Volkswagen Golf Service & Repair Manual: Damage caused by foreign bodies

Driving over hard, pointed objects like nails, screws and the like can pierce the tyre.
This always leads to tyre damage.
   
Damage due to embedded foreign body
Often, the object -marking- is so securely embedded in the tyre that it will not free itself even at higher speeds. Consequently, it can act as a plug and seal the tyre relatively well. This results in a gradual loss of pressure, which the driver will not notice immediately, but which can lead to sudden and complete tyre failure.
  Note
No repair should be attempted on a steel-belted tyre of which the structure has been punctured by a foreign body.
