Ok, new problem. (old problem I thought I'd leave for down the road)

I have looked into the tire situation. I have found one shop that is willing to work on 2 piece wheels. I am not sure if they're in great shape or not but, they hold air, at
least the tubes do. The rubber is another story, dry rot everywhere. I know that I need 8 new tires.

Could anyone suggest a good place to start looking? Is there an aftermarket
for replacement wheels?

Another question for you guys. I am wondering about the sizing for the tires?

20x9 cant be all the info. What were the tire diameters GM used?

Thanks again for all of your shared wisdom.

8x20 or 9x20 is all there is to the old tire sizes. 9x20 is 9" wide and a 20" rim. I would look in wrecking yards for 6 hole Budd tubeless wheels. They are out there, used on a number of trucks. (not just Chevy). You can find them on moving trucks, some busses, etc. I would NOT use the Firestone RH-5 wheels if that is what you have. They are called Widow-makers for a reason and were sketchy 30-40 years ago! I don't think it is even legal for a shop to work on those anymore.
here is a link to tire sizes and inflation (1956 shop manual supplement) http://chevy.oldcarmanualproject.com/shop/1956sctsm/56sctsm1006.html

You are looking for 22.5" x 6.75" wide 6-lug tubeless Budd Wheels. As Mike said they are out there and not that hard to find.

The tubeless tires are always one size larger numerically then the matching 20" tires, so a 8.25 x 20 will be the same width and diameter as a 9.00 x 22.5 tire and a 9.00 x 20 matches up to a 10.00 x 22.5.

The Firestone RH-5's were discontinued decades ago due to them being unsafe and having the capacity to explode apart without warning. They can be ID'ed by the 2" locking band running around the center of the rim, there is no lock ring at the tire bead. If this is what you have DO NOT AIR THEM UP IF THEY ARE FLAT as they force they generate when they blow apart can lift a car off the ground...your head and arm don't stand a chance!

Thanks guys,
The wheels on the truck are 6 lug. They have a strange split ring on the face of them.
Still not sure which ones they are.

I can't seem to post a picture of them from my phone.

I was wrong, nothing new there. The truck doesn't have the rings on the wheels, the trailer does.
I'll post pictures of them. If you guy's can tell if they are "safe" please let me know.

I am getting very excited, hopefully this weekend I'll get her home

The ones you want to avoid are the Type RH-5's

https://www.stovebolt.com/techtips/wheels/images/49_budd_catalog.jpg

It is easy to confuse them at a glance. I like the three piece wheels like the Type AR. I have had a Type RH come apart on me when I hit a pothole. It was on the front axle too, but luckily wasn't going that fast.

Your right rear outer wheel is an RH-5. Use that to compare the rest. It's hard to tell what the front wheels are from a picture because the split faces inward.

Thank you Mike B,

Mike B
So if I understand correctly, I should be able to match the look of the wheel joint (circled) with the remaining 5 and tell if all my wheels are the
Widow Maker's? Did you by any chance see the picture i posted earlier, of the trailer tire? That seems to be a lot different.

P.S. I am really impressed with your trucks. The NAPCO is beautiful.

Your trailer has a 2-piece split ring wheel and they are still serviceable at any truck or ag tire store.

Yes, that raised center bead is the dead give away that the wheels are RH-5's, that's the only wheelmade like that and it's no longer serviceable.

Thanks for the compliment on my trucks...the NAPCO was sold about a year ago to the Museum of Off Road Adventure in Detroit Michigan.
