8,_ 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.
Wheels
-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.

Checking/correcting tire
pressure
.,,.Check the tire pressure at least
once per month and also check it before every long drive .

es when the tires are warm .

the correct tire pressure based on vehicle load.

essary.
... Store the new tire pressure in
the Infotainment system
¢page 231, ¢page 233 .
.,,.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.
-Overloading can lead to loss of vehicle control and increase
the risk of an accident. Read
221
Wheels
and follow the important safe
ty precautions in
q page 224,
Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con
trol.
-Incorrect tire pressure in
creases tire wear and has a
negative effect on driving and

(D Note
Replace lost valve caps to re
duce the risk of damage to the

@ For the sake of the environment
Tire pressure that is too low in
creases fuel consumption.
(D Tips
Audi recommends using the

loaded.
Make sure that the tire designa
tion on your tire matches the des
ignation on the tire pressure label
and the tire pressure table.

mended tire pressures in cold

A WARNING
Please note the important safe
ty precautions regarding tire pressure ¢
page 221 and load
limits¢
page 224.
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
224
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
erybody and everything in and on
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
