General notes
Tires may be the least appreciated and most abused parts
of a motor vehicle.
Tires may be the least appreciated and most abused parts of a
motor vehicle. Tires are, however, one of the most important parts
of a vehicle, particularly considering the comparative ly sma ll patch
of rubber on each tire that assures that all- important 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 regu lar ly
inspecting tires for damage inc luding cuts , slashes irregular wear
and overa ll condition are the most important things that you can do
to help avoid sudden tire failure including tread separation and
b lowouts .
Avoiding dama ge
If you have to drive over a curb or similar obstacle, drive very slow ly
and as close as possible at a right angle to the curb.
A lways keep chemica ls includ ing grease, oil, gasoline and brake
f luid off the tires.
I nspec t the tires regularly for damage (cuts, cracks or blis ters, etc.l.
Remove any foreign bodies embedded in the treads.
Storing tires
Mark tires when you remove them to indicate the direction of rota ­
tion . This ensu res you to be ab le to mount them correctly when you
reinstal l them. When removed, the wheels or tires shou
ld be stored in a coo l, dry
and preferably dark place.
St ore t ires in a vertical posit ion if they a re not mounted on rims, in
a horizontal position if they are mounted on rims.
New tire s
New tires have to be broken in~&.
The tread dep th of new tires may va ry, according to the type and
make of tire and the tread pattern.
Hidden d ama ge
Damage to tires and rims is often not readily visible. If you notice
unusua l vibration or the vehicle pul ls to one side, this may indicate
that one of the tires has been damaged . The tires must be checked
immed iately by an authorized Audi dealer or qualified workshop .
Unidire ction al tir es
A unidirectio nal tire can be iden tif ied by arrows on the s idewa ll, that
point in the direction the tire is designed to rotate. You must follow
the specified direction of ro tation . This is necessary so that these
tires can deve lop their optimum characteristics regarding grip, road
noise, wear and hydroplaning resistance . For more information

& WARNING (continued)
crashes and serious personal injuries . 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.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­
ment (whether installed or not).
Aspect ratio means the ratio of the height to the width of the tire in percent.
Numb ers of 55 or lower indicate a low sidewall for improved
steering response and better overall handling on dry pavement.
Bead
means the part of the tire that is made of steel wires, wrapped or reinforced by ply cords and that is shaped to fit the rim.
Bead separation means a breakdown of the bond between components in the bead.
Cord
means the strands forming the plies in the tire.
& WARNING (continued)
• 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 vehicle control.
• If you notice unusual vibration or if the vehicle pulls to one side
when driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage . •
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period
before the tire pressure is measured or adjusted .
Curb weight means the weight of a motor vehicle with standard equipment
including the maximum capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optional equipment.
Extra load tire
means a tire designed to operate at higher loads and at higher infla ­
tion pressures than the corresponding standard tire . Extra load tires
my be identified as "XL",
"xi", "EXTRA LOAD", or "RF" on the side ­
wall.
Gross Axle Weight Rating ("GAWR")
means the load-carrying capacity of a single axle system, measured
at the tire -ground interfaces .
Gross Vehicle Weight Rating ("GVWR"l
means the maximum total loaded weight of the vehicle.

Tire pressures are
particularly important when the vehicle is being driven at higher
speeds , and then especially when heavily loaded even within the
permissible load -carrying capacities approved for your vehicle.
T he recommended tire pressures for your Audi depend on the kind
of tires on your vehicle a nd the n umber of passengers an d/o r
amount of luggage you w ill be transporting.
On USA vehic les, the tire pressure label is located on the driver's
s id e B- pilla r. On Cana da v ehic les, the tire pressu re labe l is loca ted
either on the driver's side 8 -pillar or inside the fuel filler flap. The tire

Bear in mind that the tire pressure monitoring system can only
monitor the tire pressures you have stored. The system does not
recognize the load condition of your vehic le.
The effectiveness of the tire pressure monitoring system will be impaired if you store normal load pressures but then operate the
vehic le at its maximum load=>&. See the
illustration=>
page 317, fig. 240 for the location of the label
either on driver's side B -p illar or inside the fuel fi ller flap (color of
the actual label and exact location on the vehicle will vary slight ly).
Note that the fol lowing tab le is accurate at the time of going to
press and is subject to change . In the event of discrepanc ies, the tire
pressure label (on USA vehicles, the tire pressure label is located on
the dr iver's side B-pi llar; on Canada vehicles, the tire pressure labe l
is located either on the driver's side B-pillar or inside the fue l fi ller

The correct t ire pressure for the
spare wheel is located on a label
either on the driver's side B-pillar or inside the fuel fil ler flap. Because technica
l changes may be made to vehicle equipment
during the mode l year, always compare the tire size designation on
the tire pressure label on your vehicle with the tires on your vehic le .
Make sure that the tire size information on the vehic le label is the _.,

