2016 AUDI A8 wheel bolts

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

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/t ighten
easi ly.
Rims
R ims with a bolted rim ring* or with bolted wheel
covers* consist of m ultip le pieces. These compo­
n ents were bolted toge ther using specia l bolts
a nd a specia l procedu re. You must not repair or
disassemble them¢
A.
A WARNING
Wheel bolts that are t ightened or repaired in­
co rrectly can become loose and result in loss
of vehicle control, which increases the risk of
an acc ident. For the correct tightening specifi­
cation, refer to¢
page 260.
-Always keep the wheel bolts and the
threads in the whee l hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
- Always have damaged r ims repaired by an
authorized Audi dealer or authorized repair
facility. Never repair or d isassemble rims
yourself, because th is increases the r isk of
an acc ident .
Winter tires
W inte r tires s ignificantly improve the vehicle's
h andling when d rivi ng in winter condit ions. Be­
cause of the ir constr uction (width, compound,
t read pattern), summe r ti res provide less trac­
tion on ice and snow.
"'U se winte r tir es on all four wheels.
"' Only use winter t ires that a re approved for your
vehicle.
"' Please note that the maximum permitted
speed may be lower with winter tires
¢ &, .
Wh eel s
Your authorized A udi dealer or authorized re­
pair facility can inform you about the maximum
permitted speed for your tires.
"' Check the tire pressure after insta lling wheels
¢page 246.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.157 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re­ gardless of the rema ining t read .
A WARNING
'---
-Never d rive faster than the max imum pe r­
mitted speed for your tires. This could ca use
the t ires to heat up too mu ch. This in cr eases
the r isk of an accident because it can ca use
the t ire to burst.
- Always adapt your driving to the road and
traffic cond itions. Drive carefully an d reduce
your speed on icy or slippery roads. Even
winter t ires can lose tract ion on black ice.
@ For the sake of the environment
Reinsta ll summer tires a t the app ropr iate
time, beca use they prov ide bette r handling
when roads are free of snow and ice . Summer
tires cause less road noise, tire wear and fue l
consumpt ion.
(D Tips
You can also use all season tires instead of
winter tires . Please note that in some coun ­
tries where winter tires are required, on ly
winter tires w ith the
& symbo l may be per­
mitted.
Snow chains
Snow chains improve traction in the snow.
"' On ly install snow chains on the front wheels.
"' Check and co rrect the seating of the snow
chains if necessary after driving a few feet. Fol­
low the instructions from the manufacturer.
"' Note the maximum permitted speed when dr iv­
ing with snow chains. Do not exceed 30 mph
(SO km/h) . ...

Depending on the equipment, the vehicle tool kit
may be located under the spare tire under an ad­
d itional cover or in the too l box. The position of
the vehicle jack* may vary.
A WARNING
Improper use of the vehicle jack can cause se­
r ious personal injuries.
- Never use the screw driver hex head to
t ighten wheel bolts, since the bolts cannot
attain the necessary tighten ing torque if you
use the hex head, potentia lly causing an ac­
c ident.
- The factory-supplied jack is intended on ly
for your vehicle model. Under no circum­
stances should it be used to lift heavy
vehicles or other loads; yo u risk injuring
yo urself.
- Never start the engine whe n the vehicle is
raise d, which could ca use a n accident.
- Support the veh icle secure ly with appropr i­
a te stands if wor k is to be perfo rmed u nder ­
neath the veh icle; otherwise, the re is a po­
tential risk for in jury.
- Never use the jack s upplied with your Audi
on another vehicle, particularly o n a heav ier
one. The jack is only suitab le for use on the
vehicle it came wit h.
@ Tips
The vehicle j ack* in your vehicle is mainte ­
nance -free.

ques
on all wheel bolts checked with a torque
wrench. The correct tightening torque is 90 ft
lb (120 Nm).
• Have the flat tire
replaced as soon as possible.
@ Tips
- If you notice that the whee l bolts are cor­
roded and difficu lt 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.
- After changing a wheel, the tire pressure in
a ll four tires must be checked/corrected and
the tire pressure mon itor ing indicator must
be stored in the MMI

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.
