How do these rims correlate with reality? If I am not mistaken, their irregular asymmetric shape wouldn't allow free swapping of tyres across the four wheel arches of the car body... 
Right you are, they are not symmetric. But this is a concept car, and for me they look better than the one from the "Minority report" movie. Anyway i will provide a couple of RIM sets, including the original one

By the way, i have also reworked the car seats, the driving wheel, the console, the dashboard, the body materials, the foot pedals, the LEXUS text, etc.
The original model i started with, can be found
there.