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
possible to see whether the radial tires used today are underinflated
just by looking at them.
Therefore, be sure to check tire pressures at least once a month and
always before going on a long trip. Make sure to take the number of
people and the amount of luggage into account when adjusting tire
pressure for a trip -even one that you would not consider to be
"long." See=>
page 321, "Tires and vehicle load limits" for more
important information.
Always use an accurate tire pressure gauge when checking and
adjusting inflation pressures . Check all of the tires and be sure not
to forget the spare tire. If the pressure in any tire is too high when
the tire is "cold," let air out of the tire slowly with the edge of the tire
gauge and keep checking the pressure until you reach the pressure
that is correct for the load (passengers and luggage) and kind of
driving you plan to do.
If the pressure in any tire is too low, note the difference between the
pressure in the cold tire and the pressure you need and add the air
that you need to reach the correct pressure for the vehicle load
(passengers and luggage) for the tires on your vehicle as listed on
the on your vehicle and in this manual and the kind of driving you
plan to do.
Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason.
Remember that the vehicle manufacturer, not the tire manufacturer,
determines the correct tire pressure for the tires on your vehicle.
It is important to check the tire pressure when the tires are cold.
• Read the required tire pressure from the tire pressure label. On
USA vehicles, the tire pressure label is located on the driver's side
8-pillar . On Canada vehicles, the tire pressure label is located either
on the driver's side 8-pillar or inside the fuel filler flap.
• Turn the valve stem cap counter-clockwise to remove it from the
tire valve.
• Place the air pressure gauge on the valve. • The
tire pressures should only be checked and adjusted when
the tires are cold. The slightly raised pressures of warm tires must
not be reduced .
• Adjust the tire pressure to the load you are carrying.
• Reinstall the valve stem cap on the valve.
When should I check the tire pressure?
The correct tire pressure is especially important at high speeds. The
pressure should therefore be checked at least once a month and
always before starting a journey. Do not forget to check the tire pres­
sure for the spare wheel =>
page 337.
When should I adjust the tire pressures?
Adjust the tire pressure to the load you are carrying. After changing
a wheel
or replacing wheels you have to adjust the tire pressures on
all wheels. In addition, you must then initialize the new tire pres­
sures in the tire pressure monitoring system=>
page 42.
& WARNING
Incorrect tire pressures and/or underinflation can lead sudden tire
failure, loss of control, collision, serious personal injury or even
death.
• When the warning symbol I appears in the instrument
cluster, stop and inspect the tires.
• Incorrect tire pressure and/or underinflation can cause
increased tire wear and can affect the handling of the vehicle and
stopping ability .
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control.
• The driver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pressure values are located on a sticker on the driver's side 8-pillar or on the inside of the fuel
filler flap. .,_

& WARNING (continu ed )
• Only when all tires on the veh icle are filled to the correct pres­
s ure , the tire pre ssure monitoring sy stem can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage. Therefore it i s es sential that the driver observe
the specified tire pre ssure values for the tires and the correct pres­
s ures for the function of the tire pressure monitoring system.
• Alway s inflate tires to the recommended and correct tire pres ­
sure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot re sulting in tread separation , sudden ti re failure and loss
of control.
• Ex cessive speed and /overloading can cause heat build -up ,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high, the tires will wear
prematurely and the vehicle will not handle well .
• If the tire is not flat and you do not have to change a wheel
immediately , drive at reduced speed to the nearest service stat ion
to che ck the tire pressure and add air as required .
0 Note
Driving without valve stem caps can cause damage to the tire
valves. To preven t this, a lways make su re t hat facto ry instal led
va lve
stem caps on a ll whee ls are securely mounted on the va lve .
'£> For the sake of the environment
Underinflated t ires will a lso increase the fuel consumption. •
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehicle and
any t ire can car ry. A vehicle that i s ove rlo aded wil l n ot hand le well and
is more difficu lt to stop . Overloading can not only lead to loss
o f ve h ic le control, but ca n also damage impor ta nt parts o f the
vehic le and can lead to sudden tire fa ilure, inc luding a blowout and
sudden defla tion that ca n cause the vehic le to cra sh .

fi g. 240 .
& WARNING
Overloading a vehicle can cause loss of vehicle control , a crash or
other accident , serious personal injury, and even death.
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the
ri sk of the loss of vehicle control.
• The brakes on a veh icle that has been overloaded may not be
able to stop the vehicle within a safe distance.
• Tires on a vehicle that has been overloaded can fail suddenly,
including a blowout and sudden deflation , 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. •
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and luggage or other things that you plan to
transport so that you can make sure that
your vehicle will not be overloaded.
Steps for Determining Correct
Load Limit
1. Locate the statement "THE COMBINED
WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard (tire infla­
tion pressure label)=>
page 317 , fig. 240.
2. Determine the combined weight of the driver and passengers that will be riding
in your vehicle.
3 . Subtract the combined weight of the
driver and passengers from
"XXX" kilo ­
grams or
"XXX" pounds shown on the
sticker=>
page 317, fig. 240.
4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the
" XXX"
amount equals 1400 lbs. and there will
be five 150 lbs. passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs. (1400-750 (5
X 150) = 650 lbs.) t,,,
