product description:
1. Clean the inner side of the tire during installation to avoid any sharp objects remaining in the tire from puncturing the inner tire. Ensure that all the inner tire is put in the tire to pump air. Sharp tools are strictly prohibited during installation.
2. The rubber of the inner tube is different in thickness, and the air nozzle will be thicker. The uneven expansion after inflating is normal. The inner tube can be used normally after installation. It is not a quality problem.
