Be careful. The 20" rims are usually two-part or three-part, which can lead to problems mounting tires. My 52 Chevy 2 ton has wheels just like this. They are designed for tube-type tires only. Modern tubeless truck wheels would be 19.5", not 20".
As for tires, you are somewhat limited. Again, I've been going through this on my Chevy. The older 20" truck tires have a much higher aspect ratio than the newer tires. The tires available for the 19.5" wheels tend to be 70 series, which end up in the 32"-33" diameter range.
If these really are 20" wheels, you can get antique truck tires, but expect to pay dearly for them. An 8.25-20 is about the diameter you're looking for. M.E.Miller Tire sells antique truck tires like this.
