I feel like I need (as in the old Arlo Gutherie song) 8x12 glossy photos with circles and arrows and a description on the back.

Start with your math: 1/4" X 2 = 1/2". Because the backspacing is more that 1/2 rim width--hope you accounted for the bead--subtract 1/2" from 52.5" to arrive at a flange-to-flange distance of 52.00"! Your spoke wheel in this case is what was called "laced in" in the old days, so the center of the tires moves in on both sides from the hub flange by 1/4" per side. Simple . . . right?
