Thinking about it a little more...
10mm the distance between the hole for the brake's bolt and the bottom of the frame (where the "wheel hosting space" starts)
+5mm (minimum) clearance
-----------
Total 15mm
The short reach brakes have a maximum reach of 59mm without exception
Removing what above calculated are remaining 44mm. These 44mm are the space where the wheel (tire and rim) is inside the brake callipers.
Removing 8-10mm more (the rim's surface for the pads), remaining 34-36mm.
So, a short reach brake with maximum reach of 59mm could host a 34-36mm wide tire (or a smaller tire and fender).
Am I wrong?
