comparisons 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 a
certain way . It simply gives tire
buyers additional information to
combine with other considera ­
tions, such as price, brand loyalty and dealer recommendations. Un­
der UTQG, tires are graded by the
tire manu facturers in three areas:
treadwear, traction, and tempera ­
ture res istance. The UTQG infor­

U.S. DOT Tire Identification
Number (TIN)
T his is the tire's "seria l number" .
It beg ins with the letters "DO T"
and indicates that the tire meets
all federal s tandards. The next
two numbers o r letters indicate
the plant where it was manufac­
tured , and the last four numbers
represent the week and year of
manufactu re . For example,
DOT ... 2216 ...
means that the tire was produced
in the 22nd week of 2016 . The
other numbers are marketing co­ des that may or may not be used

by the tire man ufact urer. 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 kg)
times the vehic le's designated
seating capacity.
Vehicle maximum load on the
tire
means that load on an individual
tire that is deter mined by dist rib­

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 gripping properties.
Dr ive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires.
.,.. Use tires of the same construc­
tion, 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.

like to use different tires, please
note that the tires may perform

The spare tire* is different from the regular tires installed on the
vehicle -for example, if winter
tires or wide t ires are installed -
so only use the spare tire* tempo ­
rarily in case of emergency and
drive carefully while it is in use . It
should be replaced with a regular
tire as soon as possible.
On
all wheel drive vehicles, 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

circumference as the regular
tires .
8,_ 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.
Wheels
-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/damage

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.

..

Wheels
-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 . 197 . The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
The tires have reached the mini­ mum tread depth
l) when they
have worn down to the tread wear
indicators . Replace the tires with
new ones ¢A.
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the tires,
install the t ires 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
ing to the running direction indi­
cated on the tire sidewall
¢page 286.
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.
8_ WARNING
Tread that has worn too low or different tread depths on the
tires can reduce driving safety.

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 ..
267

Wheels
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.
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 is limited.
The more passengers in the vehi­ cle or passengers who are heavier
than the standard weights as­
sumed 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
c::> page 265,
fig. 198.
A WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
268
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 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 . ..

of an accident.
Winter tires
W inter tire s significan tly improve the vehicle 's
handling when driving in w inter condi tions. Be­
cause of the ir construction (width, compound,
tread pattern) , summe r tires p rovide less trac­
tion o n ice and snow.
.. Use w inter t ires o n all four wheels .
.. Only use w inter t ires that are approved for your
vehicle .
.. Please note that the maximum permitted
speed may be lower with winter tires
¢ & -An
a utho riz ed Aud i dea le r o r authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed fo r you r tires.
.. Check the tire pr essu re after installing whee ls
¢ page 265.
The effectiveness of winter tires is reduced great ­
ly whe n the tread is wor n down to a depth of
0 .157 in (4 mm). The character istics of winter
tires also decrease great ly as the tire ages, re­
gardless of the remaining tread.
A WARNING
- Never dr ive faste r than the maxim um per ­
mitted speed for your t ires . This cou ld cause
the tires to heat up too much. This increases
t h e risk of an a cciden t be ca use i t can c ause
t h e tire to burst.
- Always adapt yo ur driv ing to t he r oad and
t ra ffic conditions. Drive ca refully and red uce
yo ur sp eed on icy or slippery roads. Even
winte r tires can lose traction on black ice .
@ For the sake of the environment
Reinstall su mme r tir es at the approp ria te
t ime, because they provide bet ter ha ndling
when ro ads are free of snow a nd ice. S ummer
t ires cause less road noise, ti re wea r and fuel
consumption.

(D Tips
You can also use a ll season tires instea d of
winter tires . Please note that in some coun­
tries where winter tires are required, on ly
winter tires w it h the

Check with a n authorized Audi dealer or author ­
i zed Audi Service Facility to see if you may use
snow chains.
You m ust remove the snow chains on roads wi th­
out snow . Otherwise, you co uld impair driving
ability and damage the t ires .
A WARNING
Using incor rect snow chains or installing snow
cha ins incor rectly can result in loss of vehicle
control, which increases the risk of an acci­
dent .
(D Note
-Snow chains can damage the rims/wheel

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra­
tio tires. These t ires have been thoroughly tested
and been selected specifically for your model for
their supe rb performance, road feel and handling
u nder a va riety of d riving conditions. As k your au­
thor ized Audi dealer for mo re details.
The low aspect ratio of these t ires is indicated by
a numeral of
55 or l ess in the tire's size designa­
tion. The numera l rep resents the rat io of the
tire's sidewall he igh t in relat io n to its tread w idth
expressed in pe rcen tage. Conventional t ires have
a height/w idth rat io of 60 or more .
The performan ce of low -a spe ct-ratio tire s is par­
ticular ly sen sit iv e to improper inflation pre s­
s ur e. It i s therefore import ant that low a spect
ratio tire s are infl ate d to the specified pre ssure
and that the inflation pre ssure i s regularl y
c hecked and mai nta ined . Tir e pre ssure s should
b e che cked at least once a month and alw ay s
before a long tri p ¢
page 265.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more easi­
ly by impact with potholes, curbs, gullies or
ridges on the road, particularly if the t ire is un­
derinflated .
In order to minimize the occurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the follow ing precau­
tions:
- Always maintain recommended inflation pres­
sures. Check your tire pressure every 2,000
miles (3,000 km) and add a ir if necessary .
- Drive carefully on roads with potho les, deep
gul lies or ridges. The impact from driving
t h rough or ove r such obstacles can damage
you r tires. Impact w ith a curb may also cause
damage to your tires.
Wh eel s
- After any impac t, immed iate ly inspect your
tires or have them inspected by the nearest au­ thorized A udi dealer. Replace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 mi les (3,000 km)
for damage and wear. Damage is not a lways
easy to see. Damage can lead to loss of air and
underinflation, wh ic h could eventually cause
tire fa ilure . If you believe that a t ire may have
been damaged, replace the tire as soon as pos­
sible.
- These tires may wear more quickly than others.
- Please also remember that, while these tires
delive r responsive handling, they may ride less
comfortably and make mo re noise than other
choices.
Reduced pe rfo rmance in winter /cold season
conditions
All t ires are des igned for certai n purposes. The
low aspect ratio, ultra h igh performance tires
o rigi na lly installed o n your vehicle are intended
fo r m aximum d ry and wet road per formance and
handling . They are not sui table for co ld, snowy or
icy weather conditions . If you drive under those
circumstances, you should equip yo ur vehicle
with all-season or winter tires, which offer better
tract ion under those conditions. We suggest you
use the recommended snow or all-season tires
specified for your veh icle, or their equivalent.
