3DnuTTa's Rim Design Tutorial

Here is a tutorial I have put together on designing wheels, the tutorial is done in Maya 7, but I’ll try and keep techniques as broad as possible so you can follow it in any other 3D applications.

Note: Please note I've not studied car design, so these are just my methods and probably have some faults, so I'm sorry if it's not the best

edit: I have added a new step, all comments welcome
