Tire Installation Method and Precautions:

1. The rolling direction of the tire is the tire mounting direction(one tire is marked with an arrow, the direction of the arrow is the rolling direction). First, clean the inside and outside of the tires, prevent the presence of gravel and impurities, and attach it according to the rolling direction of the tire.

2. After installation, test whether the bead (tire edge) is uniformly symmetrical and the beads must be all the place outside the beads, and all places must be parallel to the beads. Otherwise, there will be a shake when running.

3. The tube is inserted into the tire with a small amount of air filled (less than 10%) and can not be folded into the tire (folding and inflating the air is easy to puncture), put the tube and tire on the steel ring together, inspect whether the bottom tire is packed into the tire, and do not insert a small step between the tire and the steel ring. Then you can start aerating the tube. This will complete the installation.
