1. Remove the wheel and remove the tire. When picking up the tire, it is best to use a bamboo board to pry up one side, and then press the two sides of the tire as far as possible to the middle to gently peel off. Be careful not to break the two edges of the tire.
2. After cleaning up the foreign matter at the breach, use sandpaper in the tire to roughen the area around the breach and apply cold patch glue (you can apply more, but only apply once), wait for 5 minutes to 7 minutes, and then use a large piece of cold patch film to paste it on Just inside the tire. If the vehicle speed is high, it can be cold patched into double layers to increase the strength of the patch, and two layers of cold patch film of the same size are glued to the symmetrical position in the tire to keep the wheel balanced.
3. After installing the tire, if it is artificially pumped up, start vigorously, try to quickly inflate and seal both sides of the tire, install the valve needle to the specified air pressure, and then tighten the valve needle. Finally check, if there is no air leakage, it can be installed and used.
