ture . For example, the numbers 2207 mean that the tire was
produced in the 22th week of 2007. The other numbers are
marketing codes that may or may not be used by the tire manufac­
turer. This information is used to contact consumers if a tire defect
requires a recall.
Tire ply composition and materials used
The number of plies indicates the number of layers of rubber-coated
fabric in the tire. In general, the greater the number of plies, the
more weight a tire can support . Tire manufacturers also must indi­
cate the materials in the tire, which include steel, nylon, polyester,
and others .
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
Tire quality grading for treadwear, traction, and
temperature resistance
Tread wear, traction and temperature grades~ page 328.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
Replacing tires or rims on vehicles equipped with tire
pressure monitoring system
The wheels on your vehicle are equipped with a sensor which
constantly monitors the air pressure inside the tire, and then trans­
mits this information to the tire pressure monitoring system. If you
are going to replace the wheel rims on your vehicle, make sure the
new rims also have these sensors . The sensors must be compatible
with the tire pressure monitoring system on your vehicle.
If you install rims, which do not have the sensors, or have sensors
which are not compatible, then the tire pressure monitoring system
will not work properly. In this case, the tire pressure monitoring system would not be able to monitor the
tire pressure or warn you
if it is necessary.
• The battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the valve stem caps securely mounted. We
recommend using factory installed valve stem caps. Ask your autho­
rized Audi dealer to replace lost valve stem caps .
The installation of replacement tires with steel cord body plies in
the tire sidewall may cause malfunction of the tire pressure moni­
toring system, and is not recommended (cord material information
in molded on the tire sidewall).
Always check your tire pressure monitoring system indicator after replacing one or more tires on your vehicle. If the tire pressure
monitoring system indicator flashes, or is on, your system is not
working properly. Your replacement tire might be incompatible with
your tire pressure monitoring system, or some component of the
tire pressure monitoring system may be damaged.
& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control, collision
and serious personal injury.
• Always use tires, rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.

Wheel bolts
Wheel bo lts must alw ays be t ig hte ned to the correct
to rq ue .
The design of wheel bo lts is matched to the factory instal led rims. If
d iffere nt rim s are fitted, the corr ect w heel bo lts w it h t he rig ht le ngth
and correctly shaped bolt heads must be used. This ensures that
w he els are fitted securely and that the brake sys tem func tions
correctly.
I n certa in c ircums ta nces, you may not use wheel bo lts from
a
different vehicle -even if it is the same model=> page 368.
& WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control , a collision and serious personal injury .
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened.
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque .
• Only use wheel bolts that belong to the rim being installed .
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss.
If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving . If the tightening torque is too high, the wheel
bolts and threads can be damaged and the wheel can become
loose .
0 Note
The specified torque for the wheel bolts is 9 0 ft lb (120 Nm) with a
to lera nce of± 7,4 ft lb(± 10 Nm). Torque whee l b o lt s d ia go nally.
Af ter changing a wheel, the torque must be checked as soon as .,_

hub. Remove all dirt from these surfaces before remounting the
wheel. •
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
with their tread pattern pointed in the right direction.
Using a spare tire with a tread pattern intended for use
in a specific direction
When using a spare tire with a tread pattern intended for use in a
specific direction, please note the following:
• The direction of rotation is marked by an arrow on the side of the
tire .
• If the spare tire has to be installed in the incorrect direction, use
the spare tire only temporarily since the tire will not be able to
achieve its optimum performance characteristics with regard to
aquaplaning, noise and wear.
• We recommend that you pay particular attention to this fact
during wet weather and that you adjust your speed to match road
conditions.
• Replace the flat tire with a new one and have it installed on your
vehicle as soon as possible to restore the handling advantages of a
unidirectional tire. •
Notes on wheel changing
Please read the information~ page 325, "New tires and replacing
tires and wheels " if you are going to use a spare tire which is
different from the tires on your vehicle.
After you change a tire:
• Check the tire pressure on the spare immediately after installa­
tion . •
Have the wheel bolt tightening torque checked with a torque
wrench as soon as possible by your authorized Audi dealer or a qualified service station .
• With steel and alloy wheel rims, the wheel bolts are correctly
tightened at a torque of 90 ft lb (120 Nml.
• If you notice that the wheel bolts are corroded and difficult to
turn while changing a tire, they should be replaced before you check
the tightening torque.
• Replace the flat tire with a new one and have it installed on your
vehicle as soon as possible. Remount the wheel cover.
Until then, drive with extra care and at reduced speeds .
& WARNING
• If you are going to equip your vehicle with tires or rims which
differ from those which were factory installed, then be sure to read
the information
~ page 325, "New tires and replacing tires and
wheels".
• Always make sure the damaged wheel or even a flat tire and
the jack and tool kit are properly secured in the luggage compart­ ment and are not loose in the passenger compartment.
• In an accident or sudden maneuver they could fly forward,
injuring anyone in the vehicle .
• Always store damaged wheel, jack and tools securely in the
luggage compartment . Otherwise, in an accident or sudden
maneuver they could fly forward, causing injury to passengers in
the vehicle .
0 Note
Do not use commercially available tire sealants. Otherwise, the elec­
trical components of the tire pressure monitoring system* will no
longe r work properly and the sensor for the tire pressure moni­
toring system will have to be replaced by a qualified workshop. •
