Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap
proach the curb at an angle.
.,.Have faulty tires or rims re
placed
immediately.
.,.Protect your tires from oil,
grease and fuel.
.,.Mark tires before removing
them so that the same running
direction can
be maintained if
they are reinstalled .
... Lay tires flat when storing and
store them in a cool, dry location
with
as little exposure to light as
possible.
CD Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom
mends using winter tires dur
ing the winter months. Low
temperatures significantly de
crease the elasticity of summ
er tires, which affects traction
250
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi
tions. The surface of the rims
does not have sufficient corro
sion
protection for this and
could be permanently dam
aged by road salt or similar
substances.

be happy to provide more infor
mation.
® Mud and snow capability
"M/S" or "M+S" indicates the tire
has characteristics that make it
suitable for driving on mud and
snow. & indicates a winter t ire.
@ Compos ition of the tire cord
and materials
The number of plies indicates the
number of rubberized fabric lay
ers in the tire. In general: the
more layers, the more weight a
tire can carry. Tire manufacturers
must also specify the materials
used in the tire. These include
steel, nylon, polyester and other
materials.
@Maximum permitted load
This number indicates the maxi
mum load in kilograms and
pounds that the tire can carry.
@Uniform tire quality grade
standards for treadwear,
traction and temperature
resistance

ature ranges c:> page 266.

@ Running direction
~ Maximum permitted
inflation pressure
This number indicates the maxi
mum pressure to which a tire can
be inflated under normal operat
ing conditions.
Glossary of tire and loading
terminology
Accessory weight
means the combined weight (in
excess of those standard items
wh ich may be replaced) of auto
matic transmission, power steer
ing , power brakes, power win
dows, power seats, radio , and
heater, to the extent that these
items are available as factory-in
stalled equipment (whether in
stalled or no t).
Aspect ratio
means the ratio of the height to
the width of the tire in percent.
Numbers of SS o r lower indicate a
low
sidewall for improved steer
ing response and better overa ll
handling on dry pavement.
Bead
means the part of the tire that is
made of steel wires, wrapped or ...

circumference as the regular
tires.
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.
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.
-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.

installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPM S

TPMS malfunction telltale after replacing one or
more ti

that the replacement or alternate tires and
wheels
allow the TPMS to conti nue to functi on

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
i n g
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
d isp lay
with an ind icator light RI and a message .
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
pressure) or
after changing or replacing a tire on
your veh icle ¢ page 269. The tire pressure moni
toring system only monitors the tire pressure you
have stored. Refe r
to the tire pressure label for
the recommended tire pressure for your veh icl e
¢page260, fig.195.
Tire tread circumference and vibration character

-
the tire p ressure in one or more tires is too low.
-
the tire has structural damage .

.&. WARNING
-If the tire pressure indicator appears in the
display, reduce your speed immediately and
avoid any hard steering or brak ing maneu
vers.
Stop as soon as poss ible and check the
tires and
their pressure .
- The driver is responsible
for maintain ing the
correct tire pressures . You must check the
tire pressures regularly .
-
Under certain condit ions (such as a sporty
driving style, wi
nter condit ions or unpaved
roads), the pressure

be delayed.
-
Do not use run-flat tires on your vehicle . Us
ing them when not perm itted can lead to
veh icle damage or accidents.

is an ESC mal
func tion.
-
