comparisons among tires. The
UTQG is not a safety rating and not a guarantee that a tire will
last for a prescribed number of
miles (kilometers) or perform in a
certain way. It simply gives tire
buyers additional information to
combine with other considera ­
tions, such as price, brand loyalty
and dealer recommendations. Un ­
der UTQG, tires are graded by the
tire manufacturers in three areas:
treadwear, traction, and tempera ­

U.S. DOT Tire Identification
Number (TIN)
This is the tire's "serial number".
It begins with the letters "DOT"
and indicates that the tire meets
all federal standards. The nex t
two numbers or letters indicate
the plant where it was manufac­
tured, and the last four numbers represent the week and year of
manufacture. For example,
DOT ... 2216 ...
means that the tire was produced
in the 22nd wee k of 2016. The
other numbers are marketing co­
des that may or may not be used
2 16
by the t ire manufacturer . This in­
formation is used to contact con­
sumers if a tire defect requ ires a
recall.
Vehicle capacity weight
means the rated cargo and lug­
gage load pl us 150 lbs. (68 k ilo ­
grams) times the vehicle's desig­ na ted seating capacity .
Vehicle maximum load on the

New tires or wheels
Audi recommends having all work on tires or wheels performed by
an author ized 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.
.,.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
Wheels
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 whee l dr ive
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
circumference as the regular
tires. ,..

Wheels
&,. 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.
-Do not use run-flat tires on
your vehicle. Using them when
218
not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on the vehicle, make sure they al­low enough air circulation to
cool the brake system. If they do not, this could increase the
risk of an accident.
Tire wear/damage

tor
Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Dr iving quickly through curves,
rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer
or authorized Audi Service Facili­
ty chec k the wheel alignment if
there is unusual wear.
-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. 189 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 ¢A.
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-
~ l) Obey any applicable regulations in your 0
§ 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 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.
A 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
through curves and when brak­
ing, which increases the risk of
an accident.

,..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.

the Infotainment system
¢ page 230 .
.,.Check the pressure in the emer­
gency tire* /spare tire*. A lways
maintain the maximum temper­
ature that is specified for the
tire.
A WARNING
Always adapt the t ire 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 223,
Tires and vehicle load limits.

-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.

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 label located on the
driver's side 8-pillar
¢ page 220,
fig. 190.

A WARNING
Overloading a ve hicl e 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
i ncrease 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 -
i ncluding 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 -
224
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. Locate t he statement "THE
COMBINED WE IGH T OF OCC U­
PANTS AND CARGO SHOULD
NEV ER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
¢ page 220, fig . 190 .
2. Determine the combined
weight of the driver and pas­
sengers that will be r iding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 220, fig. 190.
4. The resu lting fig ure 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 vehic le, the amount of
available cargo and luggage load capacity is 650 lbs . .,.

an accident. For the cor rect tighten ing spec ifi­
cation, see
c:> page 238, 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 author ized Audi
Serv ice Facility. Never repair o r disassemb le
rims you rself, because th is increases the r isk
of an acc ident .
Winter tires
Winter tires signif icant ly imp rove the vehicle's
handling when dr iv ing in winter conditions. Be ­
ca use of their const ru ct io n (w idth, compou nd,
t read pat tern), summer tires provide less t rac ­
tion on ice and snow .
.,. Use winter tires on all four wheels.
.,. Onl y use winter tires that a re approved fo r yo ur
veh icle .
.,. Please note that the maximum permitted
speed may be lower with winter tires
c:> _&. . An
author ized Audi dealer or authorized A udi Serv­
ice Facility can inform you about the maximum
permit ted speed for your tires.
.,. Check the tire pressure after insta lling wheels
c=> page220 .
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.157 in (4 mm) . T he characterist ics of winter
t ir es also decrease g reatly as the tire ages, re­
gardless of t he rema in ing t read.
_& WARNING
- Never drive fas ter than the max imum pe r­
mitted speed for your tires. This could c ause
the t ires to heat up too much. This increases
the risk of an accident because it can cause
the t ire 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 t ires can lose tract ion on black ice . ..,..
