Tires, Air Loss

WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2017 Audi SQ5, 2017 Audi Q5, 2016 Audi SQ5, 2016 Audi Q5, and 2015 Audi SQ5. However, it is still accessible from the selected car via links, so may be relevant.

If the customer complains of loss of air from a tire, the tire must absolutely be checked for embedded foreign debris.

NOTE:

No repair should be attempted on steel belted tires of which the 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, it cannot be determined when the foreign debris was embedded. Therefore, the tire structure may already have been damaged due to driving with insufficient tire pressure.

Damaged belt wires will lead to separation of the rubber from the steel belt sooner or later. As a result, the tire can fail completely after a certain running time, long after the tire damage has occurred.

Tire damage caused by foreign debris is not covered by warranty.
