Wheels and Tires
General information
~check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
~ If driving over curbs or similar
obstacles, drive slowly and ap ­
proach the curb at an angle.
~ Have faulty tires or rims re­
placed immediately.
~ Protect your tires from oil,
grease and fuel.
~ Mark tires before removing
them so that the same running direction can be maintained if
they are reinstalled .
~ Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as possible.
(i}) Note
-Please note that summer and
winter tires are designed for
the conditions that are typical i n those seasons. Audi recom­
mends using winter tires dur­
i ng the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
236
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
tions. The surface of the r ims
does not have sufficient corro­
sion protection for th is and
could be permanently dam­
aged by road salt or similar
substances.

Wheel s
® Mud and snow capability
"M/5" or "M+S" indicates the tire
has characteristics that make it
suitab le for driving on mud and
snow. ~ indicates a winter tire.
@ Composition of the tire cord
and materials
The number of plies indicates the
number of rubberized fabric lay­
ers in the tire . In general : the
more layers, the more weight a
tire can carry. Tire manufacturers
must also specify the materials
used in the tire. These include
steel, nylon, polyester and other materials.
@ Ma ximum permitted load
This number indicates the maxi­
mum load in kilograms and
pounds that the tire can carry.
@ Uniform tire quality grade
standards for treadwear,
traction and temperature resistance
T readwear, traction and tempera­
ture ranges ~
page 253.
@ Running direction
The arrows indicate the running
direction of unidirectional t ires.
You must always follow the speci-
238
fied running direction
~ page 264 .
(8) Maximum permitted
inflation pressure
This number indicates the maxi­
mum pressure to which a tire can
be inflated under normal operat­
ing condit ions.
Glossary of tire and loading
terminology
Accessory we ight
means the combined weight (in
excess of those standard items
which may be replaced) of auto­ matic transmission, power steer­
ing, power brakes, power win­
dows, power seats, radio, and
heater, to the extent that these
items are available as factory -in ­
stalled equipment (whether in­
stalled or not).
Aspect rat io
means the rat io of the height to
the width of the tire in percent.
Numbers of 55 or lower indicate a
low sidewall for improved steer­
ing response and better overa ll
handling on dry pavement.

Wheels
use a spare tire* that is the same
circumference as the regular
tires .
A 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-
244
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
Fig. 206 Tire profile: treadwear indica­
tor
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.
-Have an authorized Audi dealer or authorized repair facility

Emerg ency s it u ation s
_& WARNING
If you do not screw the towing loop complete­
ly, it could come out of the threaded hole
wh ile the vehicle is be ing towed causing dam­
age to the vehicle and poss ible serious per­
sonal injury.

kit.
" Press inward strongly on the upper right side of
