General notes
Tires may be the least appreci­
ated and most abused parts of
a motor vehicle .
Tires may be the least appreci­
ated and most abused parts of
a motor vehicle. Tires are, how­
ever, one of the most important
parts of a vehicle, particularly
considering the comparatively
small patch of rubber on each
tire that assures that all-impor­
tant contact between you, your
vehicle and the road.
Maintaining the correct tire
pressure, making sure that your
vehicle and its tires do not have
to carry more weight than they can safely handle, avoiding
damage from road hazards and
regularly inspecting tires for
damage including cuts, slashes
irregular wear and overall con­
dition are the most important
things that you can do to help avoid sudden tire failure includ­
ing tread separation and blow-
~ outs.

Avoiding damage
If you have to drive over a curb
or similar obstacle , drive very
slowly and as close as possible
at a right angle to the curb.
Always keep chemicals includ­ ing grease, oil, gasoline and
brake fluid off the tires.
Inspect the t ires regularly for
damage (cuts, cracks or blis­
ters, etc.). Remove any foreign bodies embedded in the treads.
Storing tires
Mark tires when you remove
them to indicate the direction
of rotation. This ensures you to be able to mount them correct­
ly when you reinstall them.
When removed, the wheels or
tires should be stored in a cool, dry and preferably dark place.
Store tires in a vertical position if they are not mounted on
rims, in a horizontal position if
they are mounted on rims.
New tires
New tires have to be broken in

Hidden damage
Damage to tires and rims is of­
ten not readily visible. If you notice unusua l vibration or the
vehicle pulls to one side, this may indicate that one of the
t ires has been damaged . The
tires must be checked immedi ­
ately by an authorized Audi
dealer or qualified workshop .
Unidirectional tires
A unidirectional tire can be
identified by arrows on the
sidewall, that point in the direc­
tion the tire is designed to ro­
tate. You must follow the speci­
fied direction of rotation . This is
necessary so that these tires
can develop their optimum
characteristics regarding grip,
road noise, wear and hydro­
planing resistance. For more in­
format ion
c:> page 311 .
&_ WAR NIN G
New tires or tires that are
old, worn or damaged cannot
provide maximum control
and braking ability. -
New tires tend to be slip­
pery and must be broken in .
To reduce the risk of losing
control, a collision and seri­
ous personal injuries, drive
with special care for the
first 350 miles (560 km).
-Driv ing with worn or dam­
aged tires can lead to loss of
control, sudden tire fa ilure,
including a blowout and
sudden deflation, crashes
and serious personal inju­
ries. Have worn or damaged
tires replaced immediately.
-Tires age even if they are
not being used and can fail
suddenly, especially at high
speeds . Tires that are more
than 6 years old can only be
used in an emergency and
then with special care and
at low speed .
-Never mount used tires on your vehicle if you are not
sure of their "previous histo­ry." Old used tires may have
been damaged even though
the damage cannot be seen
that can lead to sudden tire
failure and loss of vehic le
control.

-If you notice unusual vibra­
tion or if the vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so and check the
wheels and tires for dam­ age.
(D Note
-Please note that summer
and winter tires are de­
signed for the conditions
that are typical in those sea­
sons. Audi recommends us­ing winter tires during the
winter months. Low tem­ peratures significantly de­
crease the elasticity of
summer tires, which affects
traction and braking ability.
Tires and wheels 273
If summer tires are used in
very cold temperatures, cracks can form on the tread
bars, resulting in perma­
nent tire damage that can
cause loud driving noise and unbalanced tires. Audi is not
responsible for this type of
damage.
-Burnished, polished or chromed rims must not be used in winter road condi­
tions. The surface of the
rims does not have suffi­
cient corrosion protection
for this and could be perma­
nently damaged by road salt
or similar substances.

