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 adhesion properties.
Drive 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.

... Audi recommends that you use
Audi Original equipment tires. If
you would like to use different
tires, please note that the tires
may perform differently even if
they are the same size¢,&..

II WARNING -I
-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 6 years old when abso
lutely necessary and drive
carefully
when doing so.
258
-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.

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

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.
The Gross Axle
Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.

Downloaded from www.Manualslib.com manuals search engine The fact that there is an upper
limit
to your vehicle's Gross Vehi
c le Weight Rating
means that the
total weight of whatever is being
carried
in the vehicle is Limited.
The more passengers
in the vehi
c le or passengers who are heavier
than the standard weights as

.&_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.
Wheels
-Tires on a vehicle that has
been overloaded can fail sud
denly, including a blowout and
sudden deflation, causing

The performanc e o f lo w-a spect-ratio tires is par·
t icularly sensitive t o improper inflation pres·
sure. It is therefo re important that low aspect
ratio tires are inflated to the specified pressure
and that t h e inflation pressure is re g ula rly
chec k
ed and maintained. T ire pressure s should
be checked at least once a month and alway s

What you can do to avoid tire and rim
damage
L o w aspect ratio tires can be damaged more easi·
ly by impact with potholes, cu rbs, gull ies or

dges o n th e roa d, pa rt ic u la rly ifthe tir e is un·
d e rinflated .
In order to minim ize the occu rrence of impact
damage to the ti res of your vehicle, we recom·
mend that you observe the fo llowi ng p recau ·
tions:
- Always
maintain recommended inflation p res·
sures. Check your tire pressure every 2,000
miles (3,000 km) and add air if necessary.
- Drive carefully on
roads with potholes, deep
gullies or ridges. The impac t from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause
damage to your tires.
- Af t
er any impact, immediately inspec t your
tires o r have them inspected by the nearest au
thorize d Audi dealer. Replace a da maged t ir e as
soo n a s possib le.
- In sp e

amage and wear. Damage is not always
e a sy to
see. Damage can lead to loss of air and
un
deri n flation, which could eventually cause
tire failure. If you believe that a tire 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
deliver responsive handling, they may ride less
comfortably and make more no ise than other
choices.

Reduced performance in winter/co ld season
conditions
All ti res are designed fo r certain purposes. The
low
aspect ra tio, ultra high performance tires
originally installed on your vehicle are intended
for maximum dry and wet road performance and
handling. They are not suitable for cold, snowy or
icy weather conditions. If you drive under those
circumstances, you should equip your vehicle
with all-season
or winter tires, which offer better
tract ion under those conditions. We suggest you
use the re commended snow or all-season tires
spe cified for your vehicle, or their equiva lent.

Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width Q page 250, fig. 192.
Fo r e xample: Tread wear 200, Traction AA, Tem
perature A.
All
passenger car t ires must conform to Federal
Sa f
ety Requirements in addi tion to these grades.
Tread wear
The tread w ear grade is a comparative rating
b
ase d on the wear rate of th e tire w hen tested
u nd er c
ontro ll ed cond iti ons o n a specified go v·
ernment test course.
For ex
ample, a tire graded 150 would wear o ne
and o ne ha lf (1 1/2) times as well on the govern
ment course as a tire graded 100.
The relative performance of tires depends upon
the a ctual conditions of their use, however, and
may depart significant ly from the norm due to
varia tions in driving habits, service practices and
differences in road characteristics and cl imate.
Traction

Tempera ture
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory
test wheel.
Sustained high temperature can cause
the mate
r ial of
the tire to degenerate and reduce tire life,
and excess i
ve temperature can lead to sudden
tire failur e
c) .&..
The grade C corresponds to a leve l of perform
ance which all passenger car tires
must meet un
der
the Federal 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 assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor
nering, hydroplaning or peak traction charac
teristics.
&_WARNING
-1
The temperature grade for this tire is estab-
lished for a t
ire that is properly inflated and
not overloaded. Excessive speed, underinfla
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible t
ire failure.
&_WARNING
Temperature grades apply to tires that are
properly inflated and not over or under inflat
ed.
Wheel s
Tire pressure monitoring
system
CD General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat
ed to
the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires
of a different size than the size indicated on
the vehicle placard or tire inflation pressure la
bel, you shou ld determine
the proper tire infla
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell
tale when one or more of your tires
is significant
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them
to the proper pressure. Driving on a signifi
cantly under-inflated tire causes
the tire to over
heat and can lead to tire failure . Under-inflation
also reduces fuel efficiency 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 driver's re
spo nsibility
to maintain correct tire pressure,
even if under-inflation has
not reached the level
to trigger
illumination of the TPMS low tire pres
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys
tem is not operating properly. The TPMS mal
function
indicator 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
will continue upon
subsequent vehicle start-ups as long as the mal
function exists.
When
the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended.
TPMS malfunctions
may occur for a variety of reasons, including
the ""'

installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPM S
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more ti
res or whee ls on your veh icle to ensure
that the replacement or alternate tires and
wheels
allow the TPMS to conti nue to functi on
p roper ly .
If the Tire Pressure Monitoring System
indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or
if there is a system malfunction.
Using the ABS sensors, th e tire p ressure monitor

system compares the tire tread circumfer
ence and vibra tion char
acteristi cs of the individ u
al tires.
If the pressure changes in one or more
tires,
this i s indicated in the Infotainment system

If only one tire is affected , the location of that
tire will be ind icated.
The tire pressures must be stored in the Infotain
ment system again each time the pressu res
change (switching between partial and full load
