BMW's 66.6 mm hubs, but I am having second thoughts. I am curious how you handled this issue on your M550i.
