My rim is a K18 722 IC rim, The 18 is about half the height as the K and the 7. Rim decodes as being built in the Romulus Mich. Kelsey wheel plant on July 22 nd 1968. It has a D70-14 space saver tire on it. It's not correct for my car, but takes up way less space then a fullsize 235/60-R14 spare would. I'll have to look up the IC application code, when I bought it a hundred years ago (OK 1991) I was told it was from a 68 Camaro, but we all know what that info is worth at a swap meet. Don't know what kind of a car would get a D70-14 spare as its not a Camaro standard tire size.
