How to install tires and precautions: 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). First, clean the inside and outside of the tire to prevent the presence of foreign substances such as gravel and impurities, and then install the tire according to its rolling direction. 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. Insert the tube evenly into the tire with a small amount of air filling (less than 10%), stack the carcass in order and do not fold it inside the tire (folding and inflating it is easy to puncture), the tube and tire together over the steel ring, and check whether the lower tire is completely 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. The installation is now complete.
