2018 AUDI TT ROADSTER wheel bolts

Wheels
Because the spare tire* is differ­
ent from the regular tires instal­ led on the vehicle (such as winter
tires or wide tires), only use the
spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re­ placed with a regular tire as soon
as possible.
Applies to: vehicles with all wheel
drive: all four wheels must be
equipped with tires that are the
same brand and have the same
construction and tread pattern so
that the drive system is not dam­
aged by different wheel speeds.
For this reason, in case of emer­
gency, only use a spare tire* that
is the same circumference as the
regular tires.
& WARNING ~ -
-Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
252
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more
than six years old when abso­
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when not permitted can lead to ve­
hicle damage or accidents.
- If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.

Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OCCU­PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS" on your vehicle's placard
(tire inflation pressure label)
c:> page 254 , fig. 189 .
2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3 . Subtract the combined weight
of the driver and passengers
from
"XXX " kilograms or "XXX"
pounds shown on the sticker
c:> page 254 , fig. 189 .
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex­
ample, if the
" XXX" amount
equals 1400 lbs and there will be five 150 lbs passengers in
your vehicle, the amount of available cargo and luggage load capacity is 650 lbs
(1400-750 (5
X 150) = 650 lbs)
5 . Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex­
ceed the available cargo and
258
luggage load capa city cal culat­
ed in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer
will be tran sferred to your ve­
hicle. Con sult thi s manual to
determine how this reduces
the available cargo and lug­
gage load capacity of your vehi ­
c le .
~check the tire sidewall
(c:> page 245 , fig. 187) to deter­
mine the designated load rating
for a spe cifi c tire.

Emergency assistance
{QJ Note
When removing or installing the wheel, the
rim could hit the brake rotor and damage the
rotor. Work carefully and have a second per­
son help you.
(D Tips
- When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way
¢ page 278.
-The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Unidirectional tires
A unidirectional tire profile is identified by arrows
that point in the running direction on the tire
sidewall. You must always adhere to the speci­
fied running direction. This is necessary ensure
the tire 's optimum performance in regard to ad­
hesion, running noise, friction and hydroplaning .
To benefit fully from the advantages of the uni­
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
running direction on all of the tires.
Finishing
.,. Reinstall the caps on the wheel bolts if neces­
sary .
.,. Store the vehicle tool kit in its designated
place .
.,. If the removed wheel does not fit in the spare
wheel well, store it securely in the luggage
compartment
¢ page 183.
.,. Check the tire pressure on the installed wheel
as soon as possible.
.,. Check the tire pressure and store it in the Info­
tainment system.
.,. The wheel bol t tightening specification must be
90 ft lbs (120 Nm) . Check it as soon as possible
with a torque wrench. Drive carefully until then.
.,. Have the faulty wheel replaced as quickly as
possible.
278
(D Tips
- 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 tightening torque.
- Drive at reduced speed until you have the
tightening torques checked.
Notes on wheel changing
Please read the information ¢ page 251 if you
are going to use a spare tire which is different
from the tires on your vehicle .
After you change a tire:
- Check the tire pressure on the spare immedi­
ately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible 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 lbs (120 Nm).
- If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire,
they should be replaced before you check the
tightening torque.
- Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble. Remount the wheel cover .
Until then, drive with extra care and at reduced
speeds.
A WARNING
- If you are going to equip your vehicle with
tires or rims which differ from those which
were factory installed, then be sure to read
the information
¢page 251.
-Always make sure the damaged wheel or
even a flat tire and the jack and tool kit are
properly secured in the luggage compart­
ment and are not loose in the passenger
compartment.
- In an accident or sudden maneuver they
could fly forward, injuring anyone in the ve­
hicle.
