2015 AUDI RS5 CABRIOLET tire pressure

224 Tires and wheels
are located on a sticker on
the driver's side B-pillar.
-Only when all tires on the vehicle are filled to the cor­rect pressure, the tire pres­
sure monitoring system*
can work correctly.
-The use of incorrect tire pressure values can lead to
accidents or other damage.
Therefore it is essential that
the driver observe the speci­
fied tire pressure values for
the tires and the correct pressures for the function of
the tire pressure monitoring
system*.
-Always inflate tires to the
recommended and correct
tire pressure before driving
off.
-Driving with underinflated
tires bend more, letting
them get too hot resulting
in tread separation, sudden
tire failure and loss of con­
trol.
-Excessive speed and/over­ loading can cause heat
build-up, sudden tire failure
and loss of control.
-If the tire pressure is too
low or too high, the tires will wear prematurely and
the vehicle will not handle
well.
-If the tire is not flat and you
do not have to change a
wheel immediately, drive at
reduced speed to the near­
est service station to check
the tire pressure and add air
as required.
(D Note
Driving without valve stem
caps can cause damage to
the tire valves. To prevent
this, always make sure that
factory installed valve stem
caps on all wheels are secure­ ly mounted on the valve.
@ For the sake of the environment
Underinflated tires will also
increase the fuel consump­
tion.
Tires and vehicle load limits
There are limits to the amount
of load or weight that any vehi­
cle and any tire can carry. Ave­
hicle that is overloaded will not
handle well and is more diffi­
cult to stop. Overloading can not only lead to loss of vehicle
control, but can also damage .,.

226 Tires and wheels
The tire pressure label on your
Audi also lists the maximum
combined weight of all of the
occupants and luggage or other
cargo that the vehicle can carry. For the location of the label
¢page 217, fig. 182.
A WARNING
-
Overloading a vehicle can
cause loss of vehicle control,
a crash or other accident, se­
rious personal injury, and
even death.
-Carrying more weight than your vehicle was designed to carry will prevent the ve­
hicle from handling properly
and increase the risk of the
loss of vehicle control.
-The brakes on a vehicle that has been overloaded may
not be able to stop the vehi­
cle within a safe distance.
-Tires on a vehicle that has
been overloaded can fail
suddenly, including a blow­
out and sudden deflation,
causing loss of control and a
crash .
-Always make sure that the
total load being transported
- including the weight of a trailer hitch and the tongue
weight of a loaded trailer­ does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rat­
ing.
Determining correct load
limit
Use the example below to cal­
culate the total weight of the
passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be
overloaded.
Steps for Determining
Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehi­
cle's placard (tire inflation
pressure label)
¢page 217,
fig. 182.
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" kilo­
grams or
"XXX" pounds
shown on the sticker
.:::> page 217, fig. 182.
4. The resulting figure equals
the available amount of car­ go and luggage load capaci ­
ty . For example, if the
"XXX"
amount equals 1400 lbs.
and there will be five 150
lbs . passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­
pacity 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
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing
a trailer, load from your trail­
er will be transferred to your
vehicle. Consult this manual
to determine how this re­
duces the available cargo
and luggage load capacity of
your vehicle .

rating for a specific tire.
Tire service life
The service life of tires depends
on a lot of different things in­
cluding proper installation and
balancing, correct tire pressure
and driving style.

We recommend that all work
on tires and wheels be per­
formed by an authorized Audi
dealer. They are familiar with recommended procedures and
have the necessary special tools
and spare parts as well as the
proper facilities for disposing of
the old tires.

about technical requirements

Replacing tires and wheels
Tires should be replaced at least in pairs and not individu ­
ally (for example both front
tires or both rear tires togeth­ er) .
Be sure to read and heed the in­
formation to the tire pressure monitoring system*
¢page 239.
Always buy replacement radial
tires that have the same specifi­
cations as the tires approved
for your vehicle by Audi. Re­
placement tires must always
have the same load rating spec­
ification as the original equip ­
ment or approved optional tires
listed in the table

The tire pressure label located on driver's side B-pillar
(r=>page 217, fig. 183) lists the
specifications of the original
equipment tires installed on
your vehicle at the time it was
manufactured.
Federal law requires tire manu­
facturers to place standardized information on the sidewall of
all tires¢
fig. 186. This infor­
mation identifies and describes
the fundamental characteris­
tics, the quality grade of the
tire and also provides a tire identification number for safety
standard certification and in
case of a recall.
Tire specifications
Knowledge of tire specifications
makes it easier to choose the
correct tires. Radial tires have

This number is the greatest
amount of air pressure that
should ever be put in the tire
under normal driving condi­
tions.
.&_ WARNING
-Using incorrect or unmatch­ ed tires and/ or wheels or improper tire and wheel
combinations can lead to loss of control, collision and
serious personal injury.
-Always use tires, rims and wheel bolts that meet the
specifications of original
factory-installed tires or
other combinations that have been specifically ap­
proved by the vehicle manu­
facturer.
-Tires age even if they are
not being used and can fail
suddenly, especially at high
speeds. Tires that are more
than 6 years old can only be used in an emergency and
then with special care and
at lower speeds.
-Never mount used tires on your vehicle if you are not sure of their "previous
histo­
ry." Old used tires may have
been damaged even though
the damage cannot be seen
that can lead to sudden tire
failure and loss of vehicle
control.
-All four wheels must be fit­ ted with radial tires of the
same type, size (rolling cir­
cumference) and the same
tread pattern. Driving with different tires reduces vehi­
cle handling and can lead to
a loss of control.
-If the replacement tire is
not the same as the tires
that are mounted on the ve­
hicle -for example with win­
ter tires - only use the re­
placement tire for a short
period of time and drive
with extra care. Refit the normal road wheel as soon
as safely possible.
-Never drive faster than the maximum speed for which
the tires on your vehicle are
rated because tires that are
driven faster than their rat-
ed speed can fail suddenly. ...
