2016 AUDI S8 brake

Wheels
use a spare tire* that is the same
circumference as the regular
tires .
A WARNING
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of an accident.
-Only use tires that are more than 6 years old when abso-
244
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage

tor
Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer or authorized repair facility

Emergency assistance
After you have loosened all wheel bolts and raised the vehicle off the ground, remove and re­
place the wheel as follows:
Removing the wheel
.,. Use the hexagonal socket in the screwdriver
handle
to completely remove the topmost
wheel bolt and set it aside on a
clean surface
.::!> fig. 223.
.,. Screw the threaded end of the alignment pin
from the tool kit hand-tight into the empty bolt
hole¢
fig. 224 1> .
.,. Then remove the other wheel bolts as described
above.
.,. Take off the wheel leaving the alignment pin in
the bolt hole ¢0 .
Putting on the spare wheel
.,. Lift the spare wheel and carefully slide it over
the alignment pin to guide it in place ¢0 .
.,. Use the hexagonal socket in the screwdriver
handle to screw in and tighten all wheel bolts
slightly .
.,. Remove the alignment pin and insert and tight­
en the remaining wheel bolt slightly like the
rest.
.,. Turn the jack handle counter-clockwise to lower
the vehicle until the jack is fully released.
.,. Use the wheel bolt wrench to tighten all wheel
bolts firmly ¢
page 260 . Tighten them cross­
wise,
from one bolt to the (approximately) op­
posite one, to keep the wheel centered.
0 Note
When removing or installing the wheel, the
rim could hit the brake rotor/ceramic brake
rotor* and damage the rotor . Work carefully
and have a second person help you.
Never use the hexagonal socket in the handle
of the screwdriver to loosen or tighten the
wheel bolts.

> A pp lies to vehicles with cer amic brake rotors*: Use a sec­
o n d alignment p in* (sto re d in th e s pare w hee l well mold ­
in g) fo r the lower hole , fol low ing the descrip tion for the
fir st a lig nme nt pin .
264
-Pull the reversible blade from the screwdriv­
er before you use the hexagonal socket in
the handle to turn the wheel bolts.
- When mounting tires with
unidirectional
tread design
make sure the tread pattern is
pointed the right way¢
page 264.
-The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design mus t be
mounted with their tread pattern pointed in the
right direction .
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire with a tread pattern in­
tended for use in a specific direction, please note
the following:
- The direction of rotation is marked by an arrow
on the side of the tire.
- If the spare tire has to be installed in the incor­
rect direction, use the spare tire only tempora­
rily since the tire will not be able to achieve its
optimum performance characteristics with re­
gard to aquaplaning, noise and wear.
- We recommend that you pay particular atten ­
tion to this fact during wet weather and that
you adjust your speed to match road condi­ tions.
- Replace the flat tire with a new one and have it
installed on your vehicle as soon as possible to
restore the handling advantages of a unidirec­
tional tire.
Notes on wheel changing
Please read the information¢ page 243 if you
are going to use a spare tire which is different
from the tires on your vehicle.
