General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tive ly small patch of rubber on each tire that
assures that all -important contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, making
sure that your vehicle and its tires do not have
to carry more weight than they can safe ly han­
d le, avoiding damage from road hazards and
reg ularly inspecting t ires for damage includ­
ing cuts, slashes irregu la r wear and overall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separation and blowouts.
A vo idin g dama ge
I f you have to drive over a curb or similar ob­
stacle, drive very slow ly and as close as possi ­
ble at a right angle to the curb.
A lways keep chem icals including grease, oil,
gasoline and b rake fluid off the tires.
Inspect the tires regularly for damage (cuts,
cracks or bl isters, etc.). Remove any foreign
bod ies embedded in the treads.
St orin g tire s
Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
install them.
When removed, the wheels or tires should be
stored in a cool, dry and preferably dark place .
Store tires in a vertical position if they are not mounted on rims, in a horizontal position if
they are mounted on rims. N
ew tir es
New t ires have to be broken in¢&,. .
The tread depth of new t ires may vary, accord­
ing to the type and make of t ire and the tread
pattern .
Hidden damag e
Damage to tires and r ims is often not readily
vis ible . If you notice unusual vibrat ion or the
vehicle pulls to one s ide, th is may ind icate
that one of the t ires has been damaged . T he
t ir es must be checked immed iate ly by an au­
tho rized Aud i dea le r or q ualified wor kshop.
Unidirecti onal t ires
A un idirectional tire can be identified by ar­
rows on the sidewall, that po int in the direc­
t ion the t ire is designed to rotate. You must
fol low the specified direction of rotation . 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 tires that are old, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in . To reduce the risk of losing
control, a collision and ser ious personal
injuries, drive w ith special ca re for the
fi rst 350 m iles (560 km).
- Driving with worn or damaged tires can lead to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
flation, c rashes and serious personal in­
juries . Have worn or damaged tires re­
p laced immediate ly.
- Tires age even if they are not being used
and can fai l sudden ly, especially at high
speeds. 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.

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 ~page 204.
_& 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 toss of vehicle control. Tires and wheels 259

chains because the vehicle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severe ly dam­
age the wheelhouse and other parts of
the veh icle .
@ Tips
Where snow cha ins are mandatory oncer­
tain roads, this normally also applies to
veh icles with All Wheel Drive.
Wheel bolts
Wheel bolts mu st always be tigh tened to the
correc t torque .
The design of whee l bolts is matched to the
factory in sta lled r ims. If different rims are fit ­
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used . This ensures that wheels are f itted
secure ly and that the brake system f unctions
correctly .
In certain circumstances, you may not use
wheel bolts from a d iffe rent vehicle -even if it
i s the same mode l
¢page 294.
A WARNING
Imprope rly tig hte ned or maintained whee l
bolts can be come loose causin g loss of
contro l, a co llision and serious persona l in­
jury .
- Alw ays keep the w heel bolts and the
th reads in the wheel hubs clea n so the
wheel bolts can turn easily and be prop­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the w heel h ubs. They can
become loose while driving if greased or
o iled, even if tightened to the specif ied
torque.
- Only use wheel bolts that belong to the rim being installed.
- Never use different whee ls bolts on your
vehicle .
- Always maintain the co rrect tightening
torq ue for the wheel bo lts to reduce the
Tire s an d wheel s 265
risk of a wheel loss. If the tighte ning tor­
que of t he wheel bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing . If the tighte ning torque is
too h igh, the wheel bol ts and threads
can be damaged and the whee l can be­
come loose.
(I) Note
The specified torque for the whee l bolts is
90 ft lb ( 120 Nm) with a tole ranc e of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. Afte r cha nging a whee l, the torq ue
must be checked as soon as possible wi th a
torque w rench -prefe rably by an au thor­
i z ed Audi dealer or qualif ied workshop .
Low aspect ratio tires
Your Audi is facto ry-eq uipped with low aspect
ratio tires. These tires have been thoro ughly
tested and been se lected specifically for your
model for their superb performance , road fee l
and handling under a variety of driving cond i­
tions . Ask your authorized Audi dealer for
more details.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's size
designation . The numera l rep resents the ratio
of the t ire's sidewall height in relation to its
t read width ex pressed in perce ntage. Conven ­
tion al tires have a he igh t/w idth ratio of 60 or
more.
The performance of low-aspe ct-ratio tire s is
particularly sensitiv e to improper infla tion
pres sure. It is therefore important that l ow
a spect ratio tires are inflated to the specified
pre ssure and that the inflation pressure is
regularly checked and maintained. Tire pres·
sures should be checked at least once a
month and always before a long trip
