My understanding is that it depends on the car and the brake calipers. 19" Gemini wheels are supposed to fit on a Model Y Performance, replacing the 21" stock wheels but the 19" Gemini wheels might not fit on a Model S Plaid, for example (I don't know if it will fit a Plaid or not, that's just an example). If the brake caliper on the S Plaid is too large, the Gemini wheel won't fit over it. I think that's the compatibility issue.
