These wheels fit 2 mm diameter output shafts such as the ones on our tiny  (26:1 Gearmotor). The tire is not removable.

Due to small variances in the sub-micro plastic gearmotor’s output shaft, in some instances, the 14 mm wheel might fit loosely. If you experience a loose fit, you could try swapping wheels or using a small dab of glue to help hold the wheel on.
