Apologies that I've added unnecessary confusion: yes, it is 66.56mm, not 66.66mm. Precision is important, no doubt, and I wasn't precise. But ... this is not material to the discussion. What is important is that it is 66.6ish, not 66.0, and definitely not 74.1. The 0.1mm difference between 66.56 and 66.66 is immaterial.

By the way, my imprecision was due to the 66.66 spec in reference to Audis or Mercs, IIRC. Great to have standards, huh .

I have 22" inch wheels on my M50i and I'm debating the 20" Style 748M for my winter setup. I'd prefer to have 21" winter wheels and I'm looking for OEM. Does anyone know if the 808M's, part number
36112471521, would fit on the G05?

Not everyone is willing to tell shops how to do their jobs, but they should just pull out their electronic vernier callipers and measure everything to get to root cause without guesses. From the sounds of it, one way or another this rim is not going to fit. It could be the bore, it could be adapter rings, it could be bolt pattern, it could be interference with brake calliper, it could be interference with some other part of the wheel well assembly. After root cause is figured out, you can then blame the right parties and figure out how to fix.

Unfortunately these are the kinds of issues one runs into when not either a) buying stock from BMW or b) getting a turnkey shop to do everything as a single responsibility it makes the vendor 100% responsible for all errors and uncertainties. If it's not a) or b), then you need to do EVERYTHING yourself, including measurements and test fitments before tire mounting it's a pain, but there is no shortcut and luck is unlikely. I've posted before that there are a lot of moving pieces with custom rims.
So I was really interested to find out what the real issue was. You are correct, a tire shop should tell me what the root cause is (and everyone is saying the centre bore size is 66.56, I even measured it myself and it was correct). I took the vehicle today to a second shop, and they said it will not fit, but NOT due to centre bore size, but due to the brake calipers! The first shop said it was the centre hub size, so they clearly did not properly evaluate the fit. It has the M brake package, so I need to find an alternative.

Any recommendations (in Canada)?

Hi,
Selling my Pirelli Scorpion Winter Tires off my 2021 x5
Front: 275/35 r22 purchased from tire rack 2 year warranty
Rear: 315/30 r22 purchased from bmw/1 year warranty

I just bought them less than a month ago and they have less than 1,000 miles on them. Turns out I’m getting rid of my x5 so I’m looking to sell the winter tires.
