【Precautions for using inner tubes】

Before installation, clean the inner side of the outer tire to avoid any residual sand or sharp objects piercing the inner tire.

Uneven inflation of a new inner tube is a normal phenomenon, as the rubber of the inner tube varies in thickness and the air nozzle becomes thicker. When subjected to the same pressure, the size of the expansion also varies. After loading, it can be used normally under the wrapping of the outer tube, which is not a quality issue.

2. Replace the inner tube, align the air nozzle with the wheel hub hole
