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.
A 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-

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.

-Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease .
- Only use wheel bo lts that fit the r im .
- Always have damaged rims repa ired by an
autho rized Aud i dealer or authorized repair
facility. Never repair or disassemble rims
you rself, because this increases the risk of
an acciden t.
Winter tires
Winte r tires sign ificantly improve the ve hicle's
handling when d riving i n w inte r condit io ns. Be­
cause of the ir constr uction (wid th, compo und,

on ice and snow .
.,. Use w inte r tir es on all fou r wheels.

.,. On ly use winter tires that are approved fo r yo ur
vehicle.
.,. Please note that t he maxim um permitted
speed may be lower with winter tires ¢

ti res a lso de crease grea tly as the t ire ages, re­
gardless of the remaining tre ad.
A WARNING
-
- Never drive faster than the max imum pe r­
m itted speed for your tires. This co uld cause
the t ires to heat up too much . This increases
the risk of an accident because it can cause
the t ire to burst.
- Always adapt your dr iving to the road and
traffic cond itions. D rive carefully and reduce
your speed on icy or slippe ry roads. Even
win ter t ires ca n lose traction on black ice.
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, beca use they provide better handling
when roads are free of snow and ice . Summer
tires cause less road noise, tire wear and fuel
consum ptio n.
(D Tips
You can a lso use all season tires instead of
winter tires. Please note that in some coun ­
tries where w inter t ires a re requir ed, only win ­
ter tires w ith the£ symbol may b e permit­
ted.

.. Use the wheel bolt wrench to tighten all wheel
bolts firmly
c;, page 256. Tighten them cross­
wise,
from one bolt to the (approximate ly) op­
posite one, to keep the whee l centered.
(D Note
When removing or installing the wheel, the
rim could hit the brake roto r 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 screwdriver to loosen or tighten the
whee l bolts.
- Pull the reversible blade from the screwdriv ­
er before you use the hexagonal socket in
the handle to turn the whee l bolts.
- When mount ing tires w ith
unidirectional
tread design
make sure the tread pattern is
pointed the right way
c;, page 259.
-The wheel bolts should be clean and easy to
turn. 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 .
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tir e with a tread pattern in­
tended for use in a specific direction, please note
the following:
- The direction of rotation is marked by an arrow
on the side of the tire . .,.
259

Emergency assistance
-If the spare tire has to be installed in the incor­
rect direction, use the spare tire only tempora­
rily s ince the tire will not be able to achieve its
optimum performance characteristics with re­ gard to aquaplaning, noise and wear.
- We recommend that you pay particular atten­
tion to this 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 vehicle as soon as possible to
restore the handling advantages of a unid irec­
tiona l tire .
Notes on wheel changing
Please read the information r=:> page 240, New
tires or wheels
if you are going to use a spa re tire
which is diffe rent from the tires on your vehicle.
After you change a tire:
-Check the tire pressure on the spare immedi­
ately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or a
qualified service station.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of 90
ft lb (120 Nm).
- If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire,
they should be replaced before you check the
tightening torque.
- Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble. Remount the wheel cover .
Until then, drive with extra care and at reduced
speeds .
.8, WARNING
-If you are going to equip your vehicle with
tires or rims which differ from those which
were factory installed, then be sure to read
the information
