For general information, there are two bumps 3 1/4" apart astride the valve stem hole on each of the 15" X 5.5" standard, stamped steel, wheels on my 1955 C-300. The wheel covers have punched out and raised ears in the proper positions to engage the bumps. I am running wire wheels now, but recall the C-300/Imperial wheel covers squawked a lot while rolling. Close inspection of the wheel covers shows some wear and rounding of the engaging barbs. Has anyone tried sharpening these or prying them out for a tighter fit? The wheel covers were difficult to install, almost requiring two people--one to position the cover and the other to run the rubber mallet. Three more questions: What material keys were originally issued with the 1955 C-300? Aluminum or nickel-plated brass? Has anyone purchased, installed and driven the 8.00X15 General 3" WSW tires from Lucas Automotive? One of these wheel e-mails indicated the new rims were designed for radial tires. Without opening that can of worms, does anyone know the difference between rims designed for radial tires and the pre-radial "safety rim" wheels?
