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 336.
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 327. ~

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 321) 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 8 -pillar (=>
page 321,
fig. 248) lists the specifications of the original equipment tires
installed on your vehicle at the time it was manufactured.
Federa l law requires tire manufacturers to place standardized infor ­
mation on the sidewall of al l tires=>
page 329, fig. 251. This informa­
tion identifies and describes the fundamental characteristics, the
quality grade of the tire and also provides a t ire 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
sidewa ll, 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 "xi", "EXTRA LOAD", or "RF") indicates that the tire is a"Rein ­
forced" or an "Extra Load" tire
M+S (or "M/S"l Indicates that the tire has some mud and snow capa­
bility
The tires could a lso have the information of direction of rotation
=>
page 317. Tire
manufacturing date
The manufacturing date is also indicated on the tire sidewall
(possibly only on the
inner side of the wheell:
"DO T ... 2208 ... " means, for example, that the tire was produced in
the 22nd week of 2008.
Speed rating (letter code)
The speed rating letter code on the wheels indicates the maximum
permissible road speeds=>
& in "Winter tires" on page 333.
P up to 93 mph ( 150 km/h)
Q up to 99 mph (158 km/h)
R upto 106mph(170km/hl
S upto110mph(180km/hl
T upto118mph(190km/hl
U up to 124 mph (200 km/h)
H up to 130 mph (210 km/h)
V up to 149 mph (240 km/h)31
Z over 149 mph (240 km/h)31
W up to 168 mph (270 km/h)3

Y up to 186 mph (298 km/h)31
Your vehicle is normally factory equipped with tires, which possess
excellent driving characteristics and give your Audi optimum
driving comfort. An electronic speed limiter:::>

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 meets all federa l 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-

& 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 (continued )
• Always use tires, rims and wheel bolts that meet the specifica­
tions of original factory -installed tires or other combinations that
have been spec ifically approved by the veh icle 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.
• All four wheels must be fitted with radial tires of the same type ,
size (rolling circumference ) and the same tread pattern. Driving
with different tires 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 with 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 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 ,
includ ing a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated and
not over or underinflated .
• For technical reasons it is not always possible to use wheels
from other vehicles -in some cases not even wheels from the
same vehicle model.
• 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.

