Tires
General notes
Tires may be the least appreciated and most
abus ed parts of a motor vehicle .
Tires may be the least ap preciated and most
a b used parts of a motor vehicle . T ires 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.
Ma intaining 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
r eg ularly inspec ting t ires for damage i nclud
ing cuts, slashes irreg ular wear and ove ra ll
condition are the most important things that
you can do to he lp avoid s udden tire failure in
cluding tread separat ion and b lowouts.
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
b le at a right angle to the curb.
A lways keep chemicals incl ud ing grease, o il ,
gasoline and brake fluid off the t ires .
I nspect the t ires regularly for damage (cuts,
cracks or b listers, e tc.). 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 . T his ensures you to
be ab le to mount them correctly when you re
in stall 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 r ims, in a horizontal pos it ion if
they are mounted on rims .

Hidden damage
Damage to tires and r ims is ofte n not readily
visible . If you notice unusual v ib rat io n or the
vehicle p ulls to one s ide, th is may ind icate
that one of the t ires has been damaged . T he
tir es m ust be che cked immed iate ly by an au
t horized Audi dea le r or q ua lified wor kshop .
Unidirectional tires
A un idirec tional tire can be identified by ar
rows on the s idewa ll, that po int in the direc
tion the t ire is desig ned to rotate. You mus t
f ol low the specified d irection o f rotation . T his
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 r isk of losing
contro l, a co llision and ser ious personal
in ju ries, d rive with special ca re fo r the
fi rst 350 m iles ( 560 km).
- Driving with worn or damaged tires can
le ad to loss of control, sudde n tire fail
ure, including a blowout and sud den de
fla tion, c ras hes and se riou s personal in
juries . Have wo rn or d amaged t ires re
placed immediate ly.
- Ti res age even if they are no t being used
an d can fai l sudden ly, especially at hig h
spee ds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith special care and at low
speed.

256 Tires and wheels
Incorrect wheel alignment
Incorrect wheel alignment can cause exces
sive tire wear, impairing the safety of the vehi
cle. If tires show excessive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.
All Wheel Drive
Vehicles with quattro must always have tires
of the same size, construction and tread type.
For details see Qpage 202 .
.&_ WARNING
Sudden tire failure can lead to loss of con
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of"hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower speeds.
- Never mount used tires on your vehicle if
you are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
