8" wheels

I have a pair of 8" red wheels (8 x 1.75-F) that have been sitting on a shelf for a good many years, but now they are on the go list. They have a metal centre with bearings for a 1/2" shaft. Selling the pair for $20.00. I also have the same size wheels that are white with a steel bushing centre that I am selling for $15.00 for the pair.
