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

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

This will allow the tires to have approximately the same length of
service life.
For unidirectional tires, make
sure the tires are installed accord­ ing to the running direction indi­
cated on the tire sidewall
¢ page 355.
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 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
Wheels
risk of hydroplaning when driv­
ing through deep puddles.

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

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.

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
d isassemble them
C> _&. .
_& WARNING
Wheel bolts that are tight ened 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, see
e> page 356, Finishing.
-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 yourse lf, 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 .
"'Only use winter tires that are approved for your
vehicle .
"'Please note that the maximum permitted
speed may be lower with winter tires
e> & in
General information on page 325.
An author­
ized Audi dealer or authorized Audi Service Fa­
cility can inform you about the maximum per­
mitted speed for your tires .
"'Check the tire pressure after installing wheels
¢page 335.

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 winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
@) 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 .
(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, only
winter tires with the
& symbol may be per­
mitted.
Snow chains
Snow cha ins not only improve the driving in win­
ter road conditions, but also the braking.
"'Only install snow chains on the rear 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 (SO 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 authorized Audi dealer or author­
ized Audi Service Facility to see if you may use
snow chains.
Use
fine-mesh snow chains. They must not add
more than 0 .53 in (13.S mm) in height, including
the chain lock.
You must remove the snow chains on roads with­
out snow . Otherwise, you could impair driving
ability and damage the tires .
_& WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle

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.

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.
If the tire pressure monitoring indicator
