numbers or letters indicate the plant where it was manufactured, and
the last four numbers represent the week and year of manufacture.
For example, the numbers 2209 mean that the tire was produced in
the 22nd week of 2009. The other numbers are marketing codes that
may or may not be used by the tire manufacturer . This information is
used to contact consumers if a tire defect requires a reca ll.
Audi Original tire
Tires with the identification "AO" or "RO" have been specially
matched w ith your Audi. We recommend using only these t ires
because they meet the highest standards regarding safety and
driving characteristics when used correctly . Your autho rized Aud i
dealer will gladly provide you with more information.
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 mater ials in the t ire, which include stee l, nylon , polyester,
and others .
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carr ied by the tire .
Tire quality grading for treadwear, traction, and
temperature resistance

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 wh ich
constantly monitors the air pressure inside the tire, and then trans-
mits this information to the tire pressure monitoring system*.
If you
Safety first
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 t ire pressure monitoring system* on your vehicle.
If you install rims, which do not have the sensors, or have sensors
wh ich are not compatible, then the tire pressure monitoring system*
will not work properly. In this case, the tire pressure monitoring
system* wo uld 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 dr ive w ith the valve stem caps securely mounted. We
recommend using factory installed valve stem caps . Ask your autho -
rized Audi dea ler to replace lost valve stem caps.
The insta llation of replacement tires with steel cord body plies in the
tire sidewall may cause malfunction of the tire pressure monitoring
system*, and is not recommended (co rd 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 moni -
toring system* indicator flashes, or is on, your system is not work ing
properly . Your replacement t ire might be incompatib le with your tire
pressure monitoring system*, or some component of the tire pres-
sure 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 .._
