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 210, 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, traction, 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

by the tire manufacturer. This in­
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
uting to each axle its share of the
curb weight, accessory weight,
and normal occupant weight (dis ­
tr ibuted in accordance

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 .

.,,. 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¢ ,&..
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* temporarily 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.
Applies to: vehicles with all wheel drive : 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 dam­ aged by different wheel speeds.
For this reason, in case of emer­
gency, only use a spare tire* that
is the same circumference as the
regular tires .
Wheels
A WARNING
-Do not use steel rims that are
17 inches or larger. Other­
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.

Wheels
-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 al­low enough a ir 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.
l) Obey any applicable regulations in your
country.
210
-Driving qu ickly through curves,
rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer or authorized Audi Service Facili­
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 quick ly.
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
c> fig . 186. The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
The t ires have reached the mini­
mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones
c> A . "'

Ti re rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the t ires,
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 i ng to the running direction indi­
cated on the tire sidewall
¢page 231.
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, dr ive slowly and carefully to
the nearest authorized Audi deal­ er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed.

This can increase the risk of an accident because it has a nega­
tive effect on handling, driving

Wheels
Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially
loaded ¢ table
on page 213 .
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 . 188 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 220.
~check the pressure in the emer­
gency tire*/spare tire*. Always
maintain the maximum temper­
ature that is specified for the
tire.
212
& 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 214,
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.
{tfj) Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.

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-
214
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 B-pillar.
