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. 283. The letters "TWI"
or triangles on the tire sidewall
indicate the location of the tread­
wear indicators.
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
c;, .&..
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.
For unidirectional tires, make
sure the tires are installed accord-
1> Obey any applicable regulations in your
country.

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 indica te 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 increase the risk of an
accident because it has a nega­
tive effect on handling, driving
through curves, and braking,
and because it increases the
risk of hydroplaning when driv­
ing through deep puddles.

The correct tire pressure for tires
installed at the factory is listed on
a
label ¢ fig. 284. The sticker is
located on the door pillar (driver's
side)¢ fig. 285. The location may
vary depending on the model.
Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially loaded
¢ table
on page 353.
If driving the vehi­
cle when fully loaded, you must increase the tire pressure to the
maximum specified
pressure ¢,&. .
Checking/correcting tire
pressure
Wheels
.. 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. 285 for
the correct tire pressure based on vehicle load .
.. correct the tire pressure if nec ­
essary .
.. store the new tire pressure in
the Infotainment system
¢ page 361 .
.. Check the pressure in the spare
tire (compact spare tire)*. Al­
ways maintain the maximum
temperature that is specified for
the tire.
A WARNING
Always adapt the tire pressure
to your driving style and vehicle load.
-Overloading can lead to loss of vehicle control and increase
the risk of an accident. Read and follow the important safe­
ty precautions
in¢ page 355,
Tires and vehicle load limits.
351

Wheels
-The tire must flex more if the tire pressure is too low or if
the vehicle speed or load are
too high . This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­
ing, and the information is sub­
ject to change. If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side 8-
pillar, always follow the specifica­
tion on the 8-pillar label
¢ page 351, fig. 284.
352
(i} For the sake of the environment
-Tire pressure that is too low
increases fuel consumption.
-Fuel consumption may also in­
crease when driving with the
comfort tire pressure is se­
lected .
(D Tips
Audi recommends using the
tire pressure specified for a
normal load
¢ table on
page 353
or for a full load
when the vehicle is partially loaded.
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.
The following table lists recom­ mended tire pressures in cold
tires according to the load and
the size of the tires installed.

Tires and vehicle load limits
There are limits to the amount of load or weight that any vehicle
and any tire can carry . A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 150 lbs (68 kg) for each passen-
Wheels
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle . If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compli­ ance sticker on the front end of
the driver's door.

Wheels
A WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed 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 distance.
-Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to­
tal load being transported
-
includ ing the weight of a trail­
er hitch and the tongue
weight of a loaded trailer
-
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas -
356
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload­
ed.
Steps for Determining Correct Load Limit
1. Locat e the statement "THE
COMBINED WEIGHT OF OCCU­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS" on your vehicle's placard
(tire inflation pressure label)
Q page 351, fig. 285.
2.
Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the stick­
erQ page 351, fig. 285.
4. The resulting figure equals the
available amount of cargo and luggage load capacity. For ex­
ample, 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.

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/t ighten
eas ily.
Rims
Rims with a bolted rim ring " or with bolted wheel
covers* consist of m ultip le pieces . These compo­
n ents were bolted together using specia l bolts
a nd a special procedure . You must not repair or
d isassemble
t h em ¢.&. .
_& WARNING
Wheel bolts tha t are t igh tened or re paired in­
c orrectly can be come loose and result in loss
Wh eel s
of vehicle contro l, wh ich increases the risk of
an accident. For the cor rect tighten ing spec ifi­
cation, see
c:> page 374, Finishing.
- Always keep the wheel bolts and the
threads in the wheel h ub clean and free of
grease.
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
author ized Audi dealer or author ized Audi
Serv ice Facility. Never repair o r disassemb le
rims yourself, because th is increases the r isk
of an acc ident .
Winter tires
Winter tires significantly imp rove the vehicle 's
handling when dr iv ing in winter conditions . Be­
ca use of their const ruct ion (w idth , compou nd,
t read pattern), s ummer tires prov ide less t rac­
t ion on i ce and snow.
.,. Use winter tires on all four wheels .
.,. Only use winter tires that are app roved for yo ur
ve hicle.
.,. Please no te that the max imum permi tted
speed may be lowe r with winter tires
c:> .&_ . An
authoriz ed Audi dealer or authorized A udi Serv­
ice Facility can inform yo u about the maximum
permitted speed for your tires .
.,. Check the tire pressure after insta lling wheels
c=> page351 .
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.16 in (4 mm). The characteristics of w inter
tires also decrease greatly as the tire ages, re ­
gardless of the rema ining t read .
_& WARNING
-
- Never d rive fa ster than the max imum pe r­
mitted spee d for your tires. This could c ause
the t ires to he at up too mu ch. This inc reases
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 spee d on icy or slippery roads . Even
winter t ires can lose t ract ion on black ice.

