Warm tips for installing tires and tubes:

1. The rolling direction of a tire is the mounting direction of the tire (some tires are marked with an arrow, and the direction of the arrow is the rolling direction of the tire).Clean the inside and outside of the tire to prevent the presence of foreign substances such as gravel and impurities, and install it according to the rolling direction of the tire.

2. After installation, inspect whether the bead (tire edge) is uniformly symmetrical, the bead must be outside the bead in all places and parallel to the bead in all places.Otherwise, there will be blurring when driving.

3. The tube should be evenly inserted into the tire with a small amount of air filling (less than 10%), the carcass should be stacked in order and not folded inside the tire (folding and inflating it is easy to puncture), the tube and tire should be put together on the steel ring, and inspect whether the lower tire is all packed into the tire, and there should be no small steps between the tire and the steel ring.You can then start aerating the tube.Installation is complete.
