Another option for you.
I bought rims and hub caps that I'm very happy with from Jim Carter Truck Parts. They came primered, and I painted them.
I wanted hub caps that would fit the rims, and look as stock as possible. I know they are pre-1954 hub caps, but I like them.

Another member of this site directed me to the Power King ST205/90R 15 Radial tire. Love them.
