Some people asked me how I make the tires of my ninja at http://www.talkgraphics.com/showthread.php?t=37694
I'm uploading a mini tutorial to explain how to achieve it.
First of all I want to thank to Ron Duke who some time ago explained me many things about tires.
It would be a pleassure translate this tutorial to spanish if somebody needs it.
Any question or comment is welcome.
