2013 AUDI RS5 CABRIOLET wheel bolt torque

Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed r ims. If differen t rims are fit­
ted, the correct wheel bolts with the right l ength and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -eve n if it
i s the same model
¢ page 266.
_&. WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bolts and the threads in the wheel hubs clean so the
whee l bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose wh ile driving if greased or
o iled, even if tightened to the specif ied
torque .
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle .
-Always maintain the correct tighten ing
torque for the wheel bo lts 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
cl e is moving.
If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.
Q;) Note
The spec ified torque fo r the wheel bo lts is
90 ft lbs. (120 Nm) with a tolerance of
± 7,4 ft lbs.(± 10 Nm). Torque wheel bo lts

diagonally. After changing a wheel, the
torque m ust be checked as soon as possi­
ble with a torque wrench -preferably by an
a uthori zed Audi dea ler or qualified work­
shop.
Low aspect ratio tires
Your Aud i is factory -equ ipped w ith low aspect
ratio tires . These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and hand ling under a var iety o f driving cond i­
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numeral of
55 or l ess in the tire's s ize
designation. The numera l rep resents the ra tio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage . Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
T he performance of low-a spe ct- ra tio tire s is
p ar tic ul ar ly se nsi tiv e to i mprop er i nfl ation
pre ssure. It is the refo re important that low
a spect ratio t ires are inflated to the specified
pr ess ure and that th e inflation pr essur e is
r e gula rly ch ecked and maintain ed. Tir e pre s­
s ure s should b e check ed at l east once a
m onth and alwa ys befo re a long trip
¢ page 228, Checking tire pressure.
What you c an do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, g ull ies
o r ridges on the road, pa rticularly if the tire is
u nderinflated.
In orde r to minimize the occurrence of impact
damage to the tires of your vehicle, we recom ­
mend that you observe the following p reca u­
tions:
- Always ma inta in recommended inflation
pressu res. Check your tire pressure eve ry
2,000 miles (3,000 km) and add air if neces-
sary . .., •

other wa rning dev ices to alert other mo­
torists.
- Make su re that passengers wait i n a safe
pla ce away from the vehicle and well
away from the road and traff ic.
- T o help prevent the veh icle from mov ing
sudden ly and possibly slipping off the
jack, a lways fully set the parking brake
and block the whee l diagona lly opposite
the whee l being changed with the fo ld­
ing chocks or other objects. When one
front whee l is lifted off the ground, plac­
ing the Automat ic Transmiss ion in "P"
(Pa rk) w ill
not prevent the vehicle from
moving.
- Before you change a wheel, be sure the ground is level and firm . If necessary,
use a sturdy board unde r the jack.

(D Note
If you are chang ing the wheel on a steep
incline, use a rock or similar object to
b loc k the opposite wheel to prevent the
veh icle from mov ing.
Obey all laws.

Changing a wheel
When you change a wheel, follow these­
quence described below step-by-step and in
exactly that order .
l. Remove the wheel bolt caps* . For more
details see also

wheel bolt caps.
2. Loosen the wh eel bolts c>page 247.
3. Locate the p roper mounting point fo r the
ja ck a nd align the jack below that point
c>page248 .
4. Lift the car with the jack c> page 248 .

A wheel change is not comple te without the
doing the following .
• Always store the vehicle tool kit, the jack*,
and the rep laced tire in the luggage com ­
partment
c> page 124.
• As soon as possib le, have the t ightening
torque s
on all whee l bolts checked with a
torque wrench. The correct tightening tor­
que is 90 ft lbs. (120 Nm).
• Have the flat tire
re plac ed as soon as possi­
ble.
(D Tips
- If you not ice that the wheel bolts are
corroded and difficult to turn while
chang ing a tire, they should be replaced
before you check the tightening torque .

-Drive at reduced speed until you have the
tightening torques checked.
Wheels with wheel bolt caps
Applies to vehicles: with wheel bolts wit h caps
The caps must be removed first from the
wheel bolts before the bolts can be un­
screwed .

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction .
Using a replacement tire with a tread
pattern intended for use in a specific
direction
When using a re p la cemen t tir e wi th a tread
pattern inte nded for use in a speci fic dire c­
tion, please note the fo llow ing :
- T he direction of rotation is marked by a n
ar­
row on the side of the tire .
-If the r eplacement tire has to b e insta lled in
t h e inc orre ct direction, use the tire on ly
tempor arily since the t ire will no t be ab le to
a chieve i ts op timum perfo rm ance cha rac ter ­
ist ics with rega rd to aq uap laning, noise and
wea r.
- W e recommend that you pay particular a t­
tent io n to this fact du ring wet weat her and
t h at you adjust your spee d to matc h roa d
condit ions .
- Repl ace the flat tire w ith a new one and
have it installed on your veh icle as soon as
poss ible to resto re the handling advantages
of a unid irect iona l tire .
Notes on wheel changing
Please read the information 9 pag e 233, New

go ing to use a rep lacemen t tire w hich is dif­
feren t fro m th e tires on you r veh icle.
After you cha nge a t ire :
-Check the t ire pressure on the replacement
tire immediately 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 workshop .
- 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 cor­
roded and difficult to turn while changing a tire
, they should be replaced before you
