Tyre service life
Correct inflation pressures and sensible driving habits
will increase the service life of your tyres.– Check the tyre pressures at least once a month.
– The tyre pressures should only be checked when the
tyres are cold. The slightly raised pressures of warm tyres
must not be reduced.
– The pressures must be altered to suit major changes in
the load being carried.
– Avoid fast cornering and hard acceleration.
– Inspect the tyres for irregular wear from time to time.The service life of your tyres depends on the following factors:
Tyre pressure
Under-inflation or over-inflation will reduce the life of the tyres
considerably and also impair the car's handling. The inflation pres-
sures are listed on a sticker on the driver's door pillar.
Correct inflation pressures are very important, especially at high
speeds. The pressures should therefore be checked at least once a
month and before starting a journey.
Driving habits
Fast cornering, heavy acceleration and hard braking (squealing
tyres) all increase tyre wear.
Wheel balancing
The wheels on new vehicles are balanced. However, various factors
encountered in normal driving can cause them to become unbal-
anced, which results in steering vibration.Unbalanced wheels should be rebalanced, as they otherwise cause
excessive wear on steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted or if a tyre is repaired.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the
safety of the vehicle. If you notice excessive tyre wear, contact your
Audi R8 dealer.
WARNING
•
Always adapt the tyre pressure accordingly when the vehicle
load changes.
•
Under-inflated tyres flex more and can overheat at continuous
high speeds. This can cause tread separation and tyre blow-out,
which could result in an accident. Always observe the recom-
mended tyre pressures.For the sake of the environment
Under-inflated tyres will increase the fuel consumption.

Wheels and tyres 172Remove wheel covers (if fitted) and trim rings before attaching
snow chains. For safety reasons cover caps must then be fitted over
the wheel bolts. These are available from Audi R8 dealers.
Remove the chains when roads are free of snow. Otherwise they will
impair handling, damage the tyres and wear out very quickly.
Four-wheel drive: Where snow chains are compulsory on certain
roads, this normally also applies to cars with four-wheel drive. Snow
chains may only be fitted to the rear wheels (also on vehicles with
four-wheel drive).Tyre pressure monitoring systemApplies to vehicles: with tyre pressure monitoring systemIntroduction
The tyre pressure monitoring system keeps a check on the
inflation pressures of the four road wheels while you are
driving.The system warns the driver in the event of a loss of pressure by
means of symbols and messages in the instrument cluster display.
The system employs sensors on the wheels. The radio signals from
these sensors are transmitted to the tyre pressure monitoring
system.
Please bear in mind that the tyre inflation pressure is also influ-
enced by the temperature of the tyre. For every 10°C increase in the
tyre temperature the pressure will normally increase by about
0.1 bar. The tyre heats up while the vehicle is being driven and the
tyre pressure will rise accordingly. For this reason, you should only
adjust the tyre pressures when they are cold (i.e. approximately at
ambient temperature).
To ensure that the tyre pressure monitoring system works reliably,
you should check and, if necessary, adjust the tyre pressures at
regular intervals.The tyre pressures recommended for your vehicle are given on the
sticker attached to the driver's door pillar.
Initialising the tyre pressure monitoring system
The inflation pressures for two sets of wheels (e.g. with winter and
summer tyres) are stored on your vehicle. You can change between
these two sets of wheels any number of times without re-initialising
the system.
The tyre pressure monitoring system must be re-initialised by your
Audi R8 dealer if a new set of wheels is used or the electronic
sensors are renewed.
Warning lamp
 lit
If the tyre pressure is more than 0.5 bar below the reference value,
the display will show the tyre symbol
 with a corresponding
message, such as Tyre pressures too low ⇒.
WARNING
•
If the warning lamp
 lights up you must slow down immedi-
ately and avoid any severe braking or steering manoeuvres. As
soon as you can do so safely, stop and check the tyres and the tyre
pressures.
•
Never re-adjust the tyre inflation pressure when the tyre is hot.
This can cause serious damage to the tyre or even a blow-out,
which could result in an accident.
•
Under-inflated tyres flex more and can overheat at continuous
high speeds. This can cause tread separation and tyre blow-out,
which could result in an accident.For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre
wear.

Note
•
Responsibility for ensuring that the tyres are correctly inflated
remains with the driver; the system can only provide assistance.
•
Only adjust the inflation pressure of the tyres when they are at
approximately ambient temperature.
•
The sensors and valves do not have to be detached or changed
round when fitting new tyres. Only the valve core needs to be
replaced, and if necessary the valve and the electronic components
in the wheel.
•
After using the Tyre Mobility System* the tyre pressure moni-
toring system may malfunction. The sensor for the tyre pressure
monitoring system must therefore be renewed by a qualified
workshop.
Applies to vehicles: with tyre pressure monitoring systemMalfunctionsIf the tyre pressure monitoring system is inoperative, the tyre
symbol or “TPMS” will appear on the display. This can have various
causes:•
One of the wheel sensors or other related components may not
be working.
•
Snow chains can interfere with the signals emitted by the
sensors so that the system cannot function properly.
•
The tyre pressure monitoring system may be inoperative due to
radio interference.
•
Radio systems operating on the same frequency, such as radio
headphones or two-way radios inside the vehicle, produce strong
electromagnetic fields which can cause temporary interference.
•
If the fault persists, take the vehicle to a qualified workshop.

Tightening wheel bolts– Fit the box spanner as far as it will go over the wheel
bolt
5).
– Grip the box spanner as close to the end as possible and
tighten the bolt firmly by turning clockwise.
Have the tightening torque of the wheel bolts checked as soon as
possible with a torque wrench. The correct tightening torque is
120 Nm.
The inflation pressure must be checked as soon as possible.
Put the tools and jack back in the luggage compartment.
WARNING
The wheel bolts must not be loosened – this would cause a safety
risk.
Note
•
Do not use the hexagonal socket in the screwdriver handle to
loosen or tighten the wheel bolts.
•
If you notice that the wheel bolts are corroded and difficult to
turn, they must be replaced before having the tightening torque
checked.
•
In the interest of safety, drive at moderate speeds until the tight-
ening torque of the wheel bolts has been checked.
Jump-startingBefore starting the engine
If necessary, the engine can be started by connecting it to
the battery of another vehicle.If the engine should ever fail to start because of a discharged
battery, the battery can be connected to the battery of another
vehicle to start the engine. Suitable jump leads are required.
Both batteries must be rated at 12 Volts. The capacity (Ah) of the
booster battery should not be significantly lower than that of the
discharged battery.
Jump leads
The jump leads must be heavy enough to carry the starter current.
Refer to the details given by the manufacturer.
Only use jump leads with insulated battery clamps.
Positive cable – usually red
Negative cable – usually black
WARNING
•
When it is discharged the battery can freeze at temperatures
around 0°C. A frozen battery must first be thawed out before
connecting the jump leads, as it could otherwise explode.
•
Please note the safety warnings referring to working in the
engine compartment ⇒page 155.Note
•
There must be no contact between the two vehicles as otherwise
current could flow as soon as the positive terminals are connected.
•
The discharged battery must be properly connected to the
vehicle's electrical system.
5)An adapter is required to tighten the anti-theft wheel bolts ⇒page 182.
