2014 AUDI TT ROADSTER wheel torque

198 Tire s and wheel s
snow cha ins a re suitab ly covered. Check
the position of the snow chains after driving a few yards and correct if neces ­
sary. Follow the instr uctions from the
snow cha in manufacturer when doing so.
{O) Tips
Where snow cha ins are mandatory oncer­
tain roads, this norma lly also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correc t torque .
The design of whee l bolts is matched to the
factory installed r ims . If different rims are fit ­
ted, the correct wheel bolt s with the r ight
length and correctly shaped bol t heads mus t
be used . This ensures that wheel s are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a d iffe rent vehicle -even if it
i s the same model
Q page 228.
A WARNING
Imprope rly tig htened o r maintained whee l
bolts can be come loose ca using loss of
cont ro l, a co llision and serious person al in­
jury .
- Always keep the w heel bol ts and the
t h reads in t he wheel hubs clean so the
wheel bolts can t urn easily and be p rop ­
er ly t ightened .
- N ever grease or oil the wheel bo lt s an d
the threads in the wheel h ubs. They can
become loose w hile d riving if greased or
oi led, even if tightened to the specif ied
torque.
- Only use whee l bolts that be long to the
rim being installed.
- Never use different whee ls bolts on your
vehicle .
- Always mai ntai n the co rrect tighte ning
torq ue for the wheel bolts to reduce the
risk of a wheel loss. If the tightening tor- que of the whee
l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig hte ning torq ue is
too high, the w heel bolts a nd threads
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for t he whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torque whee l bolts diago­
nally . After changing a whee l, the to rq ue
must be checked as soon as possible with a
torque w rench - prefe rably by an author­
iz ed A udi dealer or quali fied workshop .
Low aspect ratio tires
Your Audi is factory-eq uipped w ith low aspect
ratio tires. These tires have b een tho ro ughly
tested and been se lected specifically for your
model for their supe rb performance, road fee l
and hand ling under a variety of driving condi­
t ions . Ask your author ized Audi dealer for
more de tails .
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 numera l rep resents the ratio
of the tire 's s idewa ll height in relation to its
t read width exp ressed in percentage. Conven­
tiona l tire s have a he igh t/w idth rat io of 60 or
more.
The p erformance of low-a spect-ratio tire s is
particularly sensitiv e to improper inflation
pre ssure. It i s ther efore important that low
aspect ratio tires are inflated to the specified
pre ssure and that the inflation pre ssure i s
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always before a long trip
Q page 187, Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith po tholes, curbs, gul lies ..,.

210 What do I do now?
• 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
¢ fig. 156.
Tightening
• 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 each wheel bolt
clockwise until it sits
t ight.
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 per­
sonal inju ries.
-Do not loosen the wheel bolts more than
one turn
before you raise the vehicle with
the jack. -Risk of injury!
- Never t ry and use the hexagonal socket
in the handle of the screwdriver to loos­
en or tighten the wheel bolts.
- If a wheel bolt sits very t ight, you may
find i t eas ier to loosen by carefully push­
i ng down on the end of the whee l bolt
wrench with
one foot only. As yo u do,
hold on to the car to keep yourself stable
and take care not to slip .
Raising the vehicle
The vehicle must be lifted with the jack first
before the wheel con be removed .

• Apply the parking brake firmly to prevent
your veh icle from roll ing unintentionally.
• Move the
selector lever to position P .
• Position the jack be low the door sill under
t he
mounting point that is closest to the
wheel to be changed ¢
fig. 157.
• Extend the jack under the lifti ng point on
the door s ill until its arm is positioned di­
rectly under the lifting point ¢,&. .
• Align the jack so that its arm®¢
fig. 158
engages in the designated lifting point in
the door s ill and the movable base ® lies
flat on the ground . The base @ must be
ver­
tical
under the lifting point@.
• Wind the jack up further unti l the flat tire
comes off the ground ¢
.&,.
Position the vehicle jack only under the desig­
nated lifting points on the sill
¢fig . 157.
T he re is exactly one locat ion for eac h wheel.
T he jack must not be positioned at any other
location ¢
.&,¢(D .
An unstable surface under the jack can cause
the vehicle to slip off the jack. Always provide
a firm
base for the jack on the ground. If nec­
essary p lace a sturdy board or simi lar support
under the jack. On
hard, slippery surfaces
(such as tiles) use a rubber mat or similar to
prevent the jack from slipping ¢
.&,.
A WARNING
--You or your passengers cou ld be injured
while changing a wheel if you do not fol­
low safety precautions:
- Position the vehicle jack on ly at the
designated lifting points and align the
jack. Otherwise, the vehicle jack could

212 What do I do now?
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 212.
- 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 th e whee l
and the h ub. Remove a ll dirt from these
su rfaces before remo unti ng the wheel.
Notes on wheel change
Pl ease read the informa tion ~ page 192, New
tires and replacing tires and wheels,
if you are
going to use a spare t ire which is different
from the tires on your vehicle.
After you change a tire :
-Check the tire pressure on the spare imme­
diately after mounting .
- Have the wheel bolt tightening torque
che ck e d with a torqu e wrench a s soon as
possible b y your auth orized Audi dealer or
a qualified ser vice station .
- With steel and alloy wheel rims , the wheel
bolts are correctly tightened at a torque of
90 ft lb (1 20 Nm ).
- If y ou notice while changing a tire that the
wheel bolts are co rroded and difficult to
turn , then the y should be repl aced befo re
you check the t ightening torque . -
Repla ce the flat ti re with a new one and
have it installed on your veh icle a s soon as
possible. Remount the wheel cove r.
Until then , dr ive with extra care and at re­
duced speed s.
_& WARNING
-
- If you are going to eq uip your vehicle
wit h tires or rims which differ from those
which were factory installed, then be
sure to read the information
9 page 192,
New tires and replacing tires and
wheels.
- Always store the tools secu rely i n lug­
gage compartment. Othe rwise, in a n ac­
cident or s udden maneuver they cou ld fly
forwa rd, causi ng injury to passengers in
the vehicle.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed the
right direction.
A un idirectional tire can be identified by ar­
rows on the sid ewall ,
which point in the direc­
tion of the rota tion. Yo u m ust follow the
specified direction of rota tion. This is ne ces sa ­
r y in order fo r these tires to develop t heir op ­
timum character istics regard ing grip, road
noise, wear, and hydrop laning.
