All tires have some cracks. Two tubes (in the black wheels) hold air. Spokes are serviceable. Rear hubs are good. Front hubs need minor adjustment. Rims of black wheels have quite a bit of rust. Rim of back pink wheel had no brake pads on it so shows no wear. Rim of front pink wheel has some light rust spots which should clean up well enough. Price of $10 is for all four wheels. If you want just one wheel or two wheels, it is still $10.
