Since those are radials the numbering will be different from Steve's good guess. To me they look like 185/70.
The only "560's" that I know of in today's market are the Firestone F560's from Coker, which are 145 R 15 78S radials. The other option for a nominal 24" tall tire that may give improved wear is a Nankang 145R15 77T which is more readily available. I found the guideline of a 6" to 8" drop in diameter rear to front for the right rubber rake. My '33 is 31" rear, 24" front; and the Deuce will be 32" rear, 24" front.
