2015 AUDI TT ROADSTER wheel bolt 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 227.
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 driving 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 197
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 186, 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 ..,.

Tightening
.. Fit the wheel bol t wrench over the wheel
bolt and push it down as far as it will go .
.. Close your grip around the
end of the

turn each wheel bolt
cl ock wis e unt il it sits
t ight .
A WARNING
-Us ing fo rce without control to speed the
wheel change up can cause the veh icle to
slip off the jack and ca use se rious pe r­
sonal in juries.
-Do not loosen the wheel bolts more than
one turn
before you ra ise the veh icle with
the jack. -Risk of inj ury!
(1) Tips
- N ever t ry and use the hexagona l socket
i n the handle of the screwdriver to loos­
en or tighte n the wheel bolts .
- If a whee l bolt sits very t ight, you may
find i t easie r to loosen by carefully p ush­
i ng down on the end of the whee l bolt
wrench with
one foot only . As you do,
ho ld on to the car to keep yourse lf stable
and ta ke care not to slip .
Raising the vehicle
The vehicle must be lifted with the jack first
before the wheel can be removed .

(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

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

s ur fa ces before remo unting the wheel.
Notes on wheel change
Pl ease rea d the information ¢ page 191, 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? 211
- 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 191,
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 charac ter istics regard ing grip, road
no ise, wear, and hydrop la ning.
