& WARNING (continued)
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• 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
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip

Bead separation means a breakdown of the bond between components in the bead.
Cord
means the strands forming the plies in the tire.
& WARNING (continued)
• 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.
• If you notice unusual vibration or if the vehicle pulls to one side
when driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage . •

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 229 Tire pressure
label: located either on
driver's side B-pillar or
inside the fuel filler flap
Tir e pressure generally refers to the amount of air in a tire that it
needs it to do its job and safely carry the combined load of the entire
vehicle and its contents. T ire pressure is measured in kilopascals
(kPa), the international measuring unit and in pounds per square
inch (PSll. Tire pressure is based in part on the vehicle's design and
load limit -the greatest amount of weight that the vehicle can carry
safely and the tire size . The proper tire pressure is frequently
referred to as the "recommended cold tire inflation pressure." Air in
the tires expands when the tire heats up because of internal friction
when it flexes in use. The tire pressure is higher when the tire has
warmed up than when it is "cold." It is the inflation pressure in a
"cold" tire that counts. Therefore, you should never let air out of a
warm tire to match "cold tire inflation pressure" recommendations.
The tires would then be underinflated and could fail suddenly.

Main taining proper tire pressure is one of the most important
things you can do to help avoid sudden tire failure. Underinflated
tires are a major cause of sudden tire failure. Keeping tires at the
right pressure is also important for safe and responsive vehicle
handling, traction, braking and load carrying.
Tire pressures are
particularly important when the vehicle is being driven at higher
speeds, and then especially when heavily loaded even within the
permissible load-carrying capacities approved for your vehicle.
The recommended tire pressures for your Audi depend on the kind
of tires on your vehicle and the number of passengers and/or
amount of luggage you will be transporting.
On USA vehicles, the tire pressure label is located on the driver's
side B-pillar. On Canada vehicles, the tire pressure label is located
either on the driver's side B-pillar or inside the fuel filler flap . The tire
pressure label lists the recommended cold tire inflation pressures ..,.

T he correct tire pressure for the spare wheel is located on a label
either on the driver's side B -pi llar or inside the fuel filler flap.
Because technical changes may be made to vehicle equipment
during the mode l year, always compare the tire size designation on
the tire pressure label on your vehicle with the tires on your vehicle. Make sure that the tire size information on the vehicle labe l is the
same as the size of the tires on the vehicle. This is especially impor
tant if the vehicle belongs to someone else or you bought the
vehic le with different rims/tires or you bought the vehicle as a previ
ously owned vehicle.
Remember, your safety and that of your passengers a lso depends
on making sure that load l imits are not exceeded. Vehicle load
includes everybody and everything in and on the vehicle . These load
limits are techn ically referred to as the vehicle's Gross Veh icle
Weight Rating ("GVWR"l. The Gross Axle Weight Rating ("GAWR"l is
the maximum load that can be applied at each of the vehicle's two axles. The Gross Vehicle Weight Rating and the Gross Axle Weight
Rating are l is ted on t he safety compliance sticker labe l located
either on the driver's side B-pillar or on the inside of the fuel fi ller
flap. The ti re pressure labe l on your Audi lists the maximum
combined weight of a ll of the occupants and luggage or other cargo

Checking tire pressure
The correct tire pressure for the tires originally installed
on your vehicle is listed on the tire pressure label located
either on driver's side B-pillar or inside the fuel filler flap .
The recommended tire pressures are on the ti re pressure label and
in the table=>
page 291, "Cold tire inflation pressure".This means
that the pressure must be checked and adjusted when the tire has
not been driven for more than a couple of mi les (kilometers) at low
speeds during the previous three hours. Air in the tires expands
when the tire heats up as a result of internal friction as i t flexes in
use. The tire pressure is higher when the tire has warmed up than
when it is "cold ."
It is the inflation pressure in a "cold" tire that counts. Therefore, you
should never let air out of a warm tire to match "Co ld tire inf lation
pressure" recommendations=>
page 291. The tires wou ld then be
underinflated and could fail suddenly. .,_

