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 separat ion 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 r ims, 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 s ide, 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 s id 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 o ld, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
also be broken-in. To reduce t he risk of
losing control, a collision and se rious
pe rsonal injuries, drive w it h specia l care
for the first 350 miles (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 .

Glossary of tire and loading terminology
Accessory weight
means the comb ined weight (in excess of
those standard items which may be replaced)
of automatic tra nsmission, power steering,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory-installed equip­
ment (whether installed or not) .
Aspect ratio
means the ratio of the height to the width of
the tire in percent . Numbers of 55 or lower in­
d icate a low sidewall for improved steering re­
sponse and better overall handling on dry
pavement .
Bead
means the pa rt of the ti re that is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead s eparation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire.

ter months . Low temperatu res signifi­
cantly decrease the elastic ity of summer
t ires, which affects traction and braking
ability. If summer tires are used in very
co ld temperatures, cracks can form on
the tread bars, res ulting in permanent
ti re damage that can cause loud drivi ng
noise and unbalanced tires. Aud i is not
responsib le for this type of damage.
- Burn ished, polished or chromed rims
must not be used in winter weather. Th e
surfa ce of the rims does not have suffi­
c ien t cor rosion pro te cti on for this and
c o ul d be pe rmanen tly damaged by road
salt or similar substances. This damage
is not covered by warranty.
Cold tir e inflation pressure
me ans the t ire press ure re commended by the
vehicle manufacturer fo r a tire o f a des igna ted
size that has not bee n driven for more than a
couple of miles (k ilomete rs) at low speeds in
the three hour pe riod before the tire press ure
is measured or adjusted.
Curb weight
means the weight o f a motor vehicle with
standard equipment including the maximum
capacity of fuel, o il, and coolant, air cond i­
tion ing and additional weight of optiona l
equipment.
E xtra load tire
means a tire design to operate at higher loads
and at higher inflation pressures than the cor­
responding standard tire. Extra load tires may
be identified as "XL", "xl", "EXTRA LOAD", or
"RF" on the sidewall.
Gross Axle Weight Rating ("GAWR")
means the load-carrying capacity of a single
axle system, measured at the tire-ground in-

by Audi are specially matched to the charac­
ter istics of the vehicle and can make a major contribution to good road holding and safe
handling when in good condition and properly
inflated
¢
&..
We recommend that all work on tires and
whee ls be performed by an authorized Audi
dealer. They are familiar with recommended
procedures and have the necessary special
tools and spare parts as well as the proper fa­
cilities for disposing of the old tires.
Authorized Audi dea lers have the necessary
information about technical requirements for
installing or changing tires and rims .
Replacing tires and wheels
Tires should be replaced at least in pairs and
not individually (for example both front tires
or both rear tires together).
Be sure to read and heed the information to
the tire pressure mon itor ing system *
co page 249 .
Always buy replacement radia l tires that have
the same spec ifications as the tires approved
for your vehicle by Audi. Replacement tires
must a lways have the same load rating speci­
fication as the origina l equipment or approved
optiona l tires listed in the table¢
page 234 .
Audi-approved specification tires are specia lly
matched to your vehicle and its load limits,
and can contribute to the important roadhold­
ing, driving characteristics, and safety of the
vehicle. The table
(c;, page 234) lists specifica­
tions of the tires approved for the Audi mod­ els covered by your Owner's Literature .

general, the greater the number of p lies, the
more weight a tire can support . Tire manufac­
turers also must indicate the materials in the
tire, wh ic h include steel, nylon, polyester, and
others.

