I recreated some classic (JDM-)wheels. 

They're approximately 1:3 scale and have an diameter of around 13.5cm and a width of around 9cm. 

They're not a perfect copy as I drew them just after some pictures from the internet. 

Print them as you like, but I suggest to use "Archimedean chords" as the infill for the top layer, especially on wheels with silver faces. 

The inner and outer lip should be printed with the flange down and print quite good without supports.

I'll do more designs soon, and I'm open for wheel suggestions.
