2012 AUDI R8 SPYDER wheel bolt torque

the wheel bolts. These are available from au­
thorized Audi dealers.
A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes. Always make sure to follow the in­
structions provided by the snow chain
manufacturer .
- When driving with snow chains, never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct 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.
(D Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to ve­
hicles with all-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
Tires and wheels 199
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r:!> page 221.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious personal in­
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts 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 driving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tightening
torque for the wheel 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 moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be­
come loose.
(D Note
The specified torque for the wheel bolts is
90 ft lb (120 Nm) with a tolerance of ± 7 .4
ft lb( ± 10 Nm). Torque wheel bolts diago­
nally. After changing a wheel, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author­
ized Audi dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been selected specifically for your model for their superb performance, road feel
and handling under a variety of driving

1l.
~ Close your gr ip around the end of the
wrenc h handle fo r maximum torque and
turn each whee l bolt
clockwi se u nti l it sits
t ight.
H ave the
tightening torque of the whee l bolts
checked as soon as possible with a torque
wrench. It shou ld be 120 Nm.
Chec k the
tir e pre ssure as soon as possible .
Return the vehicle tool kit to its proper place .
A WARNING

en or tighten the w heel bolts.
- If yo u have dete rm ined t hat wheel bolts
a re cor roded and difficult to t urn, the
bo lts must be rep laced befo re checking
the to rque.
- Unti l the tig hte ning torque is checked,
d rive at redu ced speeds as a precaution .
Notes on wheel change
Please read the information ¢ page 193, New
tires and replacing tires and wheels ,
if you are
going to use a spare t ire which is different
from the tires on you r veh icle.
Afte r you change a tire :
- Check the tire pressure on the spare imme­
diately after mounting.
- Have the wheel bolt t ightening torque
chec ked w ith a torq ue wrench as soon as
poss ib le by your author ized A udi dealer or a
qualified service sta tion .

What do I do now? 209
- With stee l and alloy wheel rims, the whee l
bolts are correctly tightened at a torque of
90 ft lb (120 Nm) .
- If you notice while changing a tire that the
wheel bo lts are corroded and difficu lt to
turn, then they shou ld be rep laced 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 , d riv e with e xtra care and at re­
duced speeds.
A WARNING
- If you are going to equ ip your vehicle
