Advantage 3 - Safe: Tubeless Ready wheels no risk of air leaking from the rim bed, the cycling stays safe and the journey could be longer than riding bike with common wheels.

Disadvantage: Needs professional maintaince in case of spoke breaking

Note: Tubeless Ready wheels could also be mounted with tubes.
