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 possible on all four
wheels.
... use tires of the same construc­
tion, size (rolling circumference)
and the same tread pattern on
all four wheels.
... Do not replace tires individually.
At least replace both tires on the
same axle at the same time .
218
.,.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.
Applies to: vehicles with all wheel drive
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
use a spare tire* that is the same ...

circumference as the regular

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.
Tire wear/damage
Fig. 191 Tire 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 .
-Have an authorized Audi dealer
or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear. ..
219

Wheels
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear
more quickly.
Treadwear indicator
The original tires on your vehicle have 1/16 inch (1 .6 mm) high
"wear indicators" ¢fig.
191 run­
ning across the tread. Marks on
the tire sidewall (for example
"TWI" or other symbols) indicate
the positions of the tread wear in­
dicators.
The tires have reached the mini ­
mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones¢ .&..
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly . To rotate the tires,
install the tires from the rear axle
on the front axle and vice versa.
This will allow the tires to have approximately the same length of
service life.
1> Obey any applicable regulations in your
country.
220
For unidirectional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢page 248.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hidden . Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage . If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed .
&_ WARNING ~ -
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.
This can especially have a nega­
tive effect on handling, on the risk aquaplaning when driving
through water, when driving .,.

through curves and when brak­ing, which increases the risk of
an accident.

once per month and also check it before every long drive .

when the tires are
cold. Do not

es when the tires are warm .

.,,.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

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
tire valves.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.
(D Tips
Audi recommends using the
tire pressure specified for a
normal load
q table on
page 223
or for a full load
when the vehicle is partially
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.
The following table lists recom­
mended tire pressures in cold
tires according to the load and
the size of the tires installed.
