Loss of air from tyre
Loss of air from tyre
If the customer complains of a loss of air from a tyre, it is essential that you check for embedded foreign bodies.
  Note
No repair should be attempted on steel-belted tyres if their structure has been punctured by a foreign body.
Corrosion can develop on the steel wires. This will always lead to the separation of the rubber from the steel belt.
Generally, one cannot determine when the foreign body was embedded. The tyre structure may already have been damaged as a result of driving with insufficient tyre pressure.
Damaged belt wires will sooner or later lead to separation of the rubber from the steel belt. As a result, at some point, the tyre can fail completely, long after the tyre was first damaged.
   
Tyre damage caused by foreign bodies is not covered by the warranty.
