new, original equipment tires that
were on your vehicle at the time it
was manufactured. For the loca­ tion of the label¢

fig. 147.
Most tires lose air naturally over
t ime. They can also lose some air
if you drive over a pothole or hit a
curb while parking. It is usually not possible to see whether the
radia l tires used today are under ­
inflated just by look ing at them .
T herefore, be sure to check tire
pressures at least once a month
and always before going on a long
trip. Make sure to take the num­
ber of peop le and the amount of
luggage into account when ad­
justing tire pressure for a trip -
even one that you would not con­
sider to be "long". See
¢ page 182, Tires and vehicle
load limits
for more important in­
forma tion .
Always use an accurate tire pres ­
sure gauge when checking and
adjust ing inflation pressures .
Check all o f the tires . If the pres­
sure in any tire is too h igh when
the tire is "cold", let air ou t of the
tire slowly with the edge of the
tire gauge and keep checking the
1 8 0
pressure until you reach the pres­
sure 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 co ld tire and
the pressure you need and add
the air that you need to reach the
correct pressure fo r the vehicle
load (passengers and luggage) for
the tires on yo ur vehicle as listed
on the on your veh ic le and in this
manual and the kind of driving
you plan to do .
Never exceed the ma ximum in­
flation pressure listed on the tire sidewall for any reason.
Remember that the vehicle manu­
facturer, not the tire manufactur ­
er, determines the cor rect tire
pressure for the t ires on you r ve­
hicle.
It is important to check the tire pressure when the tires are cold .
- Read the required tire pressure
from the tire pressure label lo­
cated on driver 's side B-pillar .
- Turn the va lve stem cap counter­
cl ockw ise to remove it from the
tire va lve . .,.

-Place the air pressure gauge on the valve .
- The tire pressu res should only be
checked an d adjusted when the
t ires are cold. The slig htly 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
pressu re?
The correct tire pressure is espe­
cially important at high speeds .
The pressure should therefore be
checked at least once a month
and always before starting a jour­
ney.
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 addi ­
tion, you must then initialize the
new tire pressures in the tire pres­
sure mon itoring system

A WARNING
Incorrect tire pressures and/or
underinflation can lead sudden
tire failure, loss of control, col­ lision, serio us personal injury or
even death .
-When the warning symbol
rD]
appears in the instrument
cluster, stop and inspect the
tires.
- Incorrect tire pressure and/or
underinflation can cause in­
creased tire wear and can af ­
fect the handling of the vehi­
cle and stopping ab ility.
- 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 responsib le for
the correct tire pressures for
all t ires on the vehicle . The ap ­
plicable pressure values are lo­
cated on a sticker on the driv ­
er's side B-pillar.
-Only when all tires on the ve­ hicle are filled to the correct
pressure, the tire pressure monitoring system can work
correct ly .

Tires and wheels
-The use of incorrect tire pres­sure values can lead to acci­
dents or other damage. There­
fore it is essential that the driver observe the specified
tire pressure values for the
tires and the correct pressures
for the function of the tire pressure monitoring system.
-Always inflate tires to the rec­ ommended and correct tire
pressure before driving off.
-Driving with underinflated tires bend more, letting them get too hot resulting in tread
separation, sudden tire failure
and loss of control.
-Excessive speed and/overload­
ing 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
station to check the tire pres­
sure and add air as required .

d) Note
Driving without valve stem caps
can cause damage to the tire
valves. To prevent this, always
make sure that factory instal­
led valve stem caps on all
wheels are securely mounted on the valve.
@ For the sake of the environment
Underinflated tires will also in­
crease the fuel consumption.
Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are ...

sudden deflation, causing loss
of control and a crash .
Determining correct load
limit
Use the example below to calcu ­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload­ ed .
Steps for Determining Correct
Load Limit
1 . Locate the statement "THE
COMBINED WEIGHT OF OCCU­
PANTS AND CARGO SHOULD
NEV ER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
c:::> page 176, fig. 147.
2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle .
3 . Subtract the combined weight
of the driver and passengers
from "XXX" kilograms or "XXX"
pounds shown on the sticker
c:::> page 176, fig. 147.
4 . The resulting figure equa ls the
available amount of ca rgo and
1 8 4
luggage load capacity. For ex­
ample, 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 capac ity is 650 lbs .
(1400-7 SQ (5 X 150) = 650
lbs.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehic le.
That weight may not safely ex­
ceed the available cargo and luggage load capacity calculat­
ed in Step 4 .
6. If your vehic le w ill be towing a
trailer, load from your t railer
will be transferred to yo ur vehi­
cle . Consult this manual to de­
termine how this reduces the ava ilable cargo and luggage
load capacity of your vehicle.

Tires a nd wh eels
Tire ply composition and
materials used
The number of plies indicates the
number of layers of rubber-coat­
ed fabric in the tire. In general,
the greater the number of plies,
the more weight a tire can sup­
port . Tire manufacturers also
must indicate the materials in the
tire, which include steel, nylon, polyester, and others .
Maximum Load Rating
This number indicates the maxi­
mum load in kilograms and
pounds that can be carried by the
tire .

Replacing tires or rims on
vehicles equipped with tire pressure monitoring sy stem
The wheels on your vehicle are
equipped with a sensor which
constantly monitors the air pres ­
sure inside the tire, and then
transmits this information to the
tire pressure monitoring system.
If you are go ing to replace the
wheel rims on your vehic le, make
sure the new rims also have these
sensors. The sensors must be
compatible with the tire pressure monitoring system on your vehi­
cle.
If you install rims, which do not have the sensors, or have sensors
which are not compatible, then
the tire pressure monitoring sys­
tem will not work properly . In this
case, the tire pressure monitoring
system would not be able to mon­ itor the tire pressure or warn you
if it is necessary .
-The battery inside of the tire pressure sensor has a limited
service life.

Tires and wheels
-Temperature grades apply to tires that are properly inflated and not over or underinflated.
-For technical reasons it is not always possible to use wheels
from other vehicles -in some
cases not even wheels from
the same vehicle model.
-Do not use run-flat tires on your vehicle. Using run-flat
tires can lead to vehicle dam­age or crashes.
(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 you should put different wheels and tires on your vehi­
cle (e.g. winter wheels and
tires), you must be certain
that the wheels and tires are compatible with the tire pres­
sure monitoring system. Oth­
erwise the system will register
a malfunction and a fault message will be displayed. For
more information, contact
your authorized Audi dealer.

(D Note
-When installing new tires, be careful not to damage the
valves or tire pressure moni­
toring system sensors.
-Never drive without the valve stem cap. The valves could get
damaged.
-If the sensors must be re­ placed, then the valve must
also be replaced at the same
time.
@) For the sake of the environment
Dispose of old tires in accord­
ance with the local require­
ments.
(D Tips
Tires with the identification "ROl" have been specially matched with your Audi. We
recommend using only these
tires because they meet the highest standards regarding
safety and driving characteris­
tics when used correctly. Your authorized Audi RB dealer will
gladly provide you with more information.
