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 a ll-impo rtant contact between
you, your 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 hazards and
reg ularly inspecting t ires for damage includ
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in
cluding tread separation and blowouts.
Avoiding damage I f you have to drive over a curb or similar ob
stacle, drive very s low ly and as close as possi
b le at a right angle to the curb.
A lways keep chem ica ls includ ing gre ase, o il,
gasoline and b rake fluid off the ti res .
Inspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
Storing tires 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 t hem.
When removed, the whee ls or t ires should be
stored 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 tire
s
New t ires have to be broken in¢&,. .
T he 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 r ims is ofte n not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle p ulls to one side, th is may ind icate
t h at one of the t ires has been damaged . Th e
t ir es m ust be checked immed iate ly by an au
tho rized Aud i dea le r or q uali fied wor ks hop.
Unidirectional t ires
A un idirectional tire can be identified by ar
rows on the sid ewa ll, that po int in the direc
t ion the t ire is desig ned to rotate. You mus t
f ol low the specified d irection of rotation . This
is necessary so that these tires can develop
their optimum characterist ics regarding grip,
road no ise, wear and hyd rop 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 co llision and ser ious personal
in jur ies, d rive w ith 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, sudden tire fail
ure, including a blowou t and sudden de
fl ation, c rashes and seriou s personal in
juries . Have wo rn or damaged t ires re
p laced immediate ly .
- T ires age even if they are not being used
an d 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 specia l care and at low
speed.

-Never mount used tires on yo ur vehicle if
yo u 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.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al
ways stop as soon as it is safe to do so
and check the wheels and tires for dam
age .

A 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 t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es 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.

Driving with different tires reduces vehi
cle handling and can lead to a loss of
co ntrol.
- If the spare tire is not the same as the
t ires that are mounted on the veh icle -
for example with winter tires - on ly use
the spare tire for a short period of time
and dr ive with extra ca re. Refit the nor
ma l road whee l as soon as safely possi
ble.
- Never drive faste r than the maximum
speed for which the tires o n your veh icle
are ra ted because ti res th at are driven
faster than their rated speed can fail
sudden ly .
- Over loading t ires c ause heat b uild- up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- T emperature grades app ly to tires t hat
are properly inflated and not over o r un
derinflated.
- F or technical reasons it is not a lways
possible to use wheels from other
vehicles -in some cases not even w heels
from the same vehicle model.
- If you insta ll wheel trim discs on t he ve
hicle whee ls, make sure that the air f low
to the brakes is not blocked. Reduced air
flow to the brakes can them to overheat, increasing stopping distances and caus
ing a collision.
- Run flat t ires may on ly be used on
vehicles that were equ ipped w it h them
at the facto ry. The vehicle must have a
chassis des igned for run f lat t ires and a
fac to ry-installed t ire p ress ure moni to r
ing system that ind ic a tes a loss of tire
pressure. Incorrect use of run flat tires
can lead to vehicle damage or accidents .
Check with an a uth orized Audi dea ler or
t i re spec ialist to see i f your vehicle can be
equipped with run flat tires. If r un flat
t ires a re used, they must be installed on
all four wheels . M ixing tire types is not
permitted . (D Note
-For technical reasons, it is not generally
poss ible to use the w heel rims from oth
er ve hicles. T his can hold tr ue for wheels
of the same vehicle type.
- If the spare tire is diffe rent from the
tires that you have mounted on your ve
hicle (for example winter tires or wide
profi le tires), then use the spare tire for a
short period of time only and drive w ith
extra care. Replace the flat tire w it h the

All passenger car ti res must conform to Feder
al Safety Req uirements in add ition to these
grades .
Tread wear
The tread wear g rade is a comparative rating
based on the wear rate of the tire when tested
u nder contro lled conditions o n a specified
government test course.
F o r example, a tire gra ded 150 wo uld wear

snow c hains are suitably cove red . Check
the position of the snow chains after
driving a few yards and correct if neces
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
Where snow cha ins are mandatory oncer
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory insta lled r ims . If different rims are fit
ted, the correct wheel bo lts with the right
length and correctly shaped bolt heads must
be used. This ensures t hat wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
i s the same model
¢ page 227.
A WARNING
Imprope rly tig htened or maintained wh eel
bolts can become loose ca using loss of
con trol, a collision and serious person al in
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be p rop
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose w hile driving if greased or
o iled, even if tig htened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tig htening
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 197
que of t he whee l bolts is too low, they
can loosen and come out when the vehi
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago
nally. After changing a whee l, the tor que
must be checked as soon as possible with a
torq ue w rench -prefe rably by an au thor
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng under a var iety of driving condi
tions . Ask your authorized Audi dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in pe rce ntage. Conven
t iona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
particularly sensitive to impr oper inflation
pre ssure .
It is therefore important that low
a spect ratio tire s are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s
sures should be checked at least once a month and always befo re a long trip
¢ page 186, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.

Run-flat ti res
Introduction
Applies to vehicles: with Run -f lat tires
Run-flat tires help keep you moving if a tire
goes flat.
Re inforced sidewalls give the tires run-flat ca
pability if tire pressure is lost .
We recommend that r un-flat tires on ly be
m ounted on vehicles that were orig inally
equipped with these special tires at t he facto
ry and have a Tire Pressure Moni toring Sys
tem .
Run-flat tires can be identified by the letters
"RSC" on the tire sidewall.
If you do change the tires on your veh icle from
norma l to run- flat tires, you must b uy the
special rims required for run-flat tires, and the
T ire Pressure Monitor ing System must be re
programmed by an authorized Aud i dealer o r
other qualified worksho p .
What do run-fl at tires do?
These special tires have r un-flat capabilities
that help keep you moving if a t ire loses pres
sure and goes flat . Under favorable conditions
ti res can be dr iven
at least 30 miles (50 km) ,
but you mus t not dr ive faster than 50 mph Ill-
Page 204 of 244
202 Tires and wheels
(80 km/h)
¢ page 202, Driving with run -flat
tires .
When it is not possible to continue
driving, even with run-flat tires?
- If the E lectronic Stabilization Control (ESC)
is not working or keeps coming on.
- If the Tire Pressure Monitoring System does
not work .
-If the tire has been severely damaged, in a
crash, for example. The tread can separate
from a damaged tire as the whee l turns , and
hit parts of the vehicle , such as the fuel tank
filler neck, fuel lines or brake lines.
- Do not continue driving if severe vibration
occurs or if the tire starts to smoke because
the tire is running hot.
- Do not continue driving if damage to the
tire, such as cracks in the sidewall, appears.
A WARNING
Improper use of run-flat t ires can cause
veh icle damage that can lead to loss of ve
hicle control, a crash and serious pe rsonal
injury.
- Run-flat tires can only be used with spe cial rims.
- Run-flat tires must always be mon itored
with a properly programmed Tire
P re
ssure Mon itor ing System.
- Always inspect a tire that has lost air to
make sure it is safe to drive with the tir e
in the run-flat mode.
- Never drive with run-flat tires that have
