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 adhesion 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.
... 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 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

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 drive vehicles, all
four wheels must be equipped
with tires that are the same brand

II WARNING -I
-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
lutely necessary and drive
carefully
when doing so.
258
-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
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.

-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
Original equipment tires contain
treadwear indicators in the tread
pattern, which are bars that are
1/16 in (1.6 mm) high and are
spaced evenly around the tire per
pendicular to the running direc
tion¢ fig. 193. The letters "TWI"
or triangles on the tire sidewall
indicate the location of the tread
wea r indicators.
The tires have reached the mini
mum tread depth l) when they
have worn down to the tread wear
indicators. Replace the tires with
new ones ¢ .&.
Wheel rotation
Rotating the wheels regularly is
recommended to ensure the tires
wear evenly. To rotate wheels, in
stall the wheels from the rear
axle on the front ax le and vice
versa. This will allow the tires to
~ l) Obey any applicable regulations in your

cated on the tire sidewall

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