A WARNING
-Us ing incorrect or unmatched tires and/
or wheels or improper tire and wheel
combinations can lead to loss of contro l,
co llision and serious persona l injury .
- Always use tires, rims and wheel bo lts
that meet the specifications of orig inal
factory-installed t ires or other combina­
t ions that have been spec ifically ap­
proved by the vehicle manufacturer.
- 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
o ld can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used ti res on yo ur vehicle if
yo u are not su re 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.
- All four wheels must be fitted with radia l
t ires of the same type, size (roll ing c ir- cumference) and the same tread pattern
.
Driving with different tires reduces vehi­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires - only use
the spare t ire fo r a short pe riod of time
and d rive with extra care . Refit the nor­
mal road wheel as soon as safely poss i­
b le.
- Never d rive faster than the max imum
speed for which the tires on you r vehicle
are rated because tires that are dr iven
faster than their rated speed can fai l
suddenly .
- Overloading tires cause heat build-up,
sudden tire fa ilure, including a blowout
and sudden deflation and loss of cont ro l.
- Temperature grades apply to tires that are properly inflated and not over or un­
de rinf lated .
- For technica l reasons it is not always
possible to use whee ls from other
veh icles -in some cases not even wheels
from the same veh icle model.
- If you install wheel trim discs on the ve­
hicle wheels, make sure that the a ir flow
to the brakes is not blocked. Reduced air­
f low to the brakes can them to overheat,
increas ing stopp ing distances and caus­
ing a co llision.
- Run flat tires may only be used on veh icles that were equipped with them
at the factory. The veh icle must have a
chassis designed for run flat tires and a
f a ctory -inst alled tire pressure monitor­
ing sys tem * that indicates a loss of tire
pressu re . I ncorrect use of run flat tires
can lead to vehicle damage or accidents.
Check with an authorized Audi dealer or
tire specialist to see if your vehicle can be
equ ipped w ith run flat t ires. If run flat
tires are used, they must be installed on
all fo ur wheels . Mix ing tire types is not
pe rm itted.

(D Note
-For technica l reasons, it is not genera lly
possib le to use the whee l rims from oth­
er vehicles. This can hold true for wheels
of the same vehicle type.
- If the spare ti re is different from the tires that you have mounted on your ve­hicle (for example w inter t ires or wide
profile t ires), then use the spare t ire for a
short period of time only and drive with
extra ca re. Replace the flat tire with the
tire match ing the others on you r vehicle
as soon as possible.
- Never dr ive without the valve stem cap.
The valves could ge t damaged.
@) For the sake of the environment
Dispose of old t ires in accordance with the
local requ irements.
Uniform tire quality grading
- T read wear
- T raction AA A BC
- T emperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum sect ion w idth
¢ page 242,
fig . 193.
For e xample: Tread wear 200 , Tract ion AA ,
Temperature A.
All passenger car tires must confo rm to Feder­
a l Safety Requirements in addition to these
grades.
Tr ead wea r
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course.
F or examp le, a tire graded 150 wou ld wear
one and one half (1 1/2) times as well on the
government course as a tire graded 100 .
The rela tive performance of t ires depends

ever, and may depa rt s ignificantly from the
norm due to variations in driving habits , serv­
ice practices and differences in road character­
istics and cl imate.
Traction
T he traction grades, from highest to lowest,
are AA, A, Band
C. Those g rades represent the
ti re's ability to stop on wet pavement as
measured under contro lled conditions on
specified government test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance
¢ A .
Temper ature
The temperature grades are A (the highest),
B, and C, representing the tire's resistance to
the generation of heat and its ability to dissi­ pate heat when tested under controlled condi­
tions on a specif ied indoor laboratory test
whee l.
Sustained h igh temperature can cause the
mater ial of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failure
¢ A .
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet
under the Federal Motor Vehicle Safety Stand ­
ard No . 109 . Grades Band A represent higher
levels of perfo rmance on the labo rato ry test
whee l than the minim um requ ired by law.

Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
The snow chains must have low-profile links
and must not be thicker than 0.53 inch
(13.5 mm), including the lock .
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
~ 0. For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
~ WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different sizes. Always make sure to follow the in­
structions provided by the snow chain
manufacturer .
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
(D Note
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it . Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
(j) Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
vehicles with all wheel drive.

Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bolts is ma tched to the
factory inst alled rims. 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 fitted
securely and that the brake system functions
correctly.
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model~
page 2 77.
&_ WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control , a collision and serious personal in­
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can become loose while driving if greased or
oiled, even if tightened to the specified
torque .
- Only use wheel bolts that belong to the
rim being installed .
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tightening torque for the wheel bolts to reduce the risk of a wheel loss. If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be­
come loose.
(I} Note
The specified torque for the wheel bolts is
90 ft lbs . (120 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque wheel bolts .,..
