I did this rim 3d model design for my personal purpose while modeling the Audi Q8 RS. So, I thought maybe it would be useful for one of Your projects and will save you some time. I also added grey metal paint as a separate object for those, who don't want to mess with textures, thus You can just simply assign a material.
