Uniform Tire Quality Grading
is a tire information system devel ­
oped by the United S tates Nat ion­
a l Highway Traffic Safety Admin­
istration (NHTSA) that is designed
to help buyers make relative com-
1 72
parisons among tires . The UTQG
is not a safety rat ing and not a
guarantee that a tire will last for
a prescribed number of miles (kilome ters) or perform in a cer­
tain way. It simply gives tire buy­
ers add it iona l information to
combine with other considera ­
tions, such as price, brand loyalty and dealer recommendations. U n­
der UTQG , tires are graded by the
tire manufacturers in three areas:
treadwear, tract ion, and tempera ­
t ure res istance. The UTQG infor­
mation on the tires , molded into

U.S. DOT Tire Identification
Number {TIN)
This is the tire's "serial number".
It beg ins with the letters "DO T"
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 fo ur numbers
represent the week and year of
manufacture. Fo r example,
DOT ... 2217 ...
means that the ti re was produced
in the 22nd week of 2017. The

New tires or wheels
Audi recommends having all work
on tires or wheels performed by an authorized 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 gripp ing properties .
Drive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires.
.,,. Only use tires with the same de­
sign, 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 Original Tires . If you would
like to use different tires, please note that the tires may perform ...

differently even if they are the
same size
c::> .,&..
~ 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
c::> ,& .
If the spare tire is different from
the regular tires installed on the
vehicle - for example, if winter
tires or wide tires are installed -
then only use the spare tire tem­ porarily 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 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 has the same circumference as
the regular tires.

A 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 ...

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
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 dea ler
or authorized Audi Service Facili-
l ) Obey any applicable regulations in your
country.
Wheels
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 d irec­
tion

or triang les on the tire sidewall
indicate the location of the tread­
wear indicators.

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
11>

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
1 50 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
Gr oss Axle Weight R ating
("GAWR") is the maximum load
that can be applied at each of the
veh icle'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 trai ler 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.

_&. WA RNIN G
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 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 Veh icle 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 .
Steps for Determining Correct
Load Limit
1 . Locate the statement "THE
COMBINED WEIGHT OF OCCU­ PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle 's placard
(tire inflation pre ssure label)
c:::> page 176, fig. 146.
2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3 . Subtra ct the combined weight
of the driver and passengers
from
"XXX" kilograms or " XXX"
pounds shown on the sticker
c:::> page 176 , fig. 146 .
4. The re sulting figure equals the
available amount of cargo and luggage load capacity. For ex­
ample, if the
"XXX" amount
equals 1400 lbs. and there will
180
be five 150 lbs. passengers in
your vehicle, the amount of available cargo and luggage load capacity is 650 lb s.
(1400-750 (5 X 150) = 650
lb s.)
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex­
ceed the available cargo and luggage load capacity calculat ­
ed in Step 4 .
6. If your vehicle will be towing a trailer, load from your trailer
will be transferred to your ve­
hicle. Con sult this manual to
determine how this reduces
the available cargo and lug­ gage load capacity of your vehi­
cle .
~check the tire sidewall
(c:::> page 167, fig. 144) to deter­
mine the designated load rating
for a specific tire.

A WARNING 1 = -
The traction grade ass igned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­ nering, hydroplaning or peak tract ion charac­
teristics.
A WARNING
The temperature grade for this t ire is estab­
lished for a t ire that is properly inflated and
no t overloaded. Excess ive speed, underinfla­
tion, or excessive loading, either separately 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
(!) General notes
Applies to: veh icles with tire pressure monitoring system
-
Each tire, including the spare (if provided),
should be checked monthly when co ld and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placa rd or
tire i nflat ion pressure label. (If your vehicle has
tires of a different s ize tha n the s ize indicated on
the veh icle placard or tire inflation pressure la­
be l, yo u sh ou ld de termine the prope r tire infla­
tion pressure for those tires).
As an added safety feature, your veh icle has been
eq uipped w ith a tire pressu re monito ring sys tem
(TPMS) that ill uminates a low tire p ress ure te ll­
tale when one or more of your tires is significan t­
l y under-inflated. Accordingly, when the low tire
p ressure tellta le illuminates, you should stop and
check yo ur tires as soon as possible, and inflate
them to the proper pressure. Driving on a s ignifi­
cantly under-i nflated tire causes the tire to over­
h eat and can lead to t ire failure . Unde r-inflation
a lso reduces fuel efficiency and t ire t read life,
Wh eel s
and may affect the vehicle 's handling an d stop ­
ping ability.
Please note tha t the TPM S is not a s ubstitute fo r
prope r ti re maintenance, a nd it is the dr iver's re­
spons ibility to maintain co rrect t ire pressure,
even if under-inflatio n has not reached the level
to t rigge r ill umination of the TPMS low t ire pres­
s ur e te lltale .
Yo ur vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not ope rating properly. The TP MS ma l­
funct ion indicator is combined with the low t ire
pressure telltale. When the system detects a
malfu nction, the telltale w ill flash for app roxi­
mately one m inute and t hen rema in continuously
illuminated . Thi s seque nce w ill cont inue upon
s u bsequent vehicle star t-ups as long as the mal­
funct ion exists.
When the malfunction indicator is illum inated,
the system may not be able to detect o r signal
l ow tire p ressure as intended. TPMS malfunct ions
may occur fo r a v arie ty of reaso ns, including the
insta llation o f replacement or al ternate tires or
whee ls on the vehicle that p revent the TPMS
from functioning proper ly . Always check the
TPMS ma lf u nction te lltale after replac ing one or
more tires or wheels on yo ur vehicle to ensure
that the rep lacement or a lt ernate tires and
wheels allow the TPMS to continue to function prope rly.

or if there is a system malfunction .
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread c ircumfer­
