Volkswagen Golf Service & Repair Manual: Checking tyres
| As tyre damage can have serious consequences, you and the
driver should regularly check the tyres to identify any problems
at an early stage. |
| Damaged tyres cannot withstand driving conditions such as
high speed, long distances, sporty driving, and so on. |
| Damage can be caused in a number of ways: |
| Driving with insufficient tyre pressure |
| Assembly error when tyres were fitted on rims |
| Damage by embedding objects |
WARNING
| Whenever a safety risk cannot be ruled out, the tyre
must be renewed. |

criteria: |

pressure was too low or not sufficient for the load) |

| Separated or deformed bead core |
