I previously replaced the rubber on my spare tire: https://16908.info/?p=1136
The tire wasn’t holding air, and the tire was loose at the bead. I brought it back to Discount Tire, and they re-sealed it with bead sealer. They even did it for free!
I then cleaned the rim with Simple Green, roughed it up with some steel wool, vacuumed it, and cleaned it with rubbing alcohol:
Then I prepped it with two light coats of Bulldog Adhesion Promoter, and painted it with Rustoleum High Performance Wheel Paint:
Finally, tire gloss:
I checked the tire pressure. 60psi. Ready to go, but hopefully it stays in the trunk.
