During inspection, it is recommended to inflate the tire to the maximum tire pressure of about 3.0bar, and then soak the tire in the sink for all-round inspection.

If the tire is damaged, Michelin recommends that the tire cannot be repaired under the following conditions:

1. The sidewall cannot be repaired.

2. The diameter of the hole penetrated by the crown is greater than 6 mm, which cannot be repaired.

3. If the tire bead is damaged or deformed, the tread is deformed, the rubber is corroded by chemicals or the tire is damaged.

4. Other abnormal conditions cannot be repaired. For example, if you can see the traces of air leakage from the tire (such as tire rolling marks, air bubble, etc.). ), it is not worth repairing, because the tire structure may have been damaged and can no longer be used.

In addition, if some damage has made the tire unusable, it is not worth repairing.

Mushroom nail repair (high cost and best effect) and cold patch repair are recommended repair methods.
