@ Audi Original Tires
Audi Original equipment tires
with the designation "AO" have
been specially matched to your
Audi. When used correctly, these
tires meet the highest standards
for safety and handling. An au­
thorized Audi dealer or author­
ized Audi Service Facility will be
able to provide you with more in­
formation.

New tires or wheels
Audi recommends having all work on tires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
knowledge and are equipped with
the required tools and replace­ ment parts.
... New tires do not yet have the
optimum gripping properties.
Drive carefully and at moderate
speeds for the first 350 miles
(500 km) with new tires .
... use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread pattern as possible on all four
wheels.
... use tires of the same construc­
tion, size (rolling circumference)
and the same tread pattern on
all four wheels.
... Do not replace tires individually.
At least replace both tires on the
same axle at the same time .

.,.Audi recommends that you use
Audi Original Tires. If you would like to use different tires, please
note that the tires may perform
differently even if they are the
same size
¢ &. -
... If you would like to equip your
vehicle with a tire/rim combina ­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service
Facility before making a pur­
chase¢

The spare tire* is different from
the regular tires installed on the
vehicle - for example, if winter
tires or wide tires are installed - so only use the spare tire* tempo ­
rarily in case of emergency and
drive carefully while it is in use . It
should be replaced with a regular
tire as soon as possible.
Applies to: vehicles with all wheel drive
All four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds . For this rea­
son, in case of emergency, only
use a spare tire* that is the same ...

8,_ WARNING , -
-Only use tire/rim combina-
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
-For technical reasons, it is not possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more
than six years old when abso­
lutely necessary and drive
carefully when doing so.
Wheels
-Do not use run-flat tires on
your vehicle. Using them when
not permitted can lead to ve­ hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage
Fig. 191 Tire profile: treadwear indica­
tor
Tire wear
Check the tires regularly for wear .
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear .
-Have an authorized Audi dealer
or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear. ..
219

Wheels
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear
more quickly.
Treadwear indicator
The original tires on your vehicle have 1/16 inch (1 .6 mm) high
"wear indicators" ¢fig.
191 run­
ning across the tread. Marks on
the tire sidewall (for example
"TWI" or other symbols) indicate
the positions of the tread wear in­
dicators.
The tires have reached the mini ­
mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones¢ .&..
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly . To rotate the tires,
install the tires from the rear axle
on the front axle and vice versa.
This will allow the tires to have approximately the same length of
service life.
1> Obey any applicable regulations in your
country.
220
For unidirectional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢page 248.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hidden . Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage . If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed .
&_ WARNING ~ -
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.
This can especially have a nega­
tive effect on handling, on the risk aquaplaning when driving
through water, when driving .,.

A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an acc ident. For the correct tightening specifi ­
cation, see ¢
page 244, After changing a
wheel .
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of grease.
- Only use wheel bolts that fit the rim .
- Always have damaged r ims repa ired by an
authorized Audi dealer o r autho rized Aud i
Service Facility . Never repair or d isassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
W inte r ti res s ignificantly improve the vehicle's
h andling when driving in win ter condit ions . Be­
cause of the ir constr uction (width, compound,
tread pattern), summer tires provide less trac­
tion on ice and snow .
... Use w inter t ires on all fo ur wheels .
... Only use winter t ires that are approve d for your
v ehicl e.
... Please note that the maximum permitted
speed may be lower with winter tires¢.&_ . An
authorized Aud i dealer or au thori zed Aud i Serv­
ice Fac ility can inform you about the maximum
permitted speed fo r your tires .
... Check the tire press ure after installing wheels
¢page 221.
The effectiveness of winter tires is reduced great­
l y when the tread is worn down to a depth of
0 .1 57 in ( 4 mm). The character ist ics of winter
tires a lso de crease great ly as the tire ages, re­
ga rdless of the remain ing tread.
WARNING
- Never drive faster than the maxim um per ­
mitted speed for your t ires. This cou ld cause
the tires to heat up too much. Th is increases
Wh eel s
the risk of an accident because it can cause
the t ire to burst.
- Always adapt your driving to the road and
traffic cond itions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter t ires can lose tract io n on black ice.
@ For the sake of the environment
Reinsta ll summer tires at the app ropr iate
time, beca use they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road no ise, tire wear and fue l
consumpt io n.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, on ly
winter tires w ith the
& symbo l may be per­
mitted .
Snow chains
Snow ch ains not o nly improve t he d riv in g in win ­
te r road condit ions, bu t also the braking .
... On ly install snow cha ins on the fron t wheels .
Th is applies a lso to vehicles with a ll w heel

... Check and correct the se ating of the snow
chai ns after driving a few feet, if necessary . Fol ­
low th e instructions from the manufacturer.
... Note the maximum speed of 30 mph (SO km/

