Volkswagen Touran Service Manual: Foreign Object Damage
| Driving over hard, pointed objects like nails, screws and
the like can pierce the tire. |
| This always leads to tire damage. |

|
| Damage from Imbedded Foreign Bodies |
| Frequently, the foreign object
-marking- is so securely embedded in the tire that it
will not free itself even at higher speeds. Due to this, it can
act as a plug and seal the tire relatively well. The result is
gradual loss of pressure which the driver does not notice
immediately but which can lead to sudden and complete tire
failure. |
 Note
| No repair should be attempted on steel belted tires of which
the structure has been punctured by a foreign body. |

Disintegrated Tread
| Tires with Torn-Out Tread |
| Such damage usually develops over a longer period of time.
If an already damaged tire is exposed to high stress, the
centrifugal force at higher speeds can tear components off the
tire. |
| Illustration shows a tire with torn-out tread due to driving
with insufficient tire pressure. |

A swelling in the flank of the tire indicates that the
substructure of the carcass has been damaged.
