2011 AUDI S8 wheel

258 Tires and wheels
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
AUDI Original Tires which are marked
with "AO" or "RO" on the tire sidewall.
~p age 249.
- 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 .
.. Se lect in the MMI: !CAR !function button>
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.

What do I d o now ? 261
Snow chains
For technical reasons, the use of snow cha ins
o n the compact spare tire is
not permitted .
If you do have to drive with snow chains and a
front tire fails, moun t the spare wheel wi th
ti re i nste ad of a rear tire. Install the snow
chains on the rear tire and use it to replace
the defective front tire .
A WARNING
-Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
dicators.
- If the spare tire is more than 6 years old,
use it only in an emergency and with ex­
treme caution and careful driv ing.
- The spare tire is intended only for tem­
porary and short-term use. It s hould be
replaced as soon as poss ible with the
normal whee l and tire .
- After mounting the compact spare tire,
the t ire pressure must be checked as
soon as possible . T he tire pressu re of the
compact spare t ire must be
4.2 ba r; oth­
erwise, you risk having an a ccident.
- Do not dr ive faste r than
SO mph (80 km/
h). You ris k having a n accide nt.
- Avoid full-throttle acceleration, heavy
brak ing, and fast corne ring . You risk hav­

chains on the spa re tire is not permit ted .
I f it is ne cessary to drive with t ire chains,
the spare wheel must be mounte d on the
fro nt ax le in the event of a flat in a rear
tire. The newly available front whee l
must then be insta lled in place of the
rear whee l w ith the flat tire . Installing
the t ire cha in before mounting the whee l
and tire is recomme nded .

Changing a wheel
Before changing a wheel
Observe the following precautions for your
own and your passenger's safety when chang­
ing a wheel.
.,. After you experience a t ire failur e, pull the
car we ll away from mov ing traffic and try to
re ach
level ground before you stop ¢ .&,.

A WARNING
You o r your passengers could be i nju red
while changing a wheel if you do not fo l­
l ow these sa fety precaut ions:
- If you have a flat tire, move a safe dis­
tance off the road. Turn off the engine,
turn the eme rgency flashers on and use
-

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 ¢

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
