2017 AUDI A8 wheel bolts

0 a, .... N ,.... N .... g :r ..
use a spare tire* that is the same
circumference as the regular
tires.
&_ 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 six years old when abso-
Wheels
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

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.

A WARNING
Whee l bolts that a re tightened or repaired in­
co rrectly can become loose and result in loss
o f vehicle control, which increases the risk of
an acc ident. For the correct t ightening specifi­
cat io n, see¢
page 314.
- Always keep the wheel bolts and the
th reads in the whee l hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
autho rized Aud i dealer or authorized Aud i
Service Facility. Never repair or d isassemble
rims yourse lf, because this increases the risk
of an accident .
Winter tires
Winte r ti res s ignificantly improve the veh icle's
handling when d riving i n w inte r condit io n s. Be­
cause of the ir constr uction (width, compound,
t read pattern) , summe r ti res provide less trac ­
tion on ice and snow.
298
.,. Use win ter tires on a ll four wheels .
.. On ly use winter tires that are approved for yo ur
veh icle.
.,. Please note that the maximum permitted
speed may be lower with winter tires¢&_. An
author ized A udi dealer or autho rized Audi Serv ­
ice Fac ility can inform you about the maximum
permitted speed for your t ires .
.,. Check t he tire p ressure afte r insta lling wheels
¢ page 293 .
The effectiveness of wi nter tires is reduced g reat­
l y when the tread is wo rn down to a depth of
0.157 in ( 4 mm). The characte ris tic s of winter
ti res a lso decrease g rea tly as the t ire ages, re­
gard less o f the remaining t read.
_&. WARNING
- Never drive faster than the maximum pe r­
m itted speed for your tires . This could cause
the t ires to heat up too much. This increases
the risk of an accident because it can cause
the t ire to burst .
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter t ires can lose t ract io n on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropr iate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road no ise, tire wear and fuel
consumpt ion.
(i_) Tips
You can also use all season tires instead of
winter tires . Please note that in some coun­
tries where wint er tires are required, o nly
winter tires w it h t he
& symbol may be per­
mi tted.

Notes on wheel changing
P lease read the info rmation
<=> page 29 0 if you
are going to use a spare tire which is different
from t he tires on your vehicle.
Afte r you change a ti re:
- Check the tire pressure on the spare immedi ­
ately 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 lb (120 Nm).
- If you notice that the wheel bolts are corroded
and diff icult 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.
