What Steelies are these?

I scored some cool wheels for my model A. Steelies with 5-1/2 bolt pattern. Only trouble is I only have three of them. Can anybody tell me what to look for so I can get another one. Does any one have one they want to sell?

 

What diameter are they?

 

looks like a Ford truck wheel maybe 73 and later

 

Looks like inside hubcap "bumps", so probably earlier.

if they are 15" rims they are probably late 40's up to 60's ford truck.

 

1940 - 1948 Ford p***enger and pickup - 16".

1946 - 1948 Mercury car and 1953 - 1956 Ford pickup have the same design in 15".

 

My '52 F1 has stock 16" rims. I checked on Carnut.com,according to their specs, up to '53 all fords had 16' rims, I'm sure someone else will pipe in in the meantime thats it..

 

These are 16"s
