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. 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 poss ible on all four
wheels .
290
.,.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 Tires. If you would
like to use different tires, please
note that the tires may perform
differently even if they are the
same size ¢
,&..
.,. 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 ¢&, .
The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires 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.
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 -
son, in case of emergency, only .,.

0 a, .... N ,.... N .... g :r ..
use a spare tire* that is the same
circumference as the regular
tires.
&_ 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-
Wheels
lutely necessary and drive
carefully when doing so .
-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
Fig. 266 T ire profile: treadwear indica­
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.

This can especially have a nega­
tive effect on handling, on the
risk aquaplaning when driving
through water, when driving
through curves and when brak­ ing, which increases the risk of
an accident.

Tire Pressure Monitoring
System (AS, S8)
(D General notes
A ppl ies to: AS, 58
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
veh icle manufact urer 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
be l, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure te ll­
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
p roper tire maintenance, and it is the driver's re­
sponsib ility to ma intain correc t tire p ressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your veh icle has also bee n eq uipp ed w ith a TPM S
mal function indicator to indicate when the sys­
tem is not operat ing 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 mi nute and then remain cont inuously
illuminated . This sequence will continue upon
Wheels
subsequent vehicle start-ups as long as the mal ­
function exists .
When the malfunction indicator is illuminated ,
the sys tem may not be able to detect or signal
low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, including the
i nsta llation of replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replac ing one or
more tires or wheels on your vehicle to ensure
that the replacement or a lternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears
Applies to: A8, 58
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 269 I n strument cluste r: indicator light with messa ge
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread c ircumfer­
ence and vibration characteristics of the individu­
al tires.
If the press ure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
[I] and a message.
If only one tire is affected, the location of that
tire will be indicated.
T he tire press ures 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
