2013 AUDI A8 torque

26 6 T ire s and whee ls
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging t ires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into d irect con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
- If the Adaptive Air Suspension should
malfunction, do not mo unt or use snow
cha ins beca use the veh icle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severely dam­
age the wheelhouse and other parts of
the veh icle.
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
veh icles with All Wheel Drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts with the r ight
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
cor rectly .
In certain circumstances, you may not use
wheel bolts from a different vehicle - even if it is the same model
~ page 298.
A WARNING
Imprope rly tightened o r maintained wheel
bolts can be come loose caus ing loss of control, a col
lision and serio us personal in­
jury.
- Always keep the wheel bo lts and the
threads in the whee l hubs clean so the
wheel bo lts can turn easily and be prop­
erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can become loose while driv ing if greased or
oiled, even if t ightened to the specified
torque.
- Only use wheel bolts that belong to the rim being installed .
- Never use different wheels bolts on your
veh icle.
- Always ma intain the correct tightening
torque for the whee l bolts to reduce the
risk of a wheel loss. If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be ­
come loose .
(D Note
The specified torque for the whee l bolts is
90
ft l b (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm) . Torque whee l bolts diago ­
nally . After changing a whee l, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author­
i zed Audi dealer or qualif ied workshop.
Low aspect ratio tires
Your Audi is factory-equ ipped w ith low aspect
ratio tires . These tires have been thoroughly
tested and been se lected specifically fo r your
model for their superb perfo rman ce, road fee l
and hand ling under a variety o f driving condi­
tions. Ask your authorized A udi dealer for
more details .
T he low aspect ratio of these tires is ind icated
by a numera l of
55 o r less in the tire's s ize
designation. The numeral rep resents the ratio
of the tire's sidewa ll height in relation to its
ll-

After changing a wheel
A wheel change is not complete without the
doing the following .
.,. Always store the vehicle tool kit, the jack*
and the rep laced tire in the luggage com­
pa rtment
¢ page 140.
... Check the tir e pr essure on the spa re whee l
immed iate ly afte r mounting i t.
.,. As soon as possib le, have the
tightening
torques
on all whee l bolts che cked with a
torque wre nch. The correc t tig hten ing tor ­
que is 90 ft l b (120 Nm).
... Have the flat tire
replaced as soon as possi ­
ble.
@ Tips
- If you not ice that the w heel bo lts a re
co rroded and difficult to turn while
chang ing a tire, t hey shou ld be rep laced
before you check the tig htening to rque.
- Dr ive at reduced speed until you have the
t ightening torques checked.
- After changing a whee l, the t ire p ress ure
in all four tires must be chec ked/co rrect ­
ed and the tire p ress ure monito ring in di­
cator must b e sto red in th e MMI

su rfaces before remo unt ing the wheel.
Tires with unidirectional tread 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 spa re tire with a t read patte rn
i n te nded fo r use in a specific direction, please
note the fo llowing:
- T he direction o f rotation is marked by a n ar­
row on the side of the tire.
- If the spare t ire has to be in stalled i n the in ­
corre ct d irection, use the sp are tire on ly
temporarily since the t ire will not be a ble to
achieve its optimum perfo rmance character­
ist ics with rega rd t o aquaplaning, noise and
wea r.
- We recommend t hat you pay pa rticular at­
tent ion to this fact during wet weat her and
t h at y ou adjust your speed to matc h road
condit ions .
- Replace the flat tire w ith a new one and
have it installed o n your ve hicle as soon as
poss ible to restore th e handli ng a dvantages
of a un id irect iona l tir e.
Notes on wheel changing
Pl ease re ad the informa tion i:> page 260, New
t ires and repl acing tires and wheels
if you are
goin g to use a spare tire which is differen t
from the tires on your ve hicle.
Afte r you cha nge a tire :
-Check the t ire pressure on the spare imme ­
diately after installation .
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as
possible 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 cor­
roded and difficult to turn while changing
a tire , they should be replaced before you
check the tightening torque.
- Replace the flat tire with a new one and
have it installed on your vehicle as soon as
possible. Remount the wheel cover .
Until then , drive with extra care and at re­
duced speeds.
A WARNING
- I f you are going to eq uip your vehicle
wit h tires or rims which differ from those
which were factory installed, then be sur e to r ead the information
i:> page 260,
