Quote - I actually wrote a magazine article on how to make this tire.  It only takes about 10 minutes after you get the modeling done. Build the rim. Build the central ring. Build one spoke. Get one spoke setup the way you want it. Regroup that one spoke. This will put a new coordinate system around the spoke which is aligned with the world again. Move that new groups hot point to the center of the wheel. Then duplicate and rotate.

got a copy of the demo somewhere?  :) My problem is I want to do it as a true 3 cross "laced" wheel instead of a radial but when I pitch it out proper when I go to copy/rotate it doesn't go around the hub.. :/
