& WARNING
Incorrect tire pressures and /or underinflation can lead sudden tire
failure , loss of control , collision , serious personal injury or even
death .
• When the warning symbol appears in the instrument
cluster, stop and inspect the tires. • Incorrect tire pressure and/or underinflation can cause
increased tire
wear and can affect the handling of the vehicle and
stopping ability.
• Incorrect tire pressures and /or underinflation can also lead to
sudden tire failure , including a blowout and sudden deflation ,
causing loss of vehicle control.
• The driver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pressure values are located on
a sticker on the driver 's side 8-pillar.
• 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 e ssential that the driver observe the

specified tire pressure values for the tires and the correct pres
sures for the function of the tire pres sure monitoring system*.
• Always inflate tires to the recommended and correct tire pres
sure before driving off.
• Driving with underinflated tires bend more , letting them get
too hot re sulting in tread separation, sudden tire failure and loss
of control.
• Excessive speed and /overloading can cause heat build-up,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high, the tires 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 tire pressure and add air as required .

& WARNING
Overloading a vehicle can cause loss of vehicle control , a crash or
other accident, serious personal injury, and even death.
& WARNING (co ntinued )
• Carrying more weight than your vehicle was de signed to carry
will prevent the vehicle from handling properly and increase the risk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe di stance.
• Tires on a vehicle that has been overloaded can fail suddenly,
including 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 vehicle heavier than the
vehicle's Gros s 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. .-.
Page 307 of 370

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 placard (tire infla
tion pressure label) =>
page 299,
fig. 216.
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 =>
page 299, fig. 216.
4. The resulting figure equals the available amount of cargo and luggage load
capacity. For example, if the
"XXX"
amount equals 1400 lbs. and there will be five 150 lbs . passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs.
(1400-750 (5
X 150) = 650 lbs.)
Safety first
Tires and wheels -
5. Determine the combined weight of
luggage and cargo being loaded on the
vehicle. That weight may not safely exceed the available cargo and luggage
load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer ,
load from your trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the available cargo and luggage load capacity of your
vehicle.
- Check the tire sidewall(=>
page 307,
fig. 220) to determine the designated load rating for a specific tire . •

Tire service Life
The servi ce life of tires depends on a lot of different
things including proper installation and balancing,
correct tir e pressure and driving style.

The original t ires o n your veh icle have 1/16 inch ( 1.6 mm) h igh "wear
ind icators"~ fig. 218 running across the tread . Depending on the
ma ke, there w ill be six to eight of them even Ly placed around the ti re.
Marks on the t ire sidewall (for examp le "TWI " or other symbols) indi
cate the positions of the tread wea r indicators . Worn t ires must be
replaced. Differe nt figu res may apply in other countries ~ & .
Tire pressure
Incorrect tire pressure causes premature wea r and can cause sudden
tire blow-o ut. Fo r th is reason, tire pressu re must be checked at least
once a mont h
~ page 302.
Driving style
Driving fast aro und curves, heavy acceleration and hard b raking
increase tire wear .
Rotating tires for more even wear
For all four tires o n your ve hicle to have the same se rvice life, we
recommend that the fron t and rear t ires are rot ated according to the
tire manufact urer's suggested tire rotat ion intervals . Please
remember the fo llow ing :
• Tir e ro tat ion inte rvals may d iffe r from the vehicle serv ice intervals
out lined in your Maintenance and Warranty Booklet .
• The longer one tire is used in one locat ion on the vehicle, the more
it wears at certain points; therefore, we recommend that you follow
the t ire manufacture r's sugges ted tire rotation interva ls .
• Vehicles with front-whee l drive experience more tread wea r on the
front wheels compa red to a ll-wheel dr ive (quattro ®).
• Please ro ta te tires as shown~ fig. 219 .
• Extra care must be taken when rotating direction -specific t ires
~ page 325 .
Wheel balancing
The wheels on new vehicles are balanced. However, var ious si tuatio ns
dur ing everyday driving can cause them to become unbalanced,
resu lting in v ibr ations yo u can us ua lly fee l throug h the stee rin g
w heel.
Unbalanced whee ls mus t be rebalanced to avoid excessive wea r on
steeri ng, suspension and tires . A wheel must also be rebalanced
when a new tire is installed.

Incorrect wheel alignment
In correct whee l al ignme nt can ca use excessive tir e wea r, impairing
th e sa fety o f the vehicl e. If t ires show excessive w ear, hav e the w heel
alignment checked by a n authorized A udi dea ler or qualifie d work
shop.
All Wheel Drive
Vehicles wi th quattro® must always have tires of the same size ,
con st ruct ion an d tread type . For details see~
page 248.
& WARNING
Sudden tire failure can lead to los s of control, a cra sh and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chemicals that can cause t ire damage, such as
grease , oil, gasoline and brake fluid away from tires.
• 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 failu re and loss of vehicle control. •

