The rim has the tire off but is otherwise all set up, ie spoked to a hub. What I did was put the rim next to the wall, with the axle perpendicular to the wall. Then I laid a small straight piece of wood across the top of the rim until it touched the wall. I measured up from the floor to the underside of the piece of wood, and read 568 mm. Then I measured from the outer edge of the rim inward to the bead, about 7 mm. So, bead seat diameter is ~554 mm measured, so that confirms 559 tires will fit. | |
