Audi Q7: Tires with Emergency Running Characteristics, Seal Inside-Technology

Audi Q7 (4M) 2016-2024 Workshop Manual / Chassis / Wheel and Tire General Information / Run-Flat Tires / Tires with Emergency Running Characteristics, Seal Inside-Technology

  Caution

It is mandatory for run-flat tires to have a tire pressure monitoring system in the vehicle.

Examining and replacing the seal inside tires should only be performed by trained personnel.

  Note

  • The seal inside technology makes it possible to continue driving without losing pressure, even when the tire is damaged due to external effects.
  • When installing seal inside tires no special rims are required. You can install them on the same rims as standard tires or other tires with emergency running characteristics, except for on the rims for PAX tires.
  • It is not recommended that seal inside tires are mixed with standard tires or other tires with emergency running characteristics.
  • Seal inside tires are stored in the same conditions as standard tires or tires with emergency running characteristics.

Seal Inside Tire Function

  Caution

It is mandatory for run-flat tires to have a tire pressure monitoring system in the vehicle.

Inside the tread of the tire is a coat of sealing material. This prevents a loss of pressure when the shell is damaged. Not depending on if the object which damaged the tire is still in the tire.

Step 1:

An object is driven into the tread. The sealant adheres to the object.

The sealant reacts to the damage and closes the hole.

Step 2:

The object is removed from the tread.

The sealant is pulled via the object into the hole, when the object is removed from the tread.

This way the hole is closed by the sealant.

  Caution

The seal inside technology does not guarantee a repair of the tire after damage.

Unlike run flat tires seal inside tires cannot be driven with low air pressure or flat.

Tires with Emergency Running Characteristics, Repairing

General Information

  Caution

Examining damaged tires should only be performed by trained personnel.

  WARNING

  • Run-flat tires must be replaced after they have gone flat.
  • Pay close attention to the installation instructions.

- The wheel must be inspected before mounting, as with conventional wheel/tire systems.

- The wheels should be checked for damage after a flat tire (true running, axial run-out, other damage) because the wheel could be damaged in an emergency by driving through a pothole.

- A damaged wheel should be replaced.

  Note

  • Flat tire sprays may be used on tires with emergency running characteristics (SST).
  • Tires must be replaced after running flat.
  • Observe the manufacturer mounting instructions.