Glossary of tire and loading terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto­ matic transmission, power
steering, power brakes, power
windows, power seats, radio, and heater, to the extent that
these items are available as fac­
tory-installed equipment (whether installed or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent. Numbers of 55 or lower indi­
cate a low sidewall for im­
proved steering response and
better overall handling on dry
pavement.

wa .
The correct tire pressure for the
spare wheel is located on a la­
bel on the driver's side B-pillar.
Because technical changes may
be made to vehicle equipment
during the model year, always
compare the tire size designa­
tion on the tire pressure label on your vehicle with the tires on
your vehicle. Make sure that the tire size information on the ve­
hicle label is the same as the
size of the tires on the vehicle.
This is especially important if
the vehicle belongs to someone
else or you bought the vehicle
with different rims/tires or you
bought the vehicle as a previ­
ously owned vehicle. Remember, your safety and
that of your passengers also de­ pends on making sure that load
limits are not exceeded. Vehicle
load includes everybody and ev­
erything in and on the vehicle.
These load limits are technical- ly referred to as the vehicle's
Gross Vehicle Weight Rating ("GVWR"). The Gross Axle
Weight Rating ("GAWR") is the maximum load that can be ap­
plied at each of the vehicle's
two axles. The Gross Vehicle
Weight Rating and the Gross
Axle Weight Rating are listed on the safety compliance stick-
er label located on the driver's
side B-pillar. The tire pressure label on your Audi lists the
maximum combined weight of ""

The tires and rims approved by
Audi are specially matched to
the characteristics of the vehi­
cle and can make a major con­
tribution to good road holding and safe handling when in good
condition and properly inflated
¢ ,&..
We recommend that all work
on tires and wheels be per­
formed by an authorized Audi
dealer. They are familiar with
recommended p rocedures and
have the necessary special too ls
and spare parts as well as the proper facilities for disposing of
the old ti res.
Autho rized Audi dealers have
the necessary information
about technical requirements
for installing or changing tires
and rims .
Replacing tires and wheels
Tires sho uld be replaced at
least in pairs and not individu­
ally (for example both front
tires or both rear tires togeth­
er).
B e sure to read and heed the in ­
formation to the tire pressure
monitoring system
c::> page 301.
Always buy replacement radial
tires that have the same specifi­cations as the tires approved
for your vehicle by Audi. Re­
placeme nt tires m ust always
have the same load rating spec­
ification as the orig inal equip­
ment or approved optional tires
listed in the table c::>page

recommend using only these
tires because they meet the highest standards regarding
safety and driving characteris­
tics when used correctly. Your
authorized Audi dealer will
gladly provide you with more
information.
Tire ply composition and materials used
The number of plies indicates
the number of layers of rubber­
coated fabric in the tire. In gen­
eral, the greater the number of plies, the more weight a tire
can support. Tire manufactur­
ers also must indicate the ma­
terials in the tire, which include steel, nylon, polyester, and oth­
ers .
Maximum Load Rating
This number indicates the max­
imum load in kilograms and
pounds that can be carried by
the tire.

A WARNING
- Using incorrect or unmatch­
ed tires and/ or wheels or
improper tire and wheel
combinations can lead to
loss of control, collision and
serious personal injury.
-Always use tires, rims and wheel bolts that meet the specifications of original
factory-installed tires or
other combinations that have been specifically ap­
proved by the vehicle manu­
facturer.
-Tires age even if they are not being used and can fail
suddenly, especially at high speeds. Tires that are more
than 6 years old can only be
used in an emergency and
then with special care and at lower speeds.
-Never mount used tires on your vehicle if you are not

run flat tires. If run flat tires
are u sed , they must be in­
stalled on all four wheels. Mixing tire types is not per­
mitted.
(D Note
-For technical reasons, it is not generally possible to
use the wheel rims from
other vehicles. This can hold
true for wheels of the same
vehicle type.
- If the spare tire is different
from the tires that you have mounted on your vehicle
(for example winter tires or
wide profile tires), then use
the spare tire for a short pe­ riod of time only and drive
with extra care. Replace the
flat t ire with the tire match­
ing the others on your vehi­
cle as soon as possible.
- Never drive without the
valve stem cap. The valves
could get damaged .
@) For the sake of the environment
Dispose of old tires in accord­
ance with the local require­ ments.
