The resin seems to be strong enough to hold up and when I try to move it side to side it is not floppy. What I did is cast the 2 Indy wheels with the spoked wheel.I cut them in half shaved the middel and have them together. That cut out about 3/32 out of the middel to make the tire skinnier.
I think it looks alot better.
Here is the stock wheel with spoked rim.

Here is the cast wheels shaved and put together. White just does not come out. I will give it a shot of gray so you can see it.

The 2 side by side for comparison.


I think this is the way to go. So it will be 2 halves that need to be glued together. I think the shape and profile is were it should be .
Or I could just cast the spoked wheels and you all can glue them on the stock Indy tire.
What do you guys think ?
