Audi Q3: Tires with Emergency Running Characteristics (PAX), Repairing
General Information
It is generally not necessary to replace a tire after going
flat and after driving on a flat tire.
Note
The affected tire should be removed and checked for damaged
by trained professionals. Assembly work and damage diagnosis on
the affected tire should only be performed by trained personnel.
Proceed as follows to examine a tire with emergency running
characteristics (PAX) after going flat:
- First, the remaining gel must be removed from the tire. The
flat side of the spatula is suitable for this
- Then clean the tire and supporting ring with water and a
cloth to remove the remaining gel residue
- After separating tire and supporting ring, evaluate both of
these components (PAX) according to the criteria described in
the following section
Additional information:
- When remounting, ensure the used supporting ring fits the
tire and rim dimensions
- The rim must be inspected before mounting, as with
conventional wheel/tire systems
- A damaged rim should be replaced
PAX Tires, Examining
Pay special attention to the following criteria when
examining the tire:
- Surface erosion or marbling on the inner side (pressure was
too low or insufficient for the load)
- Detached rubber or loose cords
- Exposed or deformed bead bundle
- Damage to tire bead with visible cords
Supporting Ring, Examining
As with the tire, the supporting ring is generally not
replaced after driving with flat tire.
Replace the support ring if the following damages have
occurred:
- Blowouts or missing parts
- Bubbles and discoloration due to overheating
Repairs on Tires
Note
- Repairs on tires with emergency running characteristics (PAX)
must not be performed with adhesive tape.
- Tire repair sprays must not be used on tires with emergency
running characteristics (PAX) because these products are not
compatible with the gel in the tires.
