old cragars and a 72 swinger
Before you go through a lot of trouble trying to find the correct tire size, these are not 4" bolt cir unless they have been modified. They never made a unilug with the 4" bolt cir.
I had a set of these and if they are unilug, they are 4 1/2" and 4 3/4 unilug so they will not fit the 4" you currently have, they will work after you convert to the big bolt cir though.
they are 15x7 and appear to have both 5x4 and 5x4.5 bolt patterns(unilug i guess).
