2018 AUDI A7 wheel bolts

..,Audi recommends that you use
Audi Original Tires. If you would like to use different tires, please
note that the tires may perform
differently even if they are the
same size
i=:> &, .
..,If you would like to equip your
vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service Facility before making a pur­
chase
i=:> &, .
Because the spare tire* is differ­
ent from the regular tires instal­
led on the vehicle (such as winter
tires or wide tires), only use the spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re­
placed with a regular tire as soon
as possible.
Applies to: vehicles with all wheel drive: all four wheels must be
equipped with tires that are the
same brand and have the same construction and tread pattern so
that the drive system is not dam­ aged by different wheel speeds .
~ For this reason, in case of emer-
-~ gency, only use a spare tire* that

is the same circumference as the
regular tires.
&_ WARNING
-
-Do not use steel rims that are
17 inches or larger. Other­
wise, damage to the vehicle
and an accident could result.
-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.

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/t ighten
easi ly .
Rims
Rims with a bolted rim ring* or w it h bolted whee l
covers " consist of mu ltip le pieces . These compo­
nents were bolted together using specia l bolts

and a spec ia l proced ure. Yo u must not repair or
disassemb le them
i::> &. .
A WARNING
Wheel bo lts that are tightened or repaired in­
correct ly can become loose and resu lt in loss
of vehicle contro l, wh ich increases the risk of
an accident . For the correct tighten ing spec ifi­
cation,
see ¢ page 23 7, After changing a
whe el.
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease .
- Only use wheel bolts tha t fit the rim.
- Always have damaged rims repaired by an
author ized Audi dealer or authorized A udi
Serv ice Facility . Neve r repa ir o r disassemb le
rims you rself, because this increases the risk
of an a cciden t.
Winter tires
Win ter tires significant ly imp rove the veh icle's
handling when dr iv ing in winter conditions. Be­
ca use of their construction (width, compound,
tread patte rn), s ummer ti res provide less trac­
tion on ice and snow.
.,. Use winter tires on a ll four wheels .
.,. Only use winter tires that are app roved for yo ur
vehicle .
.,. Please note that the maximum permitted
speed may be lowe r with winter
tires¢ &. in

A WARNING
Improper use of the vehicle jack can cause se­
rious pe rsonal injuries.
-Never use the screw driver hex head to
tighten wheel bolts, since the bolts cannot
attain the necessary tightening torque if yo u
use the hex head, potentially causing an ac­
cident.
-The factory-supplied jack is intended only
for your vehicle model. Under no circum­ stances shou ld it be used to lift heavy
veh icles o r othe r loads; you risk injuri ng
yourse lf .
-Never start the engine when the vehicle is
raised, which could cause an accident.
-Support the vehicle securely with appropri­
ate stands if wo rk is to be performed under­
neath the vehicle; otherwi se, there is a po­
t ential risk fo r injury .

ing devices to alert other motorists .
- Make sur e that passengers wait in a safe
place away from the vehicle and we ll away
from the road and traffic.
236
- To help prevent the vehicle from moving
suddenly and possibly s lipping off the jack,

0 00 <.,;) ' Tires with unidirectional tr ead design
Tires with unidirectional tread design must 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 t ire with a tread pattern in­
tended fo r use in a specific direction, please note
the following:
- The direction of rotat ion 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 s ince the tire will not be able to achieve its
opt imum performance character istics with re­
gard to aquaplaning, noise and wear.
- We recommend that you pay particular atten­
t ion 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
tiona l tire .
Notes on wheel changing
Please read the information ~ page 212, New
tires or wheels
if you are going to use a spare tire
which is different from the tires on your vehicle.
After you change a tire:
- Check the tire pressure on the spare tire im­
mediately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or a
qualified service station.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of 90
ft lbs (120 Nm).
- If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire ,
they should be replaced before you check the
tightening torque.
Emergency assistance
- Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble. Remount the wheel cover.
Until then , drive with extra care and at reduced
speeds.
A WARNING
- If you are going to equip your vehicle with
tires or rims which differ from those which
were factory installed, then be sure to read the information
r=> page 212, New tires or
wheels.
- Always make sure the damaged wheel or
even a flat tire and the jack and tool kit are
properly secured in the luggage compart­
ment and are not loose in the passenger
compa rtment.
- In an accident or sudden maneuver they
could fly forward, injuring anyone in the ve­
h icl e.
- Always store damaged wheel, jack and tools
securely in the luggage compartment. Oth­
erwise, in an accident or sudden maneuver
they could fly forward, causing injury to pas­
sengers in the vehicle .
