How to fix a bead leak? The NIU KQi3 Pro front tire has a leak around the bead. The bead is the edge of a tire that sits on the wheel, this problem only occurs when you have a tubeless tire.

To fix the leak, you must take out the tire and clean the bead, unless your wheel is damaged, cleaning the wheel and the tire should solve this problem.

Slime is a tire sealant and works instantly and seals punctures.

Do not put slime into the valve to seal the bead, it won't work. (Putting slime inside the tire would only prevent/seal punctures)

Put slime around the bead on the tire and pump it up to 50 psi (or recommended tire pressure).
