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.
.,.M ark 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.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom
mends using winter tires dur
ing the winter months. Low
temperatures significantly de crease the elasticity of summ
er tires, which affects traction
Wheels
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 rims
does not have sufficient corro
sion protection for this and
could be permanently dam aged by road salt or similar
substances.

"M/5" or "M+S" indicates the tire
is suitable 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 ti re . These inc lude
stee l, nylon, polyester and other
materials.

This number indicates the maxi
mum load in kilograms and
pounds that the tire can carry.

Glossary of tire and loading
terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto matic t ransmission, power steer
ing, power brakes, power win
dows , powe r seats, radio, and
heater, to the extent tha t these
items are avai lab le as factory- in
stalled equipment (whether in
s t alled or not).
Aspect ratio
means the ratio of the height to
the w idth of the tire in percent.
Numbers of 55 or lower indicate a
low sidewall for improved steer
ing response and better overall
handling on dry pavement .
Bead
means the part of the tire that is
made of steel wires, wrapped or
reinfo rced by ply cords and that is

A WARNING
- If the ti re pressu re indicator appears in the
display, reduce your speed immediate ly and
avoid any hard steering or braking maneu
vers. Stop as soon as possib le and check the
t ires and t heir pressure.
- The driver is responsib le for maintaining the
correct tire pressure. You must check the
t ire pressure regu larly .
- Under certain conditions (such as a sporty
dr iv ing style, winter cond itions or unpaved
roads), the tire pressure mo nitoring system
indicator may be delayed.
- Do not use run-flat tires on your vehicle. Us
ing them when not permitted ca n lead to
vehicle damage or accidents.
(D Tips
- The t ire pressure monitoring system can al
so stop work ing when there is an ESC mal
funct io n.
- Using snow chains may result in a system
malfunction.
- The t ires with the identification "AO" or
"RO" ¢