Vehicle care I t •

-Tires and wheels
PW-------------------
& WARNING (continued)
• Run flat tires may only be used on vehicles that were equipped
with them at the factory. The vehicle must have a chassis designed
for run flat tires. Incorrect use of run flat tires can lead to vehicle
damage or accidents. Check with an authorized Audi dealer or tire
specialist to see if your vehicle can be equipped with run flat tires.
If run flat tires are used, they must be installed on all four wheels.
Mixing tire types is not permitted.
0 Note
• For technical reasons , it is not generally possible to use the
wheel rims from other vehicles. This can hold true for wheels of the
same vehicle type .
• If the spare tire is different from the tires that you have mounted
on your vehicle (for example winter tires or wide profile tires), then
use the spare tire for a short period of time only and drive with extra
care. Replace the flat tire with the tire matching the others on your
vehicle as soon as possible.
• Never drive without the valve stem cap. The valves could get
damaged.
~ 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 329,
fig. 251 .
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 ti re graded 150 wou Id 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 ass igned to this t ire i s based on straight -ahead
braking traction tests, and does not include acceleration,
c ornering , hydroplaning or peak tra ction chara cteristic s.
& WARNING
The temperature grade for this t ire is established for a tire that is
properly inflated and not overloaded. Excessive speed , underinfla ­
tion , or ex ces sive loading , either separately or in combination , can
c ause heat buildup and possible tire failure . •
Winter tires
Wi nter tires c an im prove vehicle handli ng on snow and
ic e. At t emperatures below 4 5 °F (7 ° C) we re commend
cha ngi ng to winte r tires.
In some heavy snow areas, local governments may require true
winter o r "snow" tire s, those with ve ry deeply cut tread. These tires
s h ou ld on ly be used in pairs and be i nstalled on all four wheels .
M ake sure you purchase snow tires that are the same si ze and
co nstruction type as t he o the r tires on your veh icle .
I f your vehicle is equipped with all -wheel drive *, this will improve
t raction d uring win te r dr iving, eve n with the s ta n dard t ires .
However, we strongly recommend that you always equip a ll four
w hee ls on you r vehic le wi th cor rec tly fi tted w inter tire s or all-season
t ir es, when w inter road co nditions ar e expec ted . T his also improves
the vehicle 's br aking perfo rmance and reduces stopping distance s.
Summer tires p rov ide less gr ip on ice a nd sno w.
Winter tires (snow tires) must a lways be fitted on all four whee ls .
Ask you r author ized Aud i deale r o r qualified wo rksho p fo r pe rmitted
winter tire sizes . Use only rad ial wint er tires. Winter tires
lose their effec tiveness when the tread is worn down to
a depth of 0 .1 57 inch (4 mm).
Only drive with w inter tires under winter conditions. Summer tires
handle better when there is no snow or ice on the roads and the
t emperature is above 45 °F (7 °C).
I f you have a flat tire, see notes on spare whee l
~ page 329.
Please always remember that winter tires may have a lower speed
rating than the tires original ly installed on your vehicle at the time
it was man ufact ured. Please see~
page 330, "Speed rating (lette r
code)" for a l ist ing o f th e speed rati ng lette r codes a nd the
maximum speed at which the tires can be driven.
The s peed rati ng letter code(~
page 320) is on th e sid e wa ll o f the
tire
~ page 329 .
& WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle' s maximum speed. Always know the maximum speed
before driving off . Never drive faster than the speed permitted for
your specific winter tires. This will cause damage to the tires
leading to an acc ident and serious personal injury to you and your
passengers .
& WARNING
Driving faster than the maximum speed for which the winter tires
on your vehicle were designed can cause tire failure including a
blowout and sudden deflation , loss of control , crashes and serious
personal injuries . Have worn or damaged tires replaced immedi ­
ately.
• Winter tires have max imum speed rating that may be lower
than your vehicle' s maximum speed.
• Never drive faster than the speed for which the winter or other
tires installed on your vehicle are rated . ...

& WARNING
Always adjust your driving to the road and t raffic condit ions .
Never let the good a cceleration of the winter tires and all -wheel
dri ve tempt you into tak ing extra ri sk s. Always remember :
• When braking, an all -wheel drive vehicle handles in the same
way as a front drive vehicle .
• Drive carefully and redu ce your speed on icy and sli ppery roads ,
even winter tires cannot help unde r bla ck ice conditions.
c£> For the sake of the environment
Use summer tires when weather conditions permit. They are
quieter, d o no t wear as quick ly a nd re duce fuel consump tio n.•
Snow chains
Snow cha ins may be fitte d o nly to the fron t whee ls, and o nly to
certain tire sizes . Ask your authorized Audi dealer on which tire
s iz es snow c hains can be used.
If you are going to use snow chains, then you must install them on
the front wheels at least.
The snow cha ins must have low -profile l inks and must not be thicker
than 0 .53 inch ( 13.5 mm), including the lock.
Remove wheel center c overs and trim discs before putt ing snow
chains on your vehicle~
0 . For safety reasons cover caps must
then be fitted ove r the wheel bo lts . These are avai lable from autho­
r ized Aud i dealers.
& WARNING
Using the wrong sno w chains for your vehi cle or installing them
incorre ctly can in crease the risk of loss of control leading to
serious personal injury .
& WARNING (continued )
• Snow chains are available in different sizes. Alw ay s make sure
to follo w the instructions provided by the snow chain m anufac ­
turer .
• When driving with snow cha ins never drive faster than the
s peed permitted for your specific snow chains .
• Alway s observe lo cal regu lations.

