-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
Original equipment tires contain
treadwear indicators in the tread
pattern, which are bars that are
1/16 in (1.6 mm) high and are
spaced evenly around the tire per­
pendicular to the running direc­
tion¢ fig. 193. The letters "TWI"
or triangles on the tire sidewall
indicate the location of the tread­
wea r indicators.
The tires have reached the mini ­
mum tread depth l) when they
have worn down to the tread wear
indicators. Replace the tires with
new ones ¢ .&.
Wheel rotation
Rotating the wheels regularly is
recommended to ensure the tires
wear evenly. To rotate wheels, in­
stall the wheels from the rear
axle on the front ax le and vice
versa. This will allow the tires to
~ l) Obey any applicable regulations in your
:0 country . .....

length of service life.
F
or unidirectional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢ page 282.
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.

bel. The
Label is Located on the B­
pillar ¢fig. 194, ¢fig. 195.
Use the tire pressure specified for
a normal vehicle load when
the
vehicle is partially loaded ¢ table
on
page 262. If driving the vehi­
cle when fully loaded, you
must

increase the tire pressure to the
maximum specified pressure¢.&..
Checking/correcting tire
pressure
•Check the tire pressure at least
once per month and also check it
before every long drive.
•Always check the tire pressure
when
the tires are cold. Do not
reduce the pressure if it increas­
es when the tires are warm.
•Check the Label¢ fig. 195 for
the correct tire pressure based
on vehicle
Load.
•Correct the tire pressure if nec­
essary .
•Vehicles with Tire Pressure Mon­
itoring System*: store the modi­
fied tire pressure
in the Infotain­
ment system¢ page 269.
•Check the pressure in the emer­
gency tire*/spare tire*. Always
maintain
the maximum temper­
ature that is specified for the
tire.
A WARNING
r-=
Always adapt the tire pressure
to your driving style and vehicle
load.
-Overloading can lead
to loss of
vehicle control and increase .,.

available amount of cargo and
luggage load capacity.
For ex­
ample, if
the "XXX" amount
equals 1400 lbs and there will
be five 1

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them c::> .&..
&. 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 accident. For the correct tightening specifi­
cation, refer to c::> page 2 78, 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 rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never
repair or disassemble
rims yourself, because this increases the risk
of an accident.
· Winter tires
Winter tires significantly improve the vehicle's
handling
when driving in winter conditions. Be­
cause of their construction (width, compound,
tread pattern), summer tires provide less trac­
tion on ice and snow .
.,. Use winter tires on all four wheels.

Downloaded from www.Manualslib.com manuals search engine ~Only use winter tires that are approved for your
vehicle.
~Please note that the maximum permitted
speed may be lower with winter tires q ,&.. An
authorized Audi dealer or authorized Audi Serv­
ice Facility
can inform you about the maximum
permitted speed for your tires.
~Check the tire pressure after installing wheels
qpage260.
The effectiveness of winter tires is reduced great­
ly when
the tread is worn down to a depth of
0.157 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re­
gardless
of the remaining tread.
A WARNING
1-=---Never drive faster than the maximum per-
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
the risk
of an accident because it can cause
the
tire to burst.
- Always
adapt your driving to the road and
traffic conditions. Drive carefully and reduce
your speed on icy or slippery roads.
Even
winter tires can lose traction on black ice.
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free
of snow and ice. Summer
tires cause
Less road noise, tire wear and fuel
consumption.
(j) Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where
winter tires are required, only
winter tires with the & symbol may be per­
mitted.
Snow chains
Snow chains not only improve the driving in win­
ter road conditions, but also the braking.
~Only install snow chains on the front wheels.
This applies also
to vehicles with all wheel
drive*.
Wheels
~Check and correct the seating of the snow
chains
after driving a few feet, if necessary. Fol­
low
the instructions from the manufacturer.
~Note the maximum speed of 30 mph (50 km/
h). Note the Local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authori zed Audi dealer or author­
ized Audi Service Facility
to see if you may use
snow chains .
You must remove the snow chains on roads with­
out snow . Otherwise, you could impair driving
ability and damage the tires.
A WARNING
Using incorrect snow chains or installing snow
chains incorrectly
can result in loss of vehicle
control, which increases
the risk of an acci­
dent.
CD Note
- Snow chains can damage the rims/wheel
covers* if the chains come into direct con·
tact with them. Remove the wheel covers*
first. Use coated snow chains.
-
Using snow chains that add more than 0.53
in (0.53 in) of height can severely damage
the wheel housings and
other vehicle com­
ponents.
(D Tips
When using snow chains, it may be useful to
switch on sport mode ~page 88.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ra­
tio 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 au­
thorized Audi dealer
for more details .
The
Low aspect ratio of these tires is indicated by
a numeral
of SS or less in the tire's size designa­
tion. The numeral represents the ratio of the
tire's sidewall height in relation to its tread width..,.
265

