Take the frame to tire measurements off the steel wheel.
(This only works on a frame with parallel rails...)
Measure the "in front\behind the axle" frame width to see.
What I come up with as a fixed point on the farme is the spring bolts, so took that point to the inner bead. This is what I come up doing that, used the inner most face. I was having trouble with the two rear bead measurements, could had got that one wrong but came up with close to the same thing twice.