Wheels
@ For the sake of the environment
Reinstall su mmer tires at the appropriate
time, because they pro vide better handling
when roads are free of snow and ice. Summer tires cause less road noise, tire wear and fuel
consumption.
@ Tips
You can also use all season tires instead of
w inter t ires. Please note that in some coun­
tries where w inter tires are required, only
w inter t ires with the
& symbol may be per­
m itted.
Snow chains
Snow chains not only imp rove the dr iving in w in ­
ter ro ad conditions, b ut also the brak ing .
.,. Only install snow chains o n the front wheels .
.,. Check and cor rect the seating of the snow
c h ains after dr iv ing a few feet, if ne cessa ry . Fo l­
low the ins tructions from the m anufactu rer.
.,. Note the maximum permit ted speed when driv ­
ing with snow chains. Do not exceed 30 mp h
(SO km/h) .
Use of snow chains is o nly pe rmitted with certain
rim/tire combinations due to technical reasons .
Check with an authorized A udi dealer or author­
ized Audi Service Fac ility to see if you may use
snow chains.
Use fine-mesh snow chain s. They must not add
more t han 0.53 in (13 .5 mm) in height, includ ing
the chain lock .
You mus t remove the snow chains on roads w it h­
out snow . Otherwise, you could impai r dr iving
abi lity and damage the tires .
A WARNING
Us ing inco rrect snow chains or insta lling snow
chains incorrectly can result in loss of vehicle
control, which increases t he risk of an acc i­
dent .
358
(D Note
Snow chains can damage the rims/whee l cov ­
ers * if the c ha ins come into direct contact
with them . Remove the whee l cove rs* first.
Use coated snow chains.
(D Tips
When using snow chains, it may be usefu l to
switch on sport mode
r=> page 152.
Low-profile tires
App lies to: vehicles with low-profi le tires
Your vehicle is equipped with low-profile t ires* at
the factory. Compared to other tire/r im combina­
t ions, low-profi le tires offer a w ider t read surface
and a la rger r im diamete r with shorter tire side­
walls. This results in an agile dr iv ing style. How­
ever, i t may reduce the leve l of com fort and in ­
crease road noise whe n driving on roads in poo r
condition .
Low-p rofile ti res ca n become damaged mo re
q uickl y than st andar d tires when dr iv ing ove r
l a rge bumps, potholes, manhole covers, speed
b u mps and curbs . Therefore, it is particularly im ­
portant to maintain the correct tire pressure
r::> page 3 51.
To reduce the risk of damage to the tires and
rims, drive very caref ully on poor roads.
Check your wheels regu larly eve ry 2,000 m i
( 3 ,00 0 km) for d amage. For ex am ple, c heck for
bulges/crac ks on the tires or deformations/
c racks on the rims.
Af ter a heavy imp act o r damage, have the tires
and rims i nspected or replaced immedia tely by
an a uthorized Audi dea le r or authorized Audi
Service Facility .
Low-p rofile ti res c an wear out f aster than stand­
a rd tires.
Summer tires are not suitable fo r cold weather,
snow or black ice. If yo u are d rivi ng in these con­
d it ions, use wi nter or a ll season tires

For example: Tread wear 200 , Traction AA, Tem­
perature
A .
All passenge r ca r tires m ust conform to Federal
Safety Requirements in add ition to these grades .
Tread wear
The tread wear grade is a comparat ive rating
based on the wear rate of the t ire when tested
under cont ro lled conditions o n a specified gov ­
e rnment test course.
For example, a t ire graded
1 50 would wear one
and one ha lf
( 1 1/2) times as well on the gove rn­
men t course as a tire g raded
100.
The relative performance of t ires depends upo n
the actual conditions of their use, howeve r, and
may depart significant ly from the norm due to
va ria tions in driving ha bits, serv ice practices and
d ifferences in road cha racteristics and climate .
Traction
The traction grades, from highest to lowest, are
AA, A, B and
C. T hose grades represent the t ire's
ab ility to stop on wet pavement as meas ured un ­
de r contro lled condi tions on specified gove rn­
ment tes t sur faces of asphalt and conc re te. A tire
mar ked C may have poor traction performance

Temperature
The temperature grades are A (t he hi ghest), B ,
a nd C, represent ing the tire's resis tan ce to t he
generation o f heat and its ability to diss ipate

Wh eel s
The grade C cor responds to a level of perform ­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standa rd
No.
109 . Grades Band A represent higher levels
of pe rformance on the laboratory test wheel than
the minimum req uired by law .
A WARNING
-The tractio n grade assigned to this tire is
based on s traight-a head braking traction
t e st s, and does no t include acceler ation, co r­
n eri ng, hy dropla ning or pe ak tra ction charac­
terist ics.
A WARNING ~ -
The tempera ture grade for t his tire is estab­
lished for a tire that is properly inflated and
not overloaded . Excessive speed, underinfla ­
tion, or excessive loading, either separate ly or
i n comb inat ion, can cause heat bu ildup and
possib le tire fai lure.
A WARNING
