New tires or wheels
Audi recommends having all work on tires or wheels performed by
an authorized Audi dea ler or au ­
thorized Audi Service Facility.
These facilities have the proper knowledge and are equ ipped with
the required tools and replace­
ment parts .
.,,. New tires do not yet have the
opt imum adhesion properties .
Drive carefully and at moderate
speeds for the first 350 m iles
(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 .
Tires a nd whe els
.,,. 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 different ly even if
they are the same size
c:::> ,& .
.,,. 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
c:::> ..1,. .
The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
then only use the spare tire* tem­
porarily 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 d riv e 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
22 1

Tires and wheels
different tire speeds. For this rea­
son, in case of emergency, only
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 6 years old when abso-
222
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

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.

The correct tire pressure for tires
mounted in the factory and for
the spare tire* is indicated on a la­ bel. The label is located on the B­
pillar
¢fig. 170, r=:>fig. 171.
When the vehicle is partially load­ed (up to 3 people), use the tire pressure specified for normal
224
loads c:> table on page 226. If
driving the vehicle when fully loaded, you must increase the tire
pressure to the maximum speci­
fied pressure ¢&, .
Checking/correcting tire
pressure
•Check the tire pressure at least
once per month and also check it before every long drive.
•Always check the tire pressure
when the tires are
cold. Do not
reduce the pressure if it increas­
es when the tires are warm.
•Check the label ¢
fig. 171 for
the correct tire pressure based
on vehicle load.
•Correct the tire pressure if nec­
essary .
•Vehicles with Tire Pressure Moni­
toring System*: store the modi­
fied tire pressure in the Infotain­
ment system ¢
page 234.
•Check the pressure in the emer ­
gency tire*/spare tire*. Always
maintain the maximum temper­
ature that is specified for the
tire.
A WARNING
Always adapt the tire pressure
to your driving style and vehicle load. .,.

Tires and wheels
The grade C corresponds to a level 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 pe rformance 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.
A WARNING
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separate ly or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat ­
ed .
Tire pressure monitoring
system
CD General notes
Applies to veh icles: w ith tire pressure monitoring system
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 should 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
232
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
sponsibility 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 t ire
pressure tel ltale. 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 ma l­
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 TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more t ires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly .

one or more tires is too low . Reduce the ve­
h icle speed immediate ly and avoid any hard
steer ing or braking maneuvers. Stop as soon
as poss ible, check the tire and inf late the
tire to the correct pressure, which is speci­
fied on the t ire p ress ure label on the vehicle
r::;, page 224. Driv ing with a tire with Low
p ressu re causes the tire to overhea t and c an
resul t in fa il ur e of the tire . Low pressure can
a lso have a negative effect on the driving
and b rak ing behavior of t he vehicle .
- T he drive r is respons ib le for main taining the
correct ti re press ures . You must check the
tire pressures regu larly .
- Under certain conditions (such as a sporty
driving style, winter conditions or unpaved
roads), the pressure monitor indicator may
be de layed.
- Do not use run-flat tires on yo ur vehicle . Us­
ing them when not permitted can lead to
veh icle damage or acc idents.

When removing or installing the wheel, the
r im could hit the brake rotor and damage the
rotor. Work carefully and have a second per­
son help you.
@ Tips
Never use the hexagonal socket in the handle
of the screwdr iver to loosen or tighten the
wheel bolts.
- Pull the reversible blade from the screwdriv­
er before you use the hexagonal socket in
the handle to turn the wheel bolts.
Emergency assistance
-When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way¢
page 245 .
-The wheel bolts shou ld be clean and easy to
t ur n. Check for dirt and corrosion on the
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction .
U sing a spare tire with a tread pattern
intended for use in a specific direction
When using a spare t ire with a tread pattern in­
tended for use in a specific direction, please note
the following:
- The direct ion of rotation is marked by an arrow
on the side of the tire.
- If the spare tire has to be insta lled in the incor­
rect direction, use the spare tire only tempora­
r ily since the tire w ill not be able to achieve its
optimum performance characteristics with re­
gard to aquaplaning, noise and wear .
- We recommend that you pay part icular atten­
tion to th is fact during wet weather and that
you adjust your speed to match road condi­
tions.
- Replace the flat tire with a new one and have it
installed on your veh icle as soon as possible to
restore the handling advantages of a unidirec­
tional tire.
Notes on wheel changing
Please read the information ¢ page 221 if you
are going to use a spare tire which is different
from the tires on your vehicle.
After yo u change a tire:
-Check the tire pressure on the spare immedi-
ately after installation.
