2015 AUDI S3 wheel bolts

258 Tires an d whee ls
tires because they meet the
h ighest standards regarding
safety and driving characteris ­
tics when used correctly. Your
authorized Audi dealer w ill
g ladly provide you with more
information.
Tire ply composition and materials used
T he number of plies indicates
the number of layers of rubber­
coated fabric in the tire. In gen­
eral, the greater the number of
plies , the more weight a tire
can support . Tire manufactur­
ers also must indicate the ma­
ter ia ls in the tire, wh ich include
steel, nylon, polyester, and oth­
ers .
Maximum Load Rating
This number indicates the max­
imum load in kilograms and
pounds that can be carried by
the tire.

Maximum Permissible
Inflation Pressure
T his number is the g reatest
amount of air pressure that should ever be put in the tire
under normal driv ing condi­
tions.
A WARNING
-Using incorrect or unmatch­ ed tires and/or wheels or
improper t ire and wheel
combinations can lead to loss of control , collision and
ser ious personal injury.
-Always use tires, rims and
wheel bolts that meet the
specifications of original
factory-installed tires o r
other combinations that
have been specifically ap ­
proved by the vehicle manu­
facturer.
- Tires age even if they a re
not being used and can fail
sudden ly, especially at high
speeds. Tires that a re more
than 6 years old can on ly be
used in an eme rgency and
then with special care and
at lower speeds.
-Never mount used tires on
your vehicle if you are no t

loss of control, crashes and serious per­
sona l injuries. Have worn or damaged tires
replaced immediate ly.
- Winter tires have maximum speed rat ing
that may be lower than your veh icle's
maximum speed .
- Never drive faster than the speed for
wh ich the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your driving to the road and traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra r is ks. A l­
ways remember:
- When brak ing, an a ll-wheel d rive vehicle
hand les in the same way as a front drive
vehicle .
- Drive carefu lly and reduce your speed on
icy and slippery roads, even winter tires
canno t he lp under blac k ice condit ions.
@) For the sake of the environment
Use summe r tires when weathe r cond i­
tions perm it. They are quieter, do not wea r
as quickly and red uce f ue l cons umption.
Snow chains
Snow chains may be fitted on ly to the front
wheels, and only to certain tire sizes . Ask you r
authorized Audi dealer on which tire sizes
snow chains can be used.
I f you are going to use snow chains, then you
must install them on the front wheels at
l east.
The snow chains must h ave low-profi le links
and must not be thicker than 0 .53 inch
(13 .5 mm), including the lock.
Remove wheel ce nte r covers a nd tr im dis cs
be fore putting snow chains on yo ur vehicle
q0 . For sa fety reasons cover caps must then
be fitted over the whee l bolts. These are avai l­
ab le from authorized Audi dea lers.
A WARNING
Using the wrong snow chains for your veh i­
cle o r instal ling them incorrect ly can in­
crease the risk of loss of cont ro l leading to
se rious pe rsonal injury .
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions p rov ided by t he snow cha in
manufac turer.
- When driving with snow cha ins never
d rive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
@ Note
- Remove snow chains before dr iv ing o n
roads not covered with snow to avoid
damaging tires and wea ring the snow
chains dow n un necessa rily .
- Snow chains, which come into direc t con­
tact with the whee l rim, can scrat ch or
damage it. Therefo re, make sure that the
s now chains are s uitably covered. Check
t he pos ition of t he snow chains after
driving a few yards and correct if neces ­
sary. Follow the inst ructions from the
snow chain man ufacturer when do ing so.
@ Tips
Where snow chains are mandatory on cer ­
tain roads, th is normally a lso applies to
vehicles with a ll-wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of w heel bol ts is matched to the
f ac tory installed rims. If different rims are fit­
ted, the co rrect wheel bo lts with the right
l ength and correctly shaped bolt heads must
be used. Th is ensures that wheels are fitted
securely and that the brake system functions
correct ly . .,..

