2011 AUDI S8 change wheel

Remember that the vehicle manufacturer, not
the tire manufacturer, determines the correct
tire pressure for the t ires on your vehicle.
It is impor tan t to check the tire pressu re when
the t ires a re cold .
- Read the requ ired ti re p ressure from the tire
pressure label. On USA veh icles, the t ire
pressure label is located on the drive r's side
B-pi llar . On Canada vehicles, the tire pres ­
sure label is located on the driver's side B­
pillar.
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure ga uge on the valve.
- T he tire pressures sho uld only be chec ked
and adjusted when the t ires are cold. The
s li ght ly raised pressures of warm tires must
not be reduced .
- Adjust the tire pressure to the load you are
ca rrying .
- Re insta ll the va lve stem cap on the valve.
When should I ch eck the tire pressur e?
The cor rect tire pressure is espec ially impor­
tant at high speeds. The pressure should
therefo re be checked at least once a month
a nd a lways before start ing a journey. Do no t
forget to check the tire pressure for the spare
wheel
r:!> page 261 .
When should I adjust the tire pressures ?
Adjust the tire p ressure to the load you are
carry ing. Afte r changing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels . In addition, you must then
store the new tire pressures i n the tire pres­
sure monitoring system *
r:!> page 256.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire failure, loss of contro l, col lision, ser ious persona l injury
or even death.
- When the warning symbo l
[I] appears in
the instrument cluster, stop and inspect
the tires .
Tires an d wheel s 245
-Inco rrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handli ng of the vehicle and
stopping ability .
- Incorrect tire pressures and/or underin­
flation can a lso lead to sudden t ire fail­
ure, including a blowout and sudden de­
flation, caus ing loss of veh icle cont rol.
- The drive r is responsib le for the correct
tire pressures for all tires on the ve hicle.
The appli cable pressure values a re locat­
ed on a sticke r o n the dr iver's s ide B -pil­
lar.
- Onl y when all tir es on the vehicle are fil­
led to the co rrect p ressu re, the t ire pres­
sure mon itor ing* syste m can work cor­
rectly.
- Th e use of incorrect tire p ress ure v alues
can lead to a cciden ts or o ther d amage.
T herefore it is essential that the drive r
observe the specified tire press ure va lues
for the tires and the correct pressures for
the function of the t i re p ress ure monito r­
ing system*.
- Always inflate t ires to the recommended
and correct t ire pressure before dr iv ing
off.
- Driving with underinf lated tires bend
more, lett ing them get too hot resulting
in tread separation, sudden tire failure
a nd loss of cont rol.
- Excessive speed and/overloading can
cause heat build- up, sudden tire failure
a nd loss of cont rol.
- If the tire pressure is too low or too high,
the t ires will wear prematurely and the
veh icle w ill not handle well.
- If the tire is not flat and you do not have to change a wheel immediately, d rive at
red uced speed to t he nearest servic e sta­
tion to che ck the t ire p ress ure and add
air as req uired.

remain continuously illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended . TPMS
malfunct ions may occur for a variety of rea­
sons, including the installation of replace­ ment or alternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly . Always check the TPMS malfunct ion
tellta le after replacing one or more t ires or
wheels on your vehicle to ensure that the re­
placement or alternate tires and wheels allow
the TPMS to continue to function properly.

The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.

pressure label~ page 242 . Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain cond itions (such as a spor­
ty driving style, winter condit ions or un­
paved roads), the pressure monitor indi­
cator may be delayed.
- Ask your author ized Audi dealer if run­
flat tires may be used on your veh icle.
Your vehicle registration becomes invalid
if you use these tires when not permit­
ted. Damage to your vehicle or accidents
cou ld also result.
(D Tips
- The tire pressure monitoring system
stops working when there is an ESP/ABS
malfunction.
- Using snow chains may result in a system
malfunction.
- To ensure a proper TPMS function use

- The tire pressure monitoring system on
your Audi was syntonized using tires with
the "AO" or "RO" identification. We rec­
ommend using these tires.
Reset tire pressure monitoring system
App lies to vehicles: with tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset via
MMI .
.. Switch on the ignition .

Car systems contro l button > Servicing &
checks > Tire pressure monitoring > Store
tire pressures > Yes, store now.
(D Tips
Before resetting the TPMS, the current
pressures of all four tires must correspond
to the specif ied values. Adjust the tire
pressure and reset the pressure in the tire
pressure monitoring system according to
the load you are carrying~ page 242.
- Do not store the tire pressures if you are
dr iving with snow chains. Otherwise, a
system malfunction may occur.

other warning devices to alert other mo­
torists.
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed. When one
front wheel is lifted off the ground, plac­
ing the Automatic Transmission in "P"
(Park) will
not prevent the vehicle from
moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jack.
- After installing the spare wheel, make
sure that you replace the flat tire/wheel
in its storage area properly and tighten
the knurled retaining screw securely.
@ Tips
Before changing the wheel, you must acti·
vate the jacking mode, so that the auto­
matic controls for the Adaptive Air Sus­
pension do not make it more difficult to
lift the vehicle with the jack ¢

After changing a wheel
A wheel change is not complete without the
doing the following.
.. Store and secure the wheel you replaced in
the spare wheel well.
.. Replace the tools and the jack in their prop­
er location.
.. Check the
tire pressure on the spare wheel
immediately after mounting it.
.. As soon as possible, have the
tightening
torques
on all wheel bolts checked with a
torque wrench. The correct tightening tor­
que is 90
ft lb (120 Nm).
.. Have the flat tire
replaced as soon as possi­
ble .
(D Tips
-If you notice that the wheel bolts a re
corroded and difficult to turn while
changing a tire, they should be replaced
before you check the tightening torque.
- Drive at reduced speed until you have the
tightening torques checked.