The tire pressure label on your Audi lists the recommended cold tire
in flation pressures at maximum capacity for the new, origina l equip
ment tires that were on your vehicle at the time it was manufac
tured. For the location of the label
~ page 291, fig. 229 .
Most tires lose air natural ly over time. They can a lso lose some air if
you drive over a pothole or hit a curb while parking. It is usually not
possible to see whether the radial t ires used today are underinflated
just by looking at them.
Therefore, be sure to check tire pressures at least once a month and always before going on a long trip. Make sure to take the number of
people and the amount of luggage into account when adjusting tire
pressure for a trip - even one that you would not consider to be
"long ." See ~
page 295, "Tires and vehicle load limits" for more
important information .
Always use an accurate tire pressure gauge when checking and adjusting inflation pressures. Check a ll of the tires and be sure not
to forget the spare tire . If the pressure in any tire is too high when
the tire is "cold," let air out of the tire s lowly with the edge of the tire
gauge and keep checking the pressure until you reach the pressure
that is correct for the load (passengers and luggage) and kind of
driving you p lan to do.
If the pressure in any tire is too low, note the difference between the
press ure in the cold t ire and the pressure you need and add the air
that you need to reach the correct pressure for the vehicle load
(passengers and luggage) for the tires on your vehicle as listed on
the on your vehicle and in this manual and the kind of driving you p lan to do .
Nev er e xce ed the m aximum i nflation pr essure listed on the tir e
s ide wall for any re aso n .
Reme mber that the veh ic le manufacturer, not the tire manufacturer,
determines the correct tire pressure for the tires on your vehicle .
It is important to check the tire pressure when the tires are cold.
• Read the required tire pressure from the tire pressure label. On
USA vehicles, the tire pressure label is located on the driver's side 8-pillar
. On Canada vehicles , the tire pressure label is located either
on the driver's side B -pi llar or inside the fuel fi ller flap . The ti re pres
sure labe l lists the recommended co ld tire inflation pressures for
the vehicle at its maximum capacity weight and the tires that were
on your vehicle at the time it was manufactured . For recommended
tire p ressu res for normal load conditions, please see chapter
=> page 291.
• Turn the va lve stem cap counte r-clockwise to remove it from the
tire valve.
• Place the air pressure gauge on the valve.
• T he tire pressures should only be checked and adjusted when
the tires are co ld . The s lightly raised pressures of warm tires must
not be reduced .
• Adjust the tire pressure to the load you are carrying.
• Reinstal l the valve stem cap on the valve.
Wh en should I ch ec k th e tir e pr ess ure?
The correct tire pressure is especially important at high speeds. The
pressure should therefore be checked at least once a month and
a lways before starting a journey . Do not forget to check the tire pres
sure for the spare wheel.
When should I adjust the tire p res sure s?
Adjust the tire pressure to the load you are carrying . After changing
a wheel
or replacing whee ls you have to adjust the tire pressu res on
a ll wheels . In addition, you must then initialize the new t ire pres
sures in the tire pressure monitoring system*~

& WARNING (continu ed )
• Incorrect tire pressure and /or under inflation can cause
in creased tire wear and can affect the handling of the vehicle and
stopping ability .
• Incorrect t ire pressures and /o r underinflat ion can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing lo ss of vehicle control .
• The driver is respon sible for the correct tire pressures for all
tires on the vehicle. The applicable pre ssure values are located on
a sticker on the driver 's side 8-pillar or on the inside of the fuel
filler flap .
• Only when all tires on the vehicle are filled to the correct pres
sure , the tire pressure monitoring system * can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage . Therefore it is essential that the driver observe
the specified tire pressure value s for the tires and the correct pres
sures for the function of the tire pressure monitoring system *.
• Always inflate tires to the re commended and correct tire pres
sure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot resulting in tread separation , sudden tire failure and loss
of control.
• Ex cessive speed and /overloading can cause heat build-up ,
s udden tire failure and lo ss of control .
• If the tire pres sure is too low or too high , the t ires will wear
prematurely and the vehicle will not handle well .
• If the tire is not flat and you do not have to change a wheel
immediately , drive at reduced speed to the nearest service station
to check the t ire pressure and add air as required.

=> & .
We recommend that all work on tires and wheels be performed by
an authorized Audi dealer. They are familiar with recommended
procedures and have the necessary special tools and spare parts as
well as the proper facilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about tech
nical requirements for installing or changing tires and rims.
Replacing tires and wheels
Tires should be replaced at least in pairs and not individually (for
example both front tires or both rear tires together).
Be sure to read and heed the information to the tire pressure moni
toring system* =>
page 301.
Always buy replacement radial tires that have the same specifica
tions as the tires approved for your vehicle by Audi. Replacement
tires must always have the same load rating specification as the
original equipment or approved optional tires listed in the table

U.S. DOT Tire Identification Number (TIN ) and tire
manufacture date
T his is the tire's "seria l number". It begins with the letters "DOT"
and indicates that the tire meets all federal standards. The next two
numbers or letters indicate the plant where it was manufactured,
and the last four numbers represent the week and year of manufac
ture. 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 manufac
turer. This information is used to contact consumers if a tire defect
requires a recall.
Audi Original tire
Tires with the identification "AO" or "RO" have been specially
matched with your Audi. We recommend using only these tires
because they meet the highest standards regarding safety and
driving characteristics when used correctly. Your authorized Audi
dealer will gladly prov ide 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 materia ls 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 qual ity grading for treadwear , traction, and
temperature resistance
Tread wear, traction and temperature grades=> page 303.
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 vehic le, make sure the
new rims also have these sensors. The sensors must be compatible
with the tire pressure monitoring system* on your vehic le.
If you instal l rims, which do not have the sensors, or have sensors
which are not compatible, then the tire pressure monitoring
system* wil l not work properly. In this case, the tire pressure moni
toring 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 secure ly mounted. We
recommend using factory instal led valve stem caps. Ask your autho
rized Audi dea ler to replace lost valve stem caps.
The installation of replacement tires with steel cord body p lies 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 vehic le. 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
t ire pressure monitoring system* may be damaged. .._

in percentage. Conventiona l tires have a height/width ratio of 60 or
m ore .
The performance of low -aspect -ratio tires is particularly sensitive to
improper inflation pressure . It is therefore important that low
aspect ratio tires are inflated to the specified pres sure and that the
i nflation pressure is regularly checked and maintained . Tire pres
sures should be checked at least once a month and alway s before a
long trip ~

In order to minimize t he occurrence o f impac t damage to the t ires
of your vehicle , we recommend that you observe the following
p recau tions:
• Always ma intain recommended inflation pressures . Check your
t ire pressure every 2,000 miles (3,000 k m) and ad d air i f neces sa ry .
• D rive careful ly on roads with potholes, deep gullies or ridges.
Th e impa ct from driving throug h or over such o bstacles can
