Tire Size 68 Barracuda

If you read the tire manufacturers' recommendations, the widest tire you can fit on the stock HD 14 x 5.5" wheels is 215 (so, 215/70-14). If you have the standard 14 x 4.5" wheels, it would be 205/70-14.

I am assuming A56 is running 235/60-14 because 235/70 would never fit, and I don't think anyone makes one, anyway. But 235 is technically too wide for the rims.
