Technical what year wheels?

so I just bought two new 6.00-16's with new tubes and liners and they are on , what I believe to be dodge wheels. can anyone tell me what years these wheels were used? I believe they are 30's, but I can't find out much on dodge wheels on the internet. I got a 36 IHC C1 and will be doing a traditional style rod next summer. I have 16" solid wheels off an old IHC pickup that I will be using for the build. probably one of these for a spare. thanks

 

Pretty sure the first one with the oval holes is a 1936 Plymouth wheel. Not sure about the other one though.

 

Left is '36 Plymouth car and '36 Dodge pickup. Right is Dodge and I think it's '34.
