Well, get out your scale, get the diameter of the bolt pattern, bolt patterns are typically stated 6 on (diameter in inches) 9. Probably Motor Wheel, look for large captive washer under nut as was stated. GMC used this wheel.

Coleman vehicles were built in Littleton, CO since the ‘30’s at least, don’t know if all HD ones were built there?
