Note regarding Czech website reference: I noticed one of the images of the rim shown on this site has a partial Nissan part number on one of the rim spokes. When I enlarged the image, I can see 4GA3B, NISSAN, and J DOT. If I'm not mistaken the full part number would be D0C00-4GA3B, which is the rim that fits on a 2014-2015 Q50, according to Infiniti Parts Deal. >>>

If you can see a part number on the rims you are looking at, like in that grimy image of the used rim on that Czech site, it could help you figure this out. When I looked up the wheel size for a 2015 Q50, I can see that it has a 5 x 114.3 bolt pattern. >>>
https://www.wheel-size.com/size/infiniti/q50/2015/ I can't fathom why the rims from Eastern Europe would be any different than those used elsewhere. I don't like anomalies like this but I do enjoy a good puzzle. Thanks for letting me play.
