Help me ID these wheels

Put nice solid air in the tire (30 lbs won't hurt the slicks). Take off the trim ring. (I'm assuming you know how to measure backspace. Offset has to be calculated.)
Lay the wheel flat, with a straight edge across the sidewall of the tire
Measure from the edge to the ground, thru the center hole
(Call it ten inches.)
Measure from straight edge to the wheel bead. (Call it one inch)
Double that one inch, subtract it from 10,you get eight. That's overall width, NOT wheel width. Subtract 1/2" for bead width, twice (two beads) you get seven inches, it's a seven inch wheel.

THESE NUMBERS ARE HYPOTHETICAL, to show how to measure a wheel without pulling the tire off. Your job is to measure yourself, we aren't there.
