Your right. Through the dirt and fuzzy picture I didn't see them. Was too excited that I thought I found it. My original thought was Jeep wheels, but didn't find conclusive pictures.
They look like aftermarket wheels from a '50s 4WD conversion. They're too wide to be out of the '40s...
Early 50's late 40's Old's? A buddy of mine has a 31' Chrysler coupe, someone put an early 50's maybe late 40's Old's rearend in it and reversed the rims. They sure look the same as the pics you have?
I just came across this thread. I believe I may have a single wheel that matches. I bought it years ago. It took me some time to track down what it is/was. It may take me a bit to dig that info up to confirm it is the same as yours and the info I found because I had it on an older computer. I believe I saved the file. I will get back to you.
