The automotive epoxy primer I want to use on my wheel does not list rubber as a substrate. What do I prime it with?

IDK that the wheel is actually rubber, is it?
I would recommend using an adhesion promoter and then put a good automotive paint over the top of that, no primer.
If you do a web search (which you may have done already) you'll find similar advice.

Went ahead and finished the wheel before any
advice came. The wheel is hard rubber.
1. Grooved the cracks down to the wire.
2. Filled with slow cure steel reinforced epoxy
3. Filed with half round file (8").
4. Applied 2 coats of automotive epoxy primer
5. Filled any low spots or voids with Bondo.
6. Sanded Bondo with 220 git paper.
7. Sprayed two coats high build urethane primer
on the repair areas.
8. Sanded with 600#
9. Still had some slight imperfections so two
more coats urethane primer.
10. Sanded with 600#
11. Sprayed two coats 2K urethane to finish.
12. Rubbed with fine compound to give it a lacquer
look of 1940.
And heh, this wheel looks killer original.

One thing I omitted. I used isopropyl alcohol to
clean initially and before spraying each time.
