Wheels and Ti res
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.
(D N ote
-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
2 4 6
and b raking 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.

@ 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 materia ls
used in the tire. These include
steel, nylon, polyester and other
materials .
@ Maximum permitted load
This number indicates the maxi ­
mum load in k ilograms and
pounds that the tire can carry.

Glossary of tire and loading
terminology
Accessory weight
means the combined weight (in
excess of those standard items
which 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 a re available as fac tory-in­
stalled equipment (whet her in ­
stalled or no t).
Aspect ratio
means the rat io of the height to
the width of the tire in pe rcent.
Numbers of 55 or lower indicate a
low sidewall fo r imp roved steer­
ing response and better overa ll
handling on dry pavement .

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.
254
-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.
-Hav e 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 TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
proper 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, the tire pressure monitor ­
ing system compares the tire tread circumfer­
ence and vibration characteristics of the individu­
al tires. If the pressure changes in one or more
tires, this is indicated in the Infotainment system
disp lay with an indicator light
RR and a message.
If only one tire is affected , the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load pressure) or after changing or replacing a tire on
your vehicle ¢
page 265 . The tire pressure moni­
toring system only monitors the tire pressure you
have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢ page 256, fig.191.
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if:
- the tire pressure in one or more tires is too low.
- the tire has structural damage .
- the tire was replaced or the tire pressure was
changed and it was not stored¢
page 265.
-the spare tire* is installed.

mm (T ire Pressure Monitoring System) Tire
pressure: malfunction! See owner's manual -
If
mm appears after switching on the ignit ion or
while driving and then the indicator light
RR in
the instrument cluster also starts to blink for
about one minute and then stays on permanent­ ly, there is a system malfunction. Try to store the
correct tire pressures¢
page 265. If the indica­
tor light does turn off or turns on again after a
short period of time , drive to an authorized A udi
dealer or authorized Audi Service Facility immedi ­
ate ly to have the ma lfunction corrected.
_& WARNING
-If the tire pressure indicator appears in the
disp lay, 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 cond it ions (such as a sporty
driving style, w inter condit ions or unpaved
roads), the pressure monitor indicator may
be delayed.
- Do not use run-flat tires on your vehicle . Us­
ing them when not perm itted can lead to
vehicle damage or accidents.
(D Tips
- The tire pressure monitoring system can al­
so stop working when there is an ESC mal­
function.
- Us ing snow chains may result in a system
ma lfunction.
- The tires w ith the identification "AO"
¢
page 253 have been matched w ith your
Audi t ire pressure monitoring system. We
recommend that you use these tires.
