I need some diameter sizes for the old style Skymaster F-18C wheels (Not the new inflatable kind).

Nose diameter"?
Main diameter"?

Hi Chris.
I think the mains are 76mm. I can measure both of mine later and let you know.

Nose wheels 57mm.

It is that AirPower produced.

Nose diameter is 2-1/4" 57mm

Main diameter is 3-1/4" 83mm
