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.

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-
tor ing 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.

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.
•
Only the wheel/tire sizes specified by the manufacturer may be
used on vehicles with all-wheel drive.
•
Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly.
•
Overloading tires cause heat build-up, sudden tire failure,
including a blowout and sudden deflation and loss of control.
