2013 AUDI TT wheel torque

snow c hains are suitably cove red . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
Where snow cha ins are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory insta lled r ims . If different rims are fit­
ted, the correct wheel bo lts with the right
length and correctly shaped bolt heads must
be used. This ensures t hat 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 -even if it
i s the same model
¢ page 245.
A WARNING
Imprope rly tig htened or maintained wh eel
bolts can become loose ca using loss of
con trol, a collision and serious person al in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be p rop ­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose w hile d riving if greased or
o iled, even if tig htened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tig htening
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 213
que of t he whee l 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 lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. After changing a whee l, the tor que
must be checked as soon as possible with a
torq ue w rench -prefe rably by an au thor­
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng under a var iety of driving condi­
tions . Ask your authorized Audi dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in pe rce ntage. Conven­
t iona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
particularly sensitive to impr oper inflation
pre ssure .
It is therefore important that low
a spect ratio tire s are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 202, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.

224 What do I do now?
What should I be
aware of when
changing a tire?
General information
The following sections will provide you with
important information on how to change a
tire using the vehicle tool kit.
However, we recommend that you have a
qualified service center change the tire and
perform all work associated with changing it .
Wheels with cap-covered wheel bolts
Applies to vehicles: with cap-covered whee l bolts
The caps must be removed first from the
wheel bolts before the bolts can be un­
screwed .
Fig. 157 Wheel change: removing the wheel bolt caps
Removing
• Push the plastic clip provided with the on­
board tool kit down over the wheel bolt cap
u ntil it engages.
• Pull on the properly engaged
plastic clip to
extract the cap¢
fig. 157 .
Refitting
• Place the caps over the wheel bolts and
push them back in.
The caps are there to protect and keep the
wheel bolts clean.
Decorative wheel covers
Applies to vehicles: with decorative wheel covers
The decorative wheel covers must be removed
first to access the wheel bolts .
Fig. 158 Wheel change: removing the wheel cover
Removing
• Insert the hook prov ided with the on board
tool kit into the hole on the center hub
piece.
• Pull off the
decorative wheel cover
¢fig. 158.
Loosening and tightening the wheel
bolts
The wheel bolts must be loosened before rais­
ing the vehicle.
Fig. 159 Wheel change: loosening the wheel bolts
Loosening
• Fit the wheel bolt wrench over the wheel
bolt and push it down as far as it will go.
• Close your grip around the
end of the
wrench handle for maximum torque and
turn the wheel bolts
counter-clockwise
about one single turn in the direction of ar -
row
r:!> fig. 159. .,..

Tightening
• Fit the wh eel b olt wren ch over t he wheel
bolt and push it down as far as it will go .
• Close your gr ip aro und the
end of the
wrench handle for maximum torque and
turn each whee l bolt
cl ock wise until it sits
tight.
A WARNING
- Us ing force without control to speed the
wheel change up can cause the veh icle to
slip off the jack and cause serious pe r­
sonal inj uries.
- Do not loosen the wheel bolts more than
one turn
before you ra ise the veh icle with
the jack. -Risk of inj ury!
@ Tips
- Never t ry and use the hexagonal socket
i n the handle of the screwdriver to loos­
en o r tighten the wheel bolts .
- If a wheel bolt sits very t ight, you may
find it easie r to loosen by carefully push­
i ng down on the end of the whee l bolt
wre nch w ith
one foot only. As you do,
ho ld on to the ca r to keep yourse lf stable
and ta ke care not to slip .
Raising the vehicle
The vehicle must be li~ed with the jack first
before the wheel can be removed .

A WARNING
-You or your passengers co uld be in ju red
while changing a wheel if you do no t fo l­
low safety precautions :

(D Note
When removing or installing the wheel,
the rim could hit the bra ke rotor and dam­
age the rotor . Wor k carefully and have a
second person help you.
N ever use the hexa gonal s ocket in the ha n­
d le of the screwdriver to loosen or t ighten
the wheel bolts.
- Pull the reversib le blade from the screw­
drive r before yo u use the hexagonal
socket in t he handle to t urn the whee l
bo lts .
- When mounting tires with
unid irectional
tread design
make s ure the tread pat­
te rn is poi nte d the r ight way

-The wheel bolts should be clea n and easy
to tu rn . Ch eck for dirt and corros ion on
the mat ing su rfaces of both the whee l
a nd th e hu b. Remove a ll dir t fro m these
s ur fa ces before remo unting the wheel.
Notes on wheel change
Pl ease rea d the information ¢ page 207, New
tires and replacing tires and wheels,
i f you are
going to use a spare t ire which is different
from the tires on your ve hicle.
Afte r you change a tire:
- Check the tire pressure on the spare imme ­
diately after mounting .
- Have the wheel bolt tightening torque
che cked 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 while changing a tire that the
wheel bolt s are co rroded and diffi cult to
turn , then they should be replaced before
you check the t ightening torque.
What do I do now? 227
- 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
-
- If you are go ing to e quip your ve hicl e
wit h tires o r rims which differ from those
which were factory installed, t hen be
sure to read the information¢
page 207,
New tires and replacing tires and
wheels .
-Always sto re the tools secu rely in lug­
gage compartment. Othe rwise, in a n ac­
cident o r su dd en maneuv er they cou ld fly
forwa rd, causi ng injury to passe ngers in
the vehicle.
Tires with unidirectional tread design
Tires with unidirectional tr ead design must be
mounted with their tread pattern pointed the
right dire ction.
A u nidirectional tire can be identified by ar­
rows on the sidewall,
which point in the direc ­
tion of t he rota tion. Yo u m ust follow the
s p ecifie d direction of rot ation. This i s nece ssa ­
r y in order fo r these tires to develop t heir op­
timum character istics regard ing grip, road
no ise, wear, and hydrop la ning.
