2020 AUDI R8 COUPE wheel bolts

Wheels

replaced 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.

Z\ 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.
—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



252

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.

Determining correct load
limit
Use the example below to calcu-
late the total weight of the pas-
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be overload-
ed.
Steps for Determining Correct
Load Limit
1. Locate the statement “THE
COMBINED WEIGHT OF OCCU-
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS” on your vehicle’s placard
(tire inflation pressure label)
=> page 254, fig. 193.
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
=> page 254, fig. 193.
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
258
be five 150 lbs passengers in
your vehicle, the amount of
available cargo and luggage
oad 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
uggage load capacity calculat-
ed in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your vehi-
cle. Consult this manual to de-
termine how this reduces the
available cargo and luggage
load capacity of your vehicle.
> Check the tire sidewall
(= page 245, fig. 191) to deter-
mine the designated load rating
for a specific tire.
Wheel bolts and rims
Wheel bolts

Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo-
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them > A\.

Wheels


ZA\ WARNING
Wheel bolts that are tightened or repaired in-
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi-
cation, see > page 276, Finishing.
— Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
— Only use wheel bolts that fit the rim.
— Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident.

Winter tires significantly improve the vehicle's
handling when driving in winter conditions. Be-
cause of their construction (width, compound,
tread pattern), summer tires provide less traction
on ice and snow.
> Use winter tires on all four wheels.
> Only use winter tires that are approved for your
vehicle.
> Please note that the maximum permitted
speed may be lower with winter tires > A\ in
General information on page 244. An author-
ized Audi dealer or authorized Audi Service Fa-
cility can inform you about the maximum per-
mitted speed for your tires.
> Check the tire pressure after installing wheels
=> page 254.
The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0.157 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re-
gardless of the remaining tread.
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear, and fuel
consumption.
@) Tips
You can also use all season tires instead of
winter tires. Please note that in some coun-
tries where winter tires are required, only win-
ter tires with the 4 symbol may be permit-
ted.
Snow chains improve both driving and braking in
winter road conditions.
> Only install snow chains on the rear wheels.
> Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol-
low the instructions from the manufacturer.
> Note the maximum speed of 30 mph
(50 km/h). Observe the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author-
ized Audi Service Facility to see if you may use
snow chains.
You must remove the snow chains on roads with-
out snow. Otherwise, you could impair driving
ability and damage the tires.

ZA\ WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci-
dent.
CG) Note
— Snow chains can damage the rims and
wheel covers* if the chains come into direct
contact with them. Remove the wheel cov-
ers* first. Use coated snow chains.

— Using snow chains that add more than 0.53
in (13,5 mm) of height can severely damage
the wheel housings and other vehicle com-
ponents.
@) Tips
When using snow chains, it may be advisable
to limit the ESC > page 87.

Emergency assistance

> Inflate the tire to between 29 psi (200 kPA)
and 36 psi (250 kPA) and read the pressure on
the gauge.
> If this tire pressure is not reached, remove the
filler hose. Drive slowly approximately 33 feet
(10 m) forward or in reverse so that the sealant
can be distributed in the tire. Inflate the tire
again > A\.
ZA\ WARNING
— Read and follow the manufacturer's safety
precautions on the compressor and in the in-
structions on the bottle of sealant.
— Ifa tire pressure of 29 psi (200 kPA) cannot
reached after inflating for 6 minutes, then
the tire is too severely damaged. Do not con-
tinue driving.
— If the tire cannot be repaired with the tire
sealant, see an authorized Audi dealer or au-
thorized Audi Service Facility for assistance.
@) Tips
Do not operate the compressor for more than
six minutes continuously, or it can overheat.
Once the compressor has cooled, you can con-
tinue to use it.

Applies to: vehicles with tire mobility kit



> Affix the sticker that says "max. 50 mph (max.
80 km/h)" that is provided with the tire mobili-
ty kit within the driver's field of vision.
> Stop the vehicle after driving for about 10 mi-
nutes and check the tire pressure.
> If the tire pressure is lower than 19 psi (130
kPA), then the tire is too severely damaged. Do
not continue driving.

Z\ WARNING
Pay attention to the following after repairing
the tire:
— Do not drive faster than 50 mph (80 km/h).
— Avoid hard acceleration or braking and driv-
ing fast around curves.
— The vehicle may become more difficult to
control.


— If the tire is too severely damaged, see an
authorized Audi dealer or authorized Audi
Service Facility for assistance.


(@) For the sake of the environment
You can give the used tire sealant bottle to an
authorized Audi dealer or authorized Audi
Service Facility for disposal.
G) Tips
Remember to obtain a new bottle of sealant
from an authorized Audi dealer or authorized
Audi Service Facility after repairing a tire.

>©.
> Install the wheel bolts and tighten them gently
using the hex socket.
> Remove the alignment pins and also tighten
the remaining wheel bolts.
> Carefully lower the vehicle using the vehicle
jack*.
276
> Tighten the wheel bolts in a diagonal pattern
using the wheel wrench.
The wheel bolts must be clean and loosen and
tighten easily. Check the contact surfaces for the
wheel and hub. Contaminants on these surfaces
must be removed before installing the wheel.

ZA WARNING
— Read and follow the important information
and notes under > page 251.
— Never use the hex socket in the screwdriver
handle to tighten the wheel bolts. Using the
hex socket will not achieve the required
tightening torque, which increases the risk
of an accident.
(!) 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.
Unidirectional tires
A unidirectional tire profile is identified by arrows
on the tire sidewall that point in the running di-
rection. You must always maintain the specified
running direction. This is necessary to ensure the
tire's optimal performance in regard to adhesion,
running noise, and friction, and to reduce the risk
of
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.
> Reinstall the caps on the wheel bolts if necessa-
ry.
> Store the vehicle tool kit in its designated
place.
> Make sure that the wheel that was removed,
the vehicle tool kit, and the vehicle jack* are se-
curely stored in the luggage compartment
=> page 54.
