& 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.

Tires and vehicle load limits
There are li m its to the a mou nt o f load or weig ht th at any ve hic le and
any tire can carry . A vehicle that is overloaded wil l not handle wel l
and is more diff icu lt to stop . Overload ing ca n no t only lead to loss
of vehic le control, but can also damage important parts of the
ve hicle a nd can lead to sud den tire failu re, i nclu di ng a bl owou t and
sudden deflat ion that can cause the vehic le to crash.
Your safety an d that of your passengers also depends on ma kin g
su re tha t load l imits are not exceeded . Vehicle load includes eve ry ­
body and everything in and on the vehic le. These load limits are
t echnica lly re ferred to as the ve hicle's

& WARNING
Overloading a vehicle can cause loss of vehicle control , a crash or
other accident, serious personal injury , and even death.
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the
ri sk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle with in a safe distance .
• Tires on a vehicle that has been overloaded can fail suddenly ,
in cluding a blowout and sudden deflation , causing loss of control
and a crash .
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi cle heavier than the
vehicle's Gross Vehicle Weight Rating. •
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and luggage or other things that you plan to
transport so that you can make sure that
your vehicle will not be overloaded.
Steps for Determining Correct Load Limit
1. Locate the statement "THE COMBINED
WEIGHT OF OCCUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX
LBS "on your vehicle's pla card (tire infla ­
tion pressure label)=> page 291, fig. 229.
2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from
"XXX" kilo­
grams or
"XXX" pounds shown on the
sticker =>

The tires and rims are essential parts of the vehicle's design . The
tires and rims approved by Audi are specially matched to the char ­
acteristics of the vehicle and can make a major contribution to good
road holding and safe handling when in good condition and prop ­
erly inflated
=> & .
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
=> page 291. ~

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. .._

& WARNING
• Using incorrect or unm atched t ires and / or wheels o r improper
tire and wheel combinations can lead to lo ss of control , collision
and se rious per sonal injury .
• Always use tires , rim s and wheel bolts that meet the specifica ­
t ions of original f actory -installed tire s or other combinations that
have been spe cifically approved by the vehicle manufacturer .
• T ires age even if they are not being used and can fail suddenly ,
especially at high speeds . Tires that are more than 6 years old c an
only be used in an emergen cy and then with spec ial care and at
lower speeds .
• Never mount used tires on your vehi cle if you are not sure of
their "previou s history." Old used tires may have been damaged
e ven though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• All four wheels must be fitted w ith radial tires of the same type ,
size (rolling circumference ) and the same tread pattern . Driving
with different tires reduces veh icle handling and can lead to a loss
of control.
• If the spare t ire is not the same as the tires that are mounted
on the vehicle -for example with winter tires -only use the spare
tire for a short period of time and drive with e xtra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the ma ximum 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,
in cluding a blowout and sudden deflation and lo ss of control.
• Tempe rature grades apply to tires that are properly inflated and
not over or under inflated .
• For technical reasons it i s not always po ssible to use wheel s
from other veh icles - in some cases not even wheels from the
same vehicle model .
& WARNING (continued )
• If you install wheel trim discs on the vehicle wheels, make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision .
• Run flat tires may only be used on vehicles that were equipped
with them at the factory . The vehicle must have a cha ssis designed
for run flat tires and a fa ctory-installed tire pressure monitoring
system* that indicates a loss of tire pressure. Incorrect use of run
flat tires can lead to vehicle damage or acc idents . Check with an
authorized Audi dealer or tire specialist to see if your vehicle can
be equ ipped with run f lat tires . If run flat t ires are used , they must
be installed on all four wheels . Mixing tire types is not permitted.
0 Note
• For technical r eas ons, it is not gen erally possible t o us e the
whee l rims from other veh icles . ihis can ho ld true for whee ls of the
same veh ic le type.
• I f the spare tire is different from the tires that you have mounted
o n yo ur vehicl e (f or example wi nter tires or wide p rofile t ires), then
use the spare tire for a short period of time on ly and drive with extra
care . Rep lace the flat tire wi th the ti re m atchi ng t he o thers on you r
vehic le as soon as possib le.
• I f you should put diff ere nt w heels and tires o n your v ehicle (e. g.
winter wheels and tires), you must be certain that the wheels and
t ires are c ompatib le wi th the tire p ressu re monitoring system* .
Otherwise the system will register a malfunction and a fau lt
mes sage will be displayed . For more info rmation, contact your
author ized Aud i dea ler.

•
• Never drive without the valve stem cap. The valves could get
damaged.
• If the sensors must be replaced, then the valve must also be
replaced at the same time.
For the sake of the environment
Dispose of old tires in accordance with the local requirements. •
Uniform tire quality grading
• Tread wear
• Traction AA A B C
• Temperature A B C
Quality grades can be found where applicable on the tire side wall
between tread shoulder and maximum section width~
page 299,
fig. 233.
For example: Tread wear 200, Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Require­ ments in addition to these grades .
Tread wear
The
tread wear grade is a comparative rating based on the wear rate
of the tire when tested under controlled conditions on a specified
government test course.
For example, a tire graded 150 would wear one and one half (1 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual condi ­
tions of their use, however , and may depart significantly from the
norm due to variations in driving habits, service practices and differ ­
ences in road characteristics and climate. Traction
The
traction grades, from
highest to lowest, are AA, A, Band C.
Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government
test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance~& .
Temperature
The
temperature grades are A (the highest), B, and C, representing
the tire's resistance to the generation of heat and its ability to dissi­
pate heat when tested under controlled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure=>&.
The grade C corresponds to a level of performance which all
passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades Band A represent higher levels of
performance on the laboratory test wheel than the minimum
required by law .
& WARNING
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics .
& WARNING
The temperature grade for this tire is established for a tire that is
properly inflated and not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or in combination, can
cause heat buildup and possible tire failure. •
