Precautions for inner tube use 1. Before installation, clean the inner side of the outer tire first to avoid the sharp sand and gravel remaining in the outer tire from piercing the inner tube. 2. The unevenness of the new inner tube after inflating is a normal phenomenon, because the rubber of the inner tube is different in thickness, and the air nozzle will be thicker. When the pressure is the same, the size of the expansion is also different. The following can be used normally, and it is not a quality problem. 3. Inner tube damage caused by improper installation, non-quality problems such as air leakage after use, cannot be returned or replaced. 4.