expressed in percentage. Conventional tires have
a heig h
t/width ratio of 60 or more.
The performanc e o f lo w-a spect-ratio tires is par·
t icularly sensitive t o improper inflation pres·
sure. It is therefo re important that low aspect
ratio tires are inflated to the specified pressure
and that t h e inflation pressure is re g ula rly
chec k
ed and maintained. T ire pressure s should
be checked at least once a month and alway s
b efo re a l
ong trip Q page 260.
What you can do to avoid tire and rim
damage
L o w aspect ratio tires can be damaged more easi·
ly by impact with potholes, cu rbs, gull ies or
r i
dges o n th e roa d, pa rt ic u la rly ifthe tir e is un·
d e rinflated .
In order to minim ize the occu rrence of impact
damage to the ti res of your vehicle, we recom·
mend that you observe the fo llowi ng p recau ·
tions:
- Always
maintain recommended inflation p res·
sures. 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 impac t from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause
damage to your tires.
- Af t
er any impact, immediately inspec t your
tires o r have them inspected by the nearest au ­
thorize d Audi dealer. Replace a da maged t ir e as
soo n a s possib le.
- In sp e
ct yo ur tires e v ery 2 ,000 m iles (3 ,000 km)
fo r d
amage and wear. Damage is not always
e a sy to
see. Damage can lead to loss of air and
un
deri n flation, which could eventually cause
tire failure. If you believe that a tire may have
been damaged, replace the tire as soon as pos­
sible.
- These
tires may wear more quickly than others.
-Please also remember that, while these tires
deliver responsive handling, they may ride less
comfortably and make more no ise than other
choices.

Reduced performance in winter/co ld season
conditions
All ti res are designed fo r certain purposes. The
low
aspect ra tio, 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
tract ion under those conditions. We suggest you
use the re commended snow or all-season tires
spe cified for your vehicle, or their equiva lent.

- Temperatur e ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width Q page 250, fig. 192.
Fo r e xample: Tread wear 200, Traction AA, Tem ­
perature A.
All
passenger car t ires must conform to Federal
Sa f
ety Requirements in addi tion to these grades.
Tread wear
The tread w ear grade is a comparative rating
b
ase d on the wear rate of th e tire w hen tested
u nd er c
ontro ll ed cond iti ons o n a specified go v·
ernment test course.
For ex
ample, a tire graded 150 would wear o ne
and o ne ha lf (1 1/2) times as well on the govern ­
ment course as a tire graded 100.
The relative performance of tires depends upon
the a ctual conditions of their use, however, and
may depart significant ly from the norm due to
varia tions in driving habits, service practices and
differences in road characteristics and cl imate.
Traction
The traction grades, from highest to lowest, are

der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete. A tire
marked
C may have poor traction performance
c) .&..
Tempera ture
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory
test wheel.
Sustained high temperature can cause
the mate­
r ial of
the tire to degenerate and reduce tire life,
and excess i
ve temperature can lead to sudden
tire failur e
c) .&..
The grade C corresponds to a leve l of perform ­
ance which all passenger car tires
must meet un­
der
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.
A WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics.
&_WARNING
-1
The temperature grade for this tire is estab-
lished for a t
ire 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 t
ire failure.
&_WARNING
Temperature grades apply to tires that are
properly inflated and not over or under inflat­
ed.
Wheel s
Tire pressure monitoring
system
CD General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat ­
ed to
the inflation pressure recommended 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 pressure la­
bel, you shou ld determine
the proper tire infla­
tion 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 tell­
tale when one or more of your tires
is significant­
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them
to the proper pressure. Driving on a signifi ­
cantly under-inflated tire causes
the tire to over­
heat and can lead to tire failure . Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect
the vehicle's handling and stop­
ping ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it
is the driver's re­
spo nsibility
to maintain correct tire pressure,
even if under-inflation has
not reached the level
to trigger
illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped 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 continuously
illuminated. This sequence
will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When
the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended.
TPMS malfunctions
may occur for a variety of reasons, including
the ""'
267

installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPM S
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more ti
res or whee ls on your veh icle to ensure
that the replacement or alternate tires and
wheels
allow the TPMS to conti nue to functi on
p roper ly .
If the Tire Pressure Monitoring System
indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or
if there is a system malfunction.
Using the ABS sensors, th e tire p ressure monitor­
i n g
system compares the tire tread circumfer­
ence and vibra tion char
acteristi cs of the individ u­
al tires.
If the pressure changes in one or more
tires,
this i s indicated in the Infotainment system
d isp lay
with an ind icator light RI and a message .
If only one tire is affected , the location of that
tire will be ind icated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressu res
change (switching between partial and full load
pressure) or
after changing or replacing a tire on
your veh icle ¢ page 269. The tire pressure moni­
toring system only monitors the tire pressure you
