Tire pre ssure mon itoring
system
means a system that detects
when one or more of a vehicle's
tires are underinflated and illumi­
nates a low tire pressure warning
telltale.
Tread
means that portion of a tire that
comes into contact with the road .
Tread separation
means pulling away of the tread
from the tire carcass.
Treadwea r indicators (TWI )
means the projections within the
principal grooves designed to give
a visual indication of the degrees
of wear of the tread. See
¢ page 334, Treadwear indicator
for more information on measur­
ing tire wear .
Uniform Tire Quality Grading
is a tire information system devel­
oped by the United States Nation­
al Highway Traffic Safety Admin­
istration (NHTSA) that is designed
to help buyers make relat ive com-
Wheels
parisons among tires . The U TQG
is not a safety rating and not a
guarantee that a tire will last for
a prescribed number of miles
(kilometers) or perform in acer­
tain way . It simply gives tire buy ­
ers additional information to
combine with other considera­
tions, such as price, brand loyalty and dealer recommendatio ns. Un­
der UTQG, tires are graded by the
tire manufacturers in three areas :
treadwear, tract ion, and tempera­
ture resistance. The UTQG infor­

U.S. DOT Tire Identification
Number (TIN)
T his is the tire's "se ria l number" .
It begins with the letters "DO T"
and indicates that the tire meets all federal standards. The next
two numbers or letters indicate
the plant whe re it was manufac­
tured, and the last four numbers
represent the week and year of
manufactu re . For example,
DOT .. . 2217 ...
means that the tire was produced
in the 22nd week of 2017 . The
other numbers are marketing co­ des that may or may not be used

formation is used to contact con­ sumers if a tire defect requires a
recall.
Vehicle capacity weight
means the rated cargo and lug­
gage load plus 150 lbs. (68 kilo ­
grams) times the vehicle's desig­ nated seating capacity .
Vehicle maximum load on the
tire
means that load on an individual
tire that is determined by distrib­
uting to each axle its share of the
maximum loaded vehic le weight
and dividing by two.
Vehicle normal load on the tire
means that load on an individual
tire that is determined by distrib­

New tires or wheels
Audi recommends having all work
on t ires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
know ledge and are eq uipped with
the required too ls and rep lace­
ment parts.
... New t ires do not yet have the
optim um gripping properties.
Drive carefully and at moderate
speeds for the first 35 0 m iles
(500 km) with new tires .
... Only use tires with the same de­
sign, size ( rolling circumfer ­
ence) , and as close to t he same
tread pattern as possible on a ll
four wheels .
...
Do not replace tires individually.
At least replace bo th tires on the
same axle at the same time .
... Audi recommends that you use
Audi O riginal Tires. If you would
like to use di fferent tires, please
note that the tires may perform

.,,. If you would like to equip your
vehic le 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¢ ,&..
Because the spare tire* is differ­
ent from the regular tires instal­
led on the vehicle (such as winter
tires or wide tires), only use the spare tire* temporari ly in case of
emergency and drive carefully
while it is in use. It should be re­
placed with a regular tire as soon
as possible.
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.
A WARNING
-
-Do not use steel rims that are 17 inches or larger. Other-
Wheels
wise, damage to the vehicle
and an accident could result .
-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 abso­lutely necessary and drive
carefully when doing so.
-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
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

ty check 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
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. 267. The letters "TWI"
or tr iangles on the tire sidewall
indicate the location of the tread­
wear indicators.
The t ires have reached the mini ­
mum tread depth

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

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
..,

Wheels
vehicle's Gross Veh ic le Weig ht
R ati ng
("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
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
Gro ss Ax le W eight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles .
T he 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 -
338
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 Rat ing
are listed on the safety compli­
ance sticker labe l located on the
driver's side B-pillar.
1.8. 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 contro l and a crash.
-Always make sure that the to­ tal load being transported

Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas ­
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehic le w ill not be over load­
ed .
Steps for Determining Correct
Load Limit
1. L ocate the statement "TH E
COMBINED WEIGH T OF OCCU­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
L BS" on your vehicle's placard
(tire inflation pressure label)
¢ page 335, fig . 269 .
2. Determine the combined
weight of the driver and pas ­
sengers that w ill be riding in
your vehic le .
3. Subt ract the combined weight
of the driver and passengers
from "XXX" kilograms or "XXX"
Wheels
pounds shown on the stick­
er ¢ page 335, fig. 269 .
4. The resulting figure equals the
available amount of cargo and
luggage load capacity . For ex­
ample , if the
"XXX" amount
equa ls
1400 lbs . and there will
be five
150 l bs . passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is
650 lbs .
(1 400- 750 (5 X 1 50) = 650
lbs .)
5. Determine the comb ined
weight of luggage and cargo
being loaded on the vehicle .
T hat weight may not safely ex­
ceed the availab le cargo and
luggage load capacity calculat­
ed in Step 4 .
6 . If your vehicle will be towing a
tra iler, load from your tra iler
w ill be transferred to your ve ­
hicle. Consult this manual to
determine how this reduces
the availab le cargo and lug­
gage load capacity of your veh i­
c le .
.,. Check the tire sidewall
(¢ page 326, fig . 266) to deter ­
mine the designated load rat ing
for a specific t ire .

Wheels
The grade C corresponds to a leve l of perform ­
ance which all passenger car tires must meet un­
der the Federa l 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 ass igned to this tire is
based on straight-ahead braking traction
tests, and does not include acce le rat ion, cor­
ne ring, hydroplaning or peak traction charac­
teristics.
A WARNING
Th e temperatu re grade for this 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
in combination, can cause heat buildup and
possible tire failure.
A WARNING
-
-
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
(l) General notes
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
ve hicl e manufacturer on the vehicle placard or
tire in flatio n press ure label. ( If yo ur vehicle has
t ires of a different siz e than the size indicated on
the vehicle placard or tire inflation pressure la­
be l, you should determine the proper tire infla­
tion pressure for those t ires) .
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure te ll­
tale when one or more of your t ires is significant­
ly under-inflated. Accordingly, when the low tire
pressure tellta le illuminates, you should stop and
342
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi ­
cant ly under-inflated t ire causes the t ire to over­
heat and can lead to tire fa ilure . Under-inflation
also reduces fue l eff iciency 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 dr iver's re­
spons ibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
su re te lltale .
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating prope rly . The TPMS mal­
function indicat or 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 wi ll continue upon
s ub sequent vehicle start-ups as long as the mal­
funct ion exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
l ow tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
i nstallation of replacement or alternate tires or
wheels on the veh icle that prevent the TPMS
from functioning properly. Always check the
TPMS ma lfunction telltale after replac ing one or
more tires or wheels on you r vehicle to ens ure
that the rep lacement or alternate tires and
whee ls allow the TPMS to continue to function
properly.
