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 hold ing and safe handling when in good cond ition and prop­
erly inflated =>& .
We recommend that a ll 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 dea lers have the necessary info rmation about tech ­
nical requirements for insta lling or changing tires and rims.
R epl ac ing tires and wheels
Tires shou ld be replaced at least in pairs and not individual ly (for
examp le both front tires or both rear tires together).
Be sure to read and heed the tire pressure monitoring sys tem*
information=>

A lways buy replacement radial tires that have the same specifica ­
tions as the tires approved for your vehicle by Audi. Rep lacement
tires must always have the same load rating specification as the
origina l equipment or approved optional t ires listed in the table

models covered by your Owner's Literature.
The tire pressure labe l located either on driver's side 8 -pi llar or
inside the fuel fi ller flap(=>
page 246, fig. 174) lists the specifica ­
tions of the original equipment tires installed on your vehicle at the
ti me it was manufactured.
Federa l law requires tire manufacturers to place standardized infor ­
mation on the sidewa ll of all tires =>
page 254, fig . 177. This informa ­
t ion identifies and describes the fundamental characteristics, the
qua lity grade of the ti re and also provides a tire identification
number for safety standard certificat ion and in case of a recal l.
Tire specificat ions
Knowledge of tire specifications makes it easier to choose the
co rrect t ires . Radial tires have the tire specifications marked on the
sidewall, for example :
P225 / 45 R 17 91H XL
This contains the fo llowing informa tion:

& 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,
espe cially 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.
& WARNING (continued )
• 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 ,
including 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 .
• 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 and a factory-installed tire pressure monitoring
system* that indicates a loss of tire pressure . 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 . Mi xing 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 t ires), then
use the spare tire for a short period of time only and drive with extra
care. Replace the f lat tire with the tire matching the others on your
vehic le as soon as possib le.
• If you put different whee ls and tires on your vehic le (e .g. winter
whee ls and tires), you must be certain that the wheels and tires are
compatible with the tire pressure monitoring system*. Otherwise
the system will register a malfunction and a fault message wi ll be
displayed. For more information, contact your authorized Aud i
dea ler.
(D Note
• When installing new tires, be careful not to damage the valves or
tire pressure monitoring system* sensors.
• 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 th e sake of the environm ent
Dispose of o ld tires in accordance with the loca l 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 wal
l
between tread shoulder and maximum section width~
page 254,
fig. 177 .
For exa mple: Tread wear 200, Traction AA , Temperature A.
All passenger car tires must conform to Federal Safety Requ ire­
ments in addition to these grades.
T rea d w ear
The
tread wear grade is a comparative rating based on the wear rate
of the tire when tested under controlled condit ions on a specified
government test course .
Fo r example, a tire graded 150 wou ld wear one and one hal f (1 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actua l 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 .
Tr act ion
The
traction grades, from highest to lowest, are AA, A, Band C.
T hose grades represent the tire 's ability to stop on wet pavement as
measured under contro lled co nditions on specified government
test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance
~ & .
Temp erature
T he
temperature grades are A (the highest), B , and C , represent ing
the tire's resistance to the generation of heat and its abi lity to dissi ­
pate heat when tested under control led conditions on a specified
indoor laboratory test wheel.
Susta ined high temperature can cause the mater ial of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure~& .
T he grade C corresponds to a leve l of performance which a ll
passenger car tires must meet under the Federal Motor Vehicle

________________________________________________ T_ i _r_e _s_ a_n_ d_ w_ h_ e_e _ l_s __ lfll
•
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. •
Winter tires
Winter tires can improve vehicle handling on snow and
ice. At temperatures below 45 °F (7 °C) we recommend
changing to winter tires.
In some heavy snow areas, local governments may require true
winter or "snow" tires, those with very deeply cut tread. These tires
should only be used in pairs and be installed on all four wheels.
Make sure you purchase snow tires that are the same size and
construction type as the other tires on your vehicle.
I f your vehicle is equipped with all-wheel drive*, this will improve
traction during winter driving, even with the standard tires.
However, we strongly recommend that you always equip all four
wheels on your vehicle with correctly fitted winter tires or all-season
tires, when winter road conditions are expected . This also improves
the vehicle's braking performance and reduces stopping distances.
Summer tires provide less grip on ice and snow . Winter tires (snow tires) must always be fitted on all four wheels
.
Compatible tire pressure monitoring sensors* must be installed on
all four winter tires for the tire pressure monitoring system* to func­
tion properly ~
page 256.
Ask your authorized Audi dealer or qualified workshop for permitted
winter tire sizes . Use only radial winter tires.
Winter tires lose their effectiveness when the tread is worn down to
a depth of 0.157 inch (4 mm) .
Only drive with winter tires under winter conditions. Summer tires
handle better when there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C).
If you have a flat tire, see notes on spare wheel
~ page 254.
Please always remember that winter tires may have a lower speed
rating than the tires originally installed on your vehicle at the time
it was manufactured . Please see~
page 256, "Speed rating (letter
code)" for a listing of the speed rating letter codes and the
maximum speed at which the tires can be driven.
The speed rating letter code(~
page 256) is on the side wall of the
tire
~ page 254.
& 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 accident 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 _,,