M 1.1'1 ,....,
In certain circumstances, you may not use
wheel bo lts from a different vehicle -
even if it
i s the same mode l
Q page 291.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
control, a collision and ser ious 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 t ightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose w hile d riving if greased or
o iled,
even if tightened to the spec ified
torq ue.
- Only use wheel bo lts that belong to the
rim being ins talled.
- Never use different whee ls bolts on your
vehicle .
- Always maintain the correct tightening
torque fo r the wheel bolts to reduce the
risk of a wheel loss. If the tigh teni ng 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 whee l bolts and threads
can be damaged and the wheel ca n be­
come loose .
(D Note
The specified torque for the wheel bo lts is
90 ft lb (120 Nm) w ith a tolerance of
± 7,4 ft lb(± 10 Nm). Torque whee l bolts
diagonally. After changing a wheel, the
torque must be checked as soon as possi­
b le with a torque wrench -prefe rably by an
author ized Audi dealer or qualified wo rk­
shop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires . These tires have been thorough ly
tested and been selected spec ifically for your
model for the ir superb performance, road feel
Tire s an d wheel s 263
and handling under a variety o f driving condi ­
tions. Ask your authorized A udi dealer for
more details .
T he low aspec t ratio of these tires is ind icate d
by a numera l of
55 or le ss in the tire's size
designation. The numera l represents the ratio
of the t ire's sidewa ll height in relation to its
tread width expressed in percentage.
Conven­
tiona l tires have a he ight/w idth rat io of 60 or
more .
The performance of low-a spect-ratio tire s is
particularl y sens it iv e to improper inflation
pressure. It is therefore important that low
a spect ratio tir es are inflated to the specified
pre ssure and that the inflation pr essure i s
regularly checked and ma intain ed . Tire pr es­
s ure s should be checked at lea st on ce a
month and alway s bef ore a long trip
~ page 245 , Checking tire pressure .
A Word about Low Aspect Ratio and High
Performance Ti res
Hig h pe rformance tires are des igned for bet­
ter performance and handling in warm cli­
mates. When driving in cold, snowy or icy
weather, you sho uld equ ip your vehicle w it h
four all-season or winter tires, which
offer
better traction under those condit ions. We
suggest you use the Audi recommended win­
te r or a ll-season tires specified for you r Audi.
High performance tires a lso have a lower as ­
pect ratio that aids performance and han­
dling . Driving over rough or damaged road
surfaces, as well as debr is, cu rbs and other
obstacles can cause serious damage to
whee ls, tires, vehicle body, and suspens ion
parts . B e carefu l to avo id road hazards and re­
du ce your speed , espec ia lly if your vehicle is
equipped wi th low prof ile tires .
Please a lso remember when making your se­
lection that, wh ile these tires deliver respon­
s ive handling, t hey m ay ride less comfo rtably
and make more noise than o thers . Finally,
these tires may wear more quickly than other
c h oices.

274 What do I do no w?
When removing or installing the wheel,
the rim could hit the brake rotor and dam­
age the rotor. Work carefully and have a
second person help you.
Never use the hexagonal socket in the han ­
dle of the screwdriver to loosen or t ighten
the wheel bolts.
- Pull the reversible b lade from the screw­
driver before yo u use the hexagonal
socket in the handle to turn the whee l
bo lts.
- When mounting tires with
unid irectional
tread design
make sure the tread pat­
tern is pointed the r ight way
¢page 274.
- The wheel bolts should be clea n and easy
to tu rn . Check for d irt and corrosion on
the mat ing su rfaces of both the whee l
and the h ub. Remove a ll dirt from these
su rfaces before remo unti ng the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern p ointed in
the right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a sp are tire w ith a tread pa tte rn
i nten ded for use in a specific direc tion, p lease
note t he following:
- T he direction of rotation is marked by an a r­
row on the side of the tire.
- If the spare t ire has to be installed in the in­
c orrec t direction, use the spa re tire only
tempor arily si nce the t ire will no t be able to
achieve its op timum performance character­
istics with regard to aquaplaning, noise and
wear .
- We recommend tha t you pay particular a t­
tention to this fact during wet weather and
that you adjust your speed to matc h road
condit ions. -
Replace the flat ti re with a new one and
have it insta lled on your vehicle as soo n as
possible to resto re the hand ling advantages
of a unidirectional tire.
Notes on wheel changing
Please read t he information ¢ page 254, New
tires and replacing tires and wheels
if you a re
going to use a spa re tire which is different
from the t ires on you r vehicle.
After you change a tire:
- Check the tire pre ssure on the spare imme­
diately after installation .
- Have the wheel bolt tightening torque
c hecked with a torque wrench as soon as
possible by your author ized Audi dealer or
a qualified service stat ion.
- With steel and alloy wheel r ims, the wheel
bolts a re co rrectly 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 t ightening torque .
- Replace the flat tire w ith a new one and
have it installed on your vehicle as soon as
