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.
-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.
Wheels
-Only use tires that are more
than 6 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.

too high. This heats the tire up
too much. This increases the

-Tires on a vehicle that has
been overloaded can fail sud
denly, including a blowout and
sudden deflation, causing loss

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 241, fig. 195.
Wheels
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 241, fig . 195 .
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
luggage 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 ve
hicle. Consult this manual to
determine how this reduces ..,
