I got to the point where I really started to hate the other picture I posted
(Subject: Dune Buggies), so I reworked a couple things.

That is som very good modeling on the buggy bodies. The tires on the
other hand. Ok I know that you know, I just wanted you to know, that
I know you knew.
I have a presnt for you. Those tires were bothering me so much that
I hacked out a couple of possible solutions for you. The small image
pretty much tells it all and the script is short so enjoy.
Please have them installed before you post again.

Now, no disrespect to your tires Ken, but I think for the dune buggies he'd
be looking for some more rugged type tires, whereas yours look more like
something to be used on highways and in cities. Here's about 20 minutes of
fooling around with toruses. Some tweaking is necessary to make them look
just how you want'em, but i think something along these lines (with some
decent texture) would work well.
code attached.

I like all the tires. However... I believe he mentioned a track. So
could be paved, or could be dirt. Either way, how can he lose now?

If you're going to be out in the desert, you want something to give you
more traction on the dunes (and any hostiles you may encounter). :)

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.