The tires and rims are essential parts of the vehicle's design . The tires
and rims approved by Audi are specially matched to the characteris
tics of the vehicle and can make a major contribution to good road holding and safe handling when in good condition and properly
inflated
~ & .
We recommend that all work on tires and wheels be performed by an
authorized Audi dealer . They are familiar with recommended proce
dures 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 314.
Always buy replacement radial tires that have the same specifications
as the tires approved for your vehicle by Audi. Replacement tires must
always have the same load rating specification as the original equip
ment or approved optional tires listed in the table~
page 299.
Audi-approved specification tires are specially matched to your
vehicle and its load limits, and can contribute to the important road- holding, driving characteristics, and safety of the vehicle
. The table
(~ page 299) lists specifications of the tires approved for the Audi
models covered by your Owner's Literature.
The tire pressure label located on driver's side B-pillar (~
page 299,
fig. 217) lists the specifications of the original equipment tires
installed on your vehicle at the time it was manufactured.
Federal law requires tire manufacturers to place standardized infor
mation on the sidewall of all tires~
page 307, fig. 220 . This infor
mation identifies and describes the fundamental characteristics, the
quality grade of the tire and also provides a tire identification number
for safety standard certification and in case of a recall.
Tire specifications
Knowledge of tire specifications makes it easier to choose the correct
tires . Radial tires have the tire specifications marked on the sidewall,
for example:
P245 / 45 R 17 99 H XL
This contains the following information:
P Indicates the tire is for passenger cars (where applicable)
245 Nominal tire width in mm of the tire from sidewall edge to side-
wall edge. In general, the larger the number, the wider the tire
45 Height/width ratio in percent (aspect ratio)
R Tire construction : Radial
17 Rim diameter code (in inches)
99 Load rating code
H Speed rating letter code
XL (or "xl", "EXTRA LOAD", or "RF") indicates that the tire is a"Rein
forced" or an "Extra Load" tire
M+S (or "M/S") Indicates that the tire has some mud and snow capa
bility
The tires could also have the information of direction of rotation
~page 295.

Tire manufacturing date
The manufacturing date is also indicated on the tire sidewall
(possibly on ly on the
inner s ide of the wheel):
"DOT ... 2210 ... " means, for example, that the tire was produced in
the 22nd week of 2010.
Speed rating (letter code)
The speed rat ing letter code on the wheels ind icates the maximum
permissible road speeds =>
& in "Winter tires" on page 311.
P up to 93 mph (150 km/h)
Q up to 99 mph (158 km/h)
R up to 106 mph (170 km/h)
S up to 110 mph (180 km/h)
T up to 1 18 mp h (190 km/h)
U up to 124 mph (200 km/h)
H up to 130 mph (210 km/h)
V up to 149 mph (240 km/h)3>
Z over 149 mph (240 km/h)3>
W up to 168 mph (270 km/h)3>
Y up to 186 mph (298 km/h)3>
Your vehicle is normally factory equipped with t ires, which possess
excellent driving characterist ics and give you r A udi optimum driv ing
comfort. An electronic speed limiter=>
page 23 will normally prevent
your vehicle from going faster than the tire speed rating =>
&-
U.S. DOT Tire Identification Number (TIN) and tire
manufacture date
This is the tire's "serial number". It begins with the letters "DOT" and
indicates that the tire mee ts all federal standa rds. The next two
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 2210 mean that the tire was produced in
3
l For tires w ith a maxim um speed capabi lity ove r 149 mph (240 km/h), tire
manufacture rs sometimes use the letters "ZR."
Safety first
the 22nd week of 2010 . The other numbers are marketing codes that
may or may not be used by the tire manufacturer . This i nformation 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 w ith your Audi. We recommend using only these tires
because they meet the highest standards regard ing safety and
driv ing characteristics when used correct ly. Your authorized Audi
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 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 310.
Maximum Permissible Inflation Pressure
Th is number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
& 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. _,.

& WARNING (conti nu ed )
• Alway s use tire s, rim s and wheel bolts that meet the specifica
tions of original factory-installed tires or other combinat ions 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 speed s. 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 tir es on your vehicle if you are not sure of
their "previous history. " Old used t ires m ay have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• All four wheels must be fitted with radial tires of the same
type , size (rolling circumference) and the same tread pattern .
Driving with different tire s reduces vehicle handling and can lead
to a loss of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle - for example w ith winter tires - only use the spare
tire for a short period of time and drive with extra care. Refit the
normal road wheel as soon as safely possible.
• Never drive fa ster than the maximum speed for which the tires
on your vehicle are rated because ti re s that are driven faster than
their rated speed can fail suddenly.
• Overloading tire s cause heat build-up, sudden tire failure,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properl y inflated
and not over or underinflated.
• For technical reasons it is not always possible to u se wheels
from other veh icles- in some cases not even wheels from the same
vehicle model.
• If you install wheel tr im discs on the vehicle wheels , make sure
that the air flow to the brakes i s not blocked . Reduced airflow to
the brakes can them to overheat, increasing stopping distances
and cau sing a collision.
& W ARNING (continued )
• Run flat ti res may only be used on vehicles that were equipped
with them at the factory. The vehicle must have a chassi s designed
fo r run flat tires. Inco rrect use of run flat tires can lead to vehicle
damage or accidents. Che ck with an author ized Audi dealer or tire
specialist to see if your vehicle can be equipped with run flat tires .
If run flat tire s are u sed, they must be installed on all four wheels.
M ixing t ire types is not permitted.
0 Note
• For tech nica l reasons, it is not generally poss ible to use the wheel
r ims from o ther veh icles . T his ca n hold t rue for w heels of the same
veh icle type.
• If the sp are tire is different fr om the tires t hat yo u have mo unted
on your vehicle (for example w inter t ires or wide profile tires), then
use the s pare tire for a shor t perio d of tim e on ly and drive wi th ext ra
care. Replace t he flat tire w ith the tire matching the others on your
vehicle as soon as possible.
• Never dr ive witho ut the valve stem cap . The valves could get
