Mancini Extra Heavy Duty Rear leaf Springs

Great
I am going to use a set of tires that I have on hand BFG 275/60-15.
I would hope that the extra one inch of arch will give me enough tire clearance?
I had them on a ‘74 Duster with a tremendous amount of room. Like S/S springs. Not as high after they settled down a bit. From my old thread...
The big tire vs. the same size on all 4 corners- 225/75/15 vs. 215/70/14
