Thanks for the tires guys!!!!

The ones from Ken would do good for the track, and the ones from Mike M
would be good for the sand!!!

If you haven't seen the ones from Mike, they are killer (pun intended)!

I remember some movie around 10+ years ago with trucks and cars that had
tires that were probably like that (as well as other weapons too!)

All I can say is if one of those blow out, watch out!!!

Thanks a lot for the comments on the buggy modeling!  I sat down with a
peice of graph paper and used my drafting skills from college, and built
them based on some pics I found on the net.

I also know bout them tires, and by the time I got this pic to where it is,
I decided to let them go.  The buggies are eventually going on a race track
that I plan to animate.

  It was intended as a fun exersize in what can be done to a torus
to make it more tire like in appearance.  I was quite pleased with
the grooved tire version. I now need to work on a mehtod of adding
angles to the groove and variations in the cut of the tire. Still need
to add the GoodYear tire logos as well.

I get the feeling from this exercise that detail is everything!  Not to put
that down in anyway!

Hopefully this weekend (and it will be a busy one), I can get more work done
on the track and get the animated stuff rolling.

I would say that with the detail you put into making the frame and body
the few extra steps to make the tires look realistic would be worth the
effort expended.

Actually you are correct!

At the time I did not know how I wanted to make them look.  And I didn't
really know how to go about doing it with _ease_.
