use a spare tire that has the same
circumference as the regular
tires.
&_ WARNING -
-Only use tire/rim combina­ tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle . Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident.
Wheels
-Only use tires that are more
than 6 years old when abso­ lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when
not permitted can lead to ve­
hicle damage or accidents.
- If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.

Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
150 lbs. (68 kg) for each passen-
ger at a designated seating

and a special procedure. You must not repair or
disassemble them¢&. .
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct t ightening specifi ­
cation, refer to ¢
page 214, After changing a
wheel .
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of grease.
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Aud i
Service Facility . Never repair or disassemble
rims yourself, because this inc reases the risk
of an accident.
Winter tires
Winter tires s ignificantly improve the vehicle's
handling when driving in winter conditions . Be­
cause of their construction (width, compound,
tread pattern), summer tires provide l ess trac­
tion on ice and snow.
.,. Use winter tires on all four wheels.
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lower with winter tires
q .&,. . An
authori zed Audi dealer or authori zed Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after install ing wheels
q page 201.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .157 inch (4 mm). The character istics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
A WARNING
- Never drive faster than the maximum per­
mitted speed for your tires. This cou ld cause
the tires to heat up too much. This increases
206
-
the risk of an accident because it can cause
the tire to burst.
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires w ith the ~ symbol may be per­
mitted.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive* .
.,. Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol­
low the instructions from the manufacturer.
.,. Note the maximum permitted speed when dr iv­
ing with snow chains. Do not exceed 30 mph (SO km/h).
Snow cha ins not only improve the
driving in win­
ter road conditions, but also the
braking .
Use of snow chains is only permitted with certain
rim/tire combinat ions due to technical reasons .
Check with an author ized Audi dealer or author­
ized Audi Service Facility to see if you may use
snow chains.
The snow chains must have
low-profile links and
must not be thicker than 0.53 inch (13.5 mm),
including the lock.
You must remove the chains when driving on
roads that are
free of snow . When roads are free ..,.

of snow, snow chain s can imp air handling and
damage the t ires, and t he chains will quickly be
destroyed.
A WARNING
Using incorrect snow chains or installing snow
chains incorrect ly can result in loss of vehicle
co ntrol, which increases the risk of an acc i­
dent .
Snow chains can damage the r ims/wheel cov­
ers* if the chains come into d irect contact
w ith them. Remove the wheel covers* first.
Use coated snow chains .
Low aspect ratio tires
Your Audi is facto ry-equipped with low aspect ra­
tio ti res. These t ires have been tho rough ly tested
and been se lected specifically for yo ur model fo r
thei r superb per formance, road feel and handling
under a variety of driving conditions. Ask your au­
thorized Audi dealer for more details .
The low aspect ratio of these t ires is indica ted by
a numera l of
55 or les s in the tire's size designa ­
tion. The numeral represents the ratio of the
tire's sidewall height i n relation to its tread width
expressed in percentage. Conventional tires have
a height/w idth ratio of 60 or more.
Th e performance of low-aspect- ratio tire s is par­
ticularly sensit ive to improper inflation pre s·
sure . It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pre ssure is regul arly
ch ecked and ma intained . Tire pre ssure s should
be checked at least once a month and a lways
before a long tr ip
c> page 201.
What you can do to avoid tire and rim
damage
L ow aspect rat io tires can be damaged more easi­
ly by impact wi th pot holes, c urbs, gull ies or
r idges on the ro ad, p articul arly if the tire is un­
de rinflated.
I n o rder to minimize the occurrence of impact
damage to the t ires of your ve hicl e, we recom-
Wh eel s
mend that you observe the following preca u­
tions:
- Always ma in tain recommended inflat io n pres­
sures. Check yo ur tire pressure every 2,0 00
m iles (3,000 km) and add air if necessary .
- Dr ive c arefully on roads w it h potholes, deep
gullies or ridges . The impac t from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immediate ly inspect your
tires or have them inspected by the nearest au ­
thorized Audi dealer. Replace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not always
easy to see . Damage can lead to loss of air and
underinflation, wh ich could even tually cause
tire fa ilure. If yo u believe that a tire may have
been damaged, replace the tire as soon as pos­
sib le.
- These tires may wear more quickly tha n others .
- Please also remember that, while these tires
delive r responsive ha nd ling, they may ride less
comfortably a nd make mo re noise than other
choi ces.
Reduced performance in winter /cold se ason
conditions
All t ires are des igned for certai n purposes. The
low aspect ratio, ultra high performance tires
o rigi na lly installed on your veh icle are intended
f or maximum dry and wet road performance and
handling . They are not suitable for co ld, snowy or
icy weather conditions . If you drive under those
c ircumstances, you should equip yo ur vehicle
with all-season or winter tires, which offer better
tract ion under those conditions. We suggest you
u se the recommended snow or all-season tires
spec ified for your veh icle, or their equiva lent .

Uniform tire quality grading
- Tread wear
- Traction AA ABC
- Temperature ABC
207

Wheels
Quality grades can be found where applicable on
the tire side wall between tread shoulder and maximum section width
¢ page 191, fig. 156.
For example: Tread wear 200, Traction AA, Tem­
perature
A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov­
ernment test course.
For example, a tire graded 150 would wear one
and one half (1 1/2) times as well on the govern­
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and may depart significantly from the norm due to
variations in driving habits, service practices and differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, Band
C. Those grades represent the tire 's
ability to stop on wet pavement as measured un­
der controlled conditions on specified govern­ ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
¢&_ .
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­ rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure ¢&. .
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard
No. 109 . Grades Band A represent higher levels
208
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING -
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­ nering, hydroplaning or peak traction charac­
teristics .
A WARNING
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
(l) General notes
Appl ies to vehicles: with tire pressure mon itoring system
-
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitor ing system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant-
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure . Under-inflation ..,.

also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunct ion, the telltale will flash for approxi­
mately one minute and then remain continuous ly
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illuminated,
the system may not be ab le to detect or signal
low tire pressure as intended . TPM S malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
