Tires
General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle.
Tires may be the least ap preciated and most
a bused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehi cle, particularly considering the compara-
tively small patch of rubber on eac h tire that
assures that a ll-important contact between
you, you r vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safe ly han-
d le, avoiding damage from road ha za rds and
reg ularly inspec ti ng t ires for damage includ-
ing cuts, slashes irreg ula r wear and ove rall
condition are the most important things that
you can do to he lp avoid s udden tire failure in-
cluding tread separat ion and blowouts.
Avoiding damage
If you have to d rive ove r a curb or similar ob-
stacle, drive very slow ly and as close as possi -
ble at a right angle to the curb.
Always keep chemicals incl ud ing grease, oil,
gasoline and brake fluid off t he t ires .
Inspect the t ires regularly for damage (cuts,
cracks or blisters, et c.). Remove any fo reign
bod ies embedde d in the t reads.
Storing tires
Mark t ires when you remove them to indicate
the direction of rotation . This ensures you to
be ab le to mount them correctly when you re-
install them .
When removed, the whee ls or t ires should be
sto red in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims .

New tires
New tir es have t o be broken in ¢ & .
The tread depth of new t ires may vary, accord-
ing to the type a nd make of t ire and the tread
pa tte rn.
Hidden damage
Damage to tires and rims is ofte n not readily
visible . If you notice unusual vibrat ion or the
vehicle pulls to one side, th is may ind icate
that one of the t ires has been damaged . The
tir es must be che cked immed iate ly by an au-
t horized Audi dea ler or q ua lified wor kshop .
Unidirectional tires
A un idirec t ional tire can be identified by ar-
rows on the sidewa ll, that po int in the direc-
tion the t ire is desig ned to rotate. You mus t
follow the specified d irection of rot ation . This
is necessary so that these tires can develop
their optimum characteristics regarding grip,
road noise, wear and hydrop laning resistance.

A WARNING
New tires or t ires that are o ld, worn or
damaged can not provide maximum con-
trol and braking ability .
-
- New tires tend to be slippery and must
be broken in. To reduce the risk of losing
contro l, a collision and ser ious personal
inj uries, d rive with special ca re fo r the
first 350 m iles (5 60 km).
- Driving with worn or damaged tires can
lead to loss of control, sudde n t ire fail -
ure, including a blowout and sud den de-
fla tion, cras hes a nd se riou s personal in-
juries . Have wo rn or damaged t ires re-
placed immediate ly.
- Tires age even if they a re not being used
an d can fai l sudden ly, especially at hig h
spee d s. Tires that are more than 6 years
old can only be used in an emergency
