Tires and wheels
different tire speeds. For this rea­
son, in case of emergency, 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.
-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 6 years old when abso-
222
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.
Tire wear/damage

Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.

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
(c> page 214, fig. 168) 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* consis t of mul tiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
disassemble them
Q ,& .
Tires and wheels
A 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, refer to~
page 242, A~er changing a
wheel.
- 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
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
Q _& . An
authorized Audi dealer or authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires.
.. Check the tire pressure after installing wheels
Qpage 224.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.157 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
A WARNING
-Never drive faster than the maximum per­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
the risk of an accident because it can cause
the tire to burst.

Emergency assistance
-When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way¢
page 245 .
-The wheel bolts shou ld be clean and easy to
t ur n. 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.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction .
U sing a spare tire with a tread pattern
intended for use in a specific direction
When using a spare t ire with a tread pattern in­
tended for use in a specific direction, please note
the following:
- The direct ion of rotation is marked by an arrow
on the side of the tire.
- If the spare tire has to be insta lled in the incor­
rect direction, use the spare tire only tempora­
r ily since the tire w ill not be able to achieve its
optimum performance characteristics with re­
gard to aquaplaning, noise and wear .
- We recommend that you pay part icular atten­
tion to th is fact during wet weather and that
you adjust your speed to match road condi­
tions.
- Replace the flat tire with a new one and have it
installed on your veh icle as soon as possible to
restore the handling advantages of a unidirec­
tional tire.
Notes on wheel changing
Please read the information ¢ page 221 if you
are going to use a spare tire which is different
from the tires on your vehicle.
After yo u change a tire:
-Check the tire pressure on the spare immedi-
ately after installation.
