Clean the inner surface of the rim without burrs and dirt2. The position of the air nozzle hole about 10 cm starts to wrap the tubeless pad to cover3. Pull harder during the winding process to make the tire pads stick to the inner side of the rim smoothly without air 4.

During installation, try to that the tire lip is in the groove on both sides of the rim, so as to prevent air leakage8. Start to inflate, try to choose a -capacity high-pressure air or pump9. Fill to the appropriate value according to the tire pressure indicated on the tire10.
