A long time ago I saw an image of the Lotus F-1 in Autoweek when it was published on newsprint... The team using these wheel replacements, all metal, a hoop of steel as the rim/ tire, dished to place the outside edge at the centerline of the actual rubber tire...
For alignment and suspension configuration...
Made me think about bikes... So, mounted true, dished wheels without tires on my bike and while in the stand took a straight 1x2" hollow extrusion and aligned it against both rims as close to center as I could go without spoke interference, made the dropout adjustments from that.
I was pretty close but the bike rode "no hands" easier after that session.
