To make sure everything fit, the chassis was completely assembled before being disassembled for painting.
The photo above shows the Austin Seven wheel and tire. It's in front of the much larger Pocher RR Phantom II wheel. If you look carefully you can see that some clean up of the feed points on Austin Seven tire is still required.

The wheels are constructed from 3D printed rims and hubs and 8 Ga piano wire spokes. Thin wall brass tubes simulate the spoke tighteners.
A 3D printed tire was used to make silicone molds from which the urethane rubber tires were cast. The urethane rubber is Smooth-On's Reoflex 50, tinted dark gray.
