If the number is measured @ the bead (like the width), then you'd be adding .500 to the BS for a total of 5.25" which is spot-on for aggressively lowered trucks w/20x8" wheels that need clearance for turning.
SCOTI, all wheels I’ve seen measured, the backspace numbers goes to the actual edge of the wheel.
But I add 1” to the overall with of the wheel when I do the math.
There’s a lot of trucks out there with the wheels really close to the fender lip.
I think they forgot to add the 1”.
