Uniform Tire Quality Gr ading
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 relative com­ parisons among tires. The UTQG
is not a safety rating and not a
guarantee that a tire will last for
a prescr ibed 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 loya lty
and dealer recommendations. Un­
der UTQG, tires are graded by the
tire manufacturers in three areas:
treadwear , traction, and tempera­
ture resistance . The UTQG in for­
mation on the tires, molded into
the sidewalls.
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 next
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,
22 4
DOT ... 2215 ...
means that the tire was produced
in the 22nd week of 201 5. The
other numbers are marketing co­
des that may o r may not be used
by the tire manufacturer . This in­
formation is used to contact con­ sumers if a tire defect requires a
recall.

on tires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility .
These facilities have the proper
knowledge and are equ ipped with
the required tools and replace­
ment parts .

chase¢
A -
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.
,& WA RNING -
-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 .

Wheels
-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 6 years old when abso­
lutely 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.

tor
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
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 quickly.
Treadwear indicator
The original tires on your vehicle have 1/16 inch (1.6 mm) high
"wear indicators" ¢fig.

running 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

have worn down to the treadwear
indicators . Replace the tires with
new ones
¢ ,1,. .
Wheel rotation
Rotating the wheels regularly is
recommended to ensure the tires
wear evenly. To rotate wheels, in­
stall the wheels 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 unidirectiona l tires, make
sure the tires are installed accord ­
ing to the running direction indi­
cated on the tire sidewall

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

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 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.

The correct tire pressure for tires
installed at the factory is listed on
a label. The label is located on the B-pillar
¢fig. 192, ¢fig. 193.
Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially loaded¢
table
on page 230 .
If driving the vehi­
cle when fully loaded, you must increase the tire pressure to the
maximum specified pressure¢.&-
228
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 labe l¢
fig. 193 for
the correct tire pressure based
on vehicle load .
.,..Correct the tire pressure if nec­
essary .
.,..Vehicles with Tire Pressure Mon­
itoring System*: store the modi­
fied tire pressure in the Infotain­ ment system ¢
page 23 7.
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 230,
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.
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 B­ pillar, always follow the specifica­
tion on the B-pillar label

'® For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption .
Audi recommends using the
tire pressure specified for a normal load
¢ table on
page 230
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
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 228,
fig. 192.
& 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.
Wheels
-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 -
including 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
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.
