Stud wheels are easy - you simply measure the distance from the centre-line of
the wheel to the face of the wheel hub that bolts up to the axle hub, which is
usually flat. But what about wire wheels? It is measured to the back of the
wheel hub or at the inner taper? And if at the inner taper is it the wider
edge? The narrower edge? Or between the two?
MGB wheel offset is usually given as '22mm approx', but doesn't it vary with
wheel width in order to keep the wheel centralised in the well? 4", 4.5" and
5" widths were used at various times, my 5" Rostyles measure 26.8mm, and my
4.5" wires 20.45mm (to the middle of the taper). Shouldn't wire wheel offset
be significantly less than steel or alloy? Isn't that why wire wheel axles
are 1.75" (banjo) or 1.5" (Salisbury) narrower than stud axles?
An enquiring mind wants to know.