ately.
• Winter tires have ma ximum speed rating that may be lower
than your vehicle' s maximum speed.
• Never drive faster than the speed for which th e winter or other
tire s installed on your vehi cle are rated.
& WARNING
Always adjust your driving to the road and traffic condit ions .
Never let the good acceleration of the winter tire s and all -wheel
d rive tempt you into taking extra risks. Always remember :
• When braking , an all -wheel drive vehicle handles in the same
way as a front drive vehicle .
• Drive carefully and reduce your speed on icy and slippery roads ,
even winter tires cannot help under black ice conditions.
<£> For the sake of the environment
Use summer tires when weather conditions permit. They are
quieter, d o not wear as quick ly a nd r educe fuel cons ump tion.•
Snow chains
Sn ow cha ins may be fitte d only to th e 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 cha ins, then you must install them on
the front wheels at least.
The s now chains mus t have low-pro file l inks and must not be thicker
than 0. 53 inch ( 13.5 mm), including the lock. Remove wheel
center covers and trim discs before putting snow
chains on y our vehicle =>
(D. For safety reasons cove r caps mus t
then be fitted over the wheel bo lts . These are avai lable from autho ­
r ized Audi deale rs .
& WARNING
Using the wrong snow chain s for your vehi cle or in stalling them
incorre ctly can increase the risk of loss of control leading to
serious personal injury.
• Snow cha ins are available in different sizes . Alw ays make sure
to follow the instructions provided by the snow chain manufac ­
turer .
• When driving with snow chains never drive faster than the
speed permitted for your specific snow chains .
• Always observe local regulations .
0 Note
• Remove snow c ha ins before driving o n roads not covered with
snow to avoid damaging tires and wearing the snow cha ins down

& 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

Tire pressure monitoring system *
Applies to vehicles: with tire pressu re mon ito ring system
General notes _J
Each tire, including the spare (if provided), should be checked
month ly 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 inflation 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 tellta le when one or more of your tires is significantly
under-inflated. Accord ingly, when the low t ire pressure te llta le i llu ­
minates, you should stop and check your tires as soon as possible,
and inflate them to the proper pressure . Driving on a significantly
under-inflated tire causes the tire to overheat and can lead to tire
failure . Under -inflation also reduces fue l 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 responsibi lity to maintain correct tire
pressure, even if under -inflation has not reached the leve l to trigger
illumination of the TPMS low tire pressure te lltale.
Your vehicle has also been equipped with a TPMS malfunction indi­
cator to indica te when the system is not opera ting proper ly . The
T PMS malfunction indicator is combined with the low tire pressure
t elltale. When the system detects a ma lfunction, the telltale w ill
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
be ab le to detect or signa l low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, inc luding the insta
llation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly . A lways
check the TPMS malfunction telltale after replac ing one or more
tires or whee ls on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TP MS to continue to function
proper ly. •
App lies to veh ic les: w ith tire pressure monitoring system
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving .
As soon as the tire pressure monitor ing syste m senses a signi ficant
loss of air pressure in one or severa l tires, text messages and yellow
symbols appear in the ins trument c luster dis play to alert the d river .
The warning light in the instrument cluster comes on when the
t ire is sig nificantly unde rinflated
~ page 12 .
The warn ing light { also i lluminates in the case of a system
malfunction.
Be aware that tire p ressu re is also dependent on the tempe ra ture of
the tire . For every 18 °F (1 O °Cl increase in tire temperature, tire pres ­
su re increases by about 1 .5 psi (0 .1 bar). The ti re wa rms up wh ile the
vehicle is moving and tire pressure rises. So you should adjust tire pressure only when they are
cold, when the temperature of the tires
is roughly the same as the ambient air temperature.
I n order to keep the tire pressure monitoring system properly cali ­
brated, tire pressure on all fou r tires sh ould be checked at regular
interva ls, adjusted if necessary, and saved in the proper setting
(recommended pressure)~
page 265.
The tire pressure is shown either on the driver's side B-pil lar or on
the inside of the fuel filler f lap . _..

& WARNING
• When the tire pressure monitoring system warning light is lit,
one or more of your tires is significantly underinflated. You should
stop and check your tires as soon as possible , and inflate them to
the proper pressure as indicated on the vehicle's tire pressure
label =>
page 246 . Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire failure. Underinfla­
tion also is likely to impair the vehicle's handling and stopping
ability.
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
~ For the sake of the environment
Driving with underinflated tires reduces fuel efficiency and tire
tread life.
[ i] Tips
• Each tire, including the spare , should be checked monthly when
the temperature of the tires is about the same as ambient air
temperature and set to the recommended inflation pressure as
specified on the tire pressure label=> page 246.
• Th e factory supplied spare wheel is equipped with a sensor for
the tire pressure monitoring system. As long as the spare wheel is
not mounted, the tire pressure of this tire will not be monitored.
• The tire pressure monitoring system helps the driver monitor tire
pressures, but the driver is still responsible for maintaining the
correct tire pressure.
• Tir e pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• When tires are replaced, the sensors and valves should not be
exchanged. The valve core, nut, valve sealing and seal washer (replacement kit) needs
to be replaced. If necessary, the valve and
the wheel electronics have to be replaced.
• Th e tire pressure monitoring system on your Audi was calibrated
using tires with the "AO" or "RO" identification. We recommend
using these tires.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system.
Otherwise the system will register a malfunction and a fault
message will be displayed. For more information, contact your
authorized Audi dealer.
• Adjust the tire pressure and store the pressure in the tire pres­
sure monitoring system to the load you are carrying .

[ i ] Tip s
• In the case of an intentiona l loss of air pressure, such as when
readjusting tire pressure, the pressure must be stored again after ­
ward =>
page 265.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• The ye llow symbol disappears when the tire pressure is
corrected and the new pressure is stored in the system=>
page 265.
• After changing a wheel or rep lacing a wheel with the spare tire
you have to adjust the tire pressures on all wheels . In addition, you
must then initialize the new tire pressures in the tire pressure moni ­
toring system=>

condition of yo ur veh ic le changes . Proceed as follows :
Corr ec ting tir e pressure
- Check the pressure in t he tires .
- Adjust air pressure as needed to comp ly with t he infor-
mation on the label located on the label located either on