Uniform t ire quality grading
- Tread wear
- T raction AA A B C
- T emperatu re ABC
Quality grades ca n be found where applicable on
the ti re side wall between tread shoulder and
maximum sect ion w idth
¢ page 211, fig. 190.
For example: Tread wear 200, Traction AA, Tem­
perature A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wea r
The
tr ead w ear grade is a comparat ive rating
based on the wear rate of the t ire when tested
under controlled conditions on a specified gov­
ernment test course.
F or examp le, a t ire graded 150 would wear one
and one ha lf
( 1 1/2) times as well on the govern ­
ment course as a tire graded
100 .
The relative perfo rmance of tires depends u po n
the actua l conditions of their use, however, and
may depart significant ly from the norm due to
va riations i n driving habits, service practices and
d ifferences in road characteristics and climate.
Traction
The
traction grades, from highest to lowest, are
AA, A, Band
C. T hose grades represent the tire's
ab ility to stop on wet pavement as measured un­
de r contro lled conditions on specified gove rn­
ment test surfaces of asphalt and concrete . A tire
marked C may have poor traction performance
¢ _& .
Temperatur e
The
temperature grades are A (the highest), B ,
and C, representing the tire's resistanc e to the
generation of heat and its ability to diss ipate
Wh eel s
heat when tested under cont rolled conditions on
a specified indoor laboratory test wheel.
Sustained high temperat ure can cause the mate­
r ia l of the tire to degenerate and reduce t ire life ,
and excessive tempera ture can lead to s udden
tire failure ¢,& .
T he grade
C corresponds to a level of perfo rm­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Sa fety Standa rd
No.
109. Grades Band A represent higher levels
of pe rformance on the laboratory test wheel than
the minim um req uired by law.
A WARNING
-
The tract ion grade assigned to this t ire is
based o n straight -ahead braking traction
tests, and does no t include acceleration, co r­
n ering, hyd roplaning or pea k traction cha rac­
t erist ic s .
A WARNING
The temperature grade fo r this tire is estab­
lished for a tire that is properly infl,;1ted and
not overloaded . Excessive speed, underinfl a­
tion, o r excessive loading, either separately or
i n comb inat ion, can cause heat bu ildup and
possib le tire fai lure .
A WARNING
-
-Temperature grades apply to tires that are
p roperly inf lated and not ove r or under inflat­
ed.

Tire pressure monitoring
system
ill General notes
Each tire, including the spare (if provided),
shou ld be checked monthly whe n cold and inflat­
ed to the i nflat io n press ure recommended by the
vehicle manufacturer on the veh icle placard or
t ir e inflation pressure labe l. (If your ve hicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determ ine the proper tire infla­
t ion pressure for those tires).
As an added safety feature, yo ur vehicle has been
equipped with a tire pressure mon itor ing system
(TPMS) that illuminates a low tire pressure tell­
ta le when one or more of your tires is signif icant­
ly under-inflated. According ly, when the low t ire
pressure te lltale illum inates, you sho uld stop and
chec k your tires as soon as possib le, and inflate
t h em to the prope r pressure. Dr iving on a sig nifi­
ca nt ly unde r-inflated t ire causes the t ire to over ­
hea t and can lead to tire fa il ur e. Under-inflat ion
also reduces fue l effic iency and tire tread life,
and may affect the vehicle's handling and stop -
ping ability .
liJJ,-
231

Wheels
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib ility to ma intain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your veh icle has also been equ ipped with a TPMS
malfunction indicator to indicate when the sys ­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire
pressure telltale . When the system detects a
malfunction, the telltale will flash for approxi­ mately one minute and then remain cont inuously
illum inated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunct ion indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS ma lfunctions
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 telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate t ires and
wheels a llow the TPMS to continue to function
properly.
Description
A pp lies to: ve hicles w ith tire p ressure monitoring system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The system uses sensors that measure the tem ­
perature and pressure in the tires . The data is
sent from these sensors to the contro l module by
radio frequency.
The Tire Pressure Monitoring System shows the current pressures and temperatures of the tir es
in the Infota inment system
c:> page 232. It also
compares the current t ire pressures with the
stored tire pressu res and gives a warning in the
d river information system if the tire pressure is
different from what is stored
r:';> page 233.
232
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must store the tire pressures again
c:> page 233:
-every time the tire pressures change, for exam ­
ple when the load in the vehicle changes,
- after replacing a tire, or
- if wheels with new whee l sensors are used.
_&. WARNING
- The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsib le for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is high. This could
result in serious damage to the tire and
even cause the tire to burst, increasing the
risk of an accident.
-A tire with low pressure flexes more. This heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acc i­
dent.
- The tire pressure monitoring system does
not warn about damage or defects in the
tire construct ion that could cause the tire to
burst, for examp le. Inspect your tires reg u­
larly.
(D Tips
- If tires are replaced, the sensors/valves do
not need to be removed or replaced. Just re­
placed the va lve stem and, if necessary, the
valve and the wheel electronics.
If you have
questions, see your authorized Audi dealer
or authorized Audi Service Facility.
- An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors rep laced by an authorized Audi
dealer or author ized Audi Service Facility.
