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.

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
formation

&_ 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 also be bro­
ken-in. To reduce the risk of losing control, a collision
and serious personal inju­
ries, drive with special care
for the first 350 miles (560 km).
-Driving with worn or dam ­
aged tires can lead to loss of
control, sudden tire failure,
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 histo­
ry." 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 vibra­tion 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 229
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.

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
all of the occupants and lug­
gage or other cargo that the ve­
h icle can carry . For the location
of the tire pressure label

Overloading a vehicle can
cause loss of vehicle control,
a crash or other accident, se­
rious personal injury, and
even death.
-Carrying more weight than
your vehicle was designed to carry will prevent the ve­
hicle from handling properly
and increase the risk of a
loss of vehicle control.
-The brakes on a vehicle that
has been overloaded may not be able to stop the vehi­
cle with in a safe distance .
-Tires on a vehicle that has been overloaded can fail
suddenly causing loss of
control and a crash.
- Always make sure that the
total load being transported
- including the weight of a
trailer hitch and the tongue
weight of a loaded trailer - does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rat­ing.

The tires and rims are essential
parts of the vehicle's design.
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 procedures and
have the necessary special tools
and spare parts as well as the
proper facilities for disposing of
the old tires.
Authorized Audi dealers have
the necessary information

about technical requirements
for installing or changing t ires
and rims.
Replacing tires and wheels
Tires should be replaced at least in pairs and not individu ­
ally (for example both front
tires or both rear tires togeth­ er) .
Be sure to read and heed the in­
formation to the tire pressure monitoring system*
¢ page 257.
Always buy replacement radial
tires that have the same specifi­
cations as the tires approved
for your vehicle by Audi. Re­
placement tires must always
have the same load rating spec­
ification as the original equip ­
ment or approved optional tires
listed in the table¢
page 234.
Audi-approved specification
tires are specially matched to
your vehicle and its load limits and can contribute to the im­
portant roadholding, driving
characteristics, and safety of
the vehicle. The table ( ¢

The tire pressure label located on driver's side B-pillar
( c::> page 234J fig. 190) lists the
specifications of the original
equipment tires installed on
your vehicle at the time it was
manufactured.
Federal law requires tire manu­
facturers to place standardized information on the sidewall of
all tires
¢fig. 193. This infor­
mation identifies and describes
the fundamental characteris­
tics, the quality grade of the
tire and also provides a tire identification number for safety
standard certification and in
case of a recall.
Tire specifications
Knowledge of tire specifications
makes it easier to choose the
correct tires. Radial tires have
the tire specifications marked on the sidewall , for example:

Maximum Permissible
Inflation Pressure
This number is the greatest
amount of air pressure that
should ever be put in the tire
under normal driving condi­
tions.
.&_ 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 sure of their "previous
histo­
ry." Old used tires may have
been damaged even though
the damage cannot be seen
that can lead to sudden tire
failure and loss of vehicle
control.
-All four wheels must be fit­ ted with radial tires of the
same type, size (rolling cir­
cumference) and the same
tread pattern. Driving with different tires reduces vehi­
cle handling and can lead to
a loss of control.
-If the spare tire is not the
same as the tires that are
mounted on the vehicle -for
example with winter tires -
only use the spare tire for a
short period of time and
drive with extra care. Refit
the normal road wheel as soon as safely possible.
-Never drive faster than the maximum speed for which
the tires on your vehicle are
rated because tires that are
driven faster than their rat­
ed speed can fail suddenly.
-Overloading tires cause heat build-up, sudden tire fail ­
ure, including a blowout
