That is an AMC rim....is there a tire on or off the rim ? Not saying it didn't happen, but I've yet to see an F-78-14 space saver tire on a 5 inch rim, E78-14 replaces 7:35-14, yes. E-body F78-14 or 7:75-14 space saver tires were on flat faced 5.5 rim so could be used on a disc brake system if needed.