Wheel bolts
Wheel bolts must always be tightened to the correct
torque.
The design of wheel bolts is matched to the factory installed rims. If
different rims are fitted, the correct wheel bolts with the right length
and correctly shaped bolt heads must be used. This ensures that
wheels are fitted securely and that the brake system functions
correctly.
In certain circumstances, you may not use wheel bolts from a
different vehicle - even if it is the same model~
page 374.
& WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control, a collision and serious personal injury.
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened.
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque.
• Only use wheel bolts that belong to the rim being installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss.
If the tightening torque of
the wheel bolts is too low, they can loosen and come out when the
vehicle is moving. If the tightening torque is too high, the wheel bolts and threads can be damaged and the wheel can become
loose.
0 Note
The specified torque for the wheel bolts is 90 ft lb (120 Nm) with a
tolerance of ± 7,4 ft lb(± 10 Nm). Torque wheel bolts diagonally.
After changing a wheel, the torque must be checked as soon as possible with a torque wrench
-preferably by an authorized Audi
dealer or qualified workshop. •
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
have been thoroughly tested and been selected specifically for your
model for their superb performance, road feel and handling under
a variety of driving conditions. Ask your authorized Audi dealer for
more details.
The low aspect ratio of these tires is indicated by a numeral of 55 or
less in the tire's size designation. The numeral represents the ratio
of the tire's sidewall height in relation to its tread width expressed
in percentage. Conventional tires have a height/width ratio of 60 or
more.
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 pressure and that the
inflation pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and always before a
long trip~
page 323, "Checking tire pressure" .
What you can do to avoid tire and rim damage Low aspect ratio tires can be damaged more easily by impact with
potholes, curbs, gullies or ridges on the road, particularly if the tire
is underinflated.
In order to minimize the occurrence of impact damage to the tires
of your vehicle, we recommend that you observe the following
precautions:
• Always maintain recommended inflation pressures . Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary.
• Drive carefully on roads with potholes, deep gullies or ridges.
The impact from driving through or over such obstacles can
damage your tires. Impact with a curb may also cause damage to
your tires. ..,
Vehicle care
I t •

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
• After any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a
damaged tire as soon as possible.
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see . Damage can lead to loss of
air and underinflation, which could eventually cause tire failure . If
you believe that a tire may have been damaged, replace the tire as
soon as possible.
• These tires may wear more quickly than others.
• Please also remember that, while these tires deliver responsive
handling, th ey may ride less comfortably and make more noise than
other choices.
Reduced performance in winter/cold season
conditions
All tires are design ed for certain purposes. The low aspect rat io ,
ultra high performance tires originally installed on your vehicle are intended for maximum dry and wet road performance and handling.
They are not suitable for cold, snowy or icy weather conditions. If
you drive under those circumstances, you should equip your vehicle
with all -season or winter tires, which offer better traction under
those conditions . We suggest you use the recommended snow or
all -season tires specified for your vehicle, or their equivalent .
Refer to~
page 333for more detailed information regarding winter
tires. •
Tire pressure monitoring system
General notes U
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure recom ­
mended by the vehicle manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires of a different size
than the size indicated on the vehicle placard or tire inflation pres- sure label, you should determine the proper tire i
nflation pressure
for those tires.)
As an added safety feature , your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires is significantly
under -inflated . Accordingly, when the low tire pressure telltale illu ­
minates, you should stop and check your tires as soon as possible,
and inflate them to th e proper pressur e. Driving on a signi ficantly
under-inflated tire causes the tire to overheat and can lead to tire
failure . Under-inflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte­
nance, and it is the driver's responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pr essure telltale.
Your vehicle has also been equipped with a TPMS malfunction indi ­
cator to indicate when the system is not operating properly . The
TPMS malfunction indicator is combined with the low tire pressure
telltale . When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously
illuminated . This sequence will continue upon subsequent vehicle
start -ups as long as the malfunction exists .
When the malfunction indicator is illuminated, the system may not
b e able to de tect or signal low tire pr essure as in tended. TPMS
malfunctions may occur for a variety of reasons, including the
installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. Always
check the TPMS malfunction tell tale af ter replacing one or more
tires or wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to function
properly. •
