You can have flat-free, worry-free caster wheels, and save money, consider this 8" x 2-1/4" solid urethane caster wheel assembly (without 5/16" bearings) for mobility scooters and power chairs. This 8" x 2" caster wheel with 2-1/2" hub sports a solid urethane tire making it an economical replacement. The caster uses two 5/16 1605-RS bearings but these are not included. You can reuse your old bearings or order a new set of two.
This caster wheel assembly comes with the 2-part hub to make tire replacement so much easier.
