New tires or wheels
Audi recommends having all work on tires or wheels performed by
an authorized Audi dealer or au
thorized Audi Service Facility.
These facilities have the proper
knowledge and are equipped with
the required tools and replace ment parts.
.. New tires do not yet have the
optimum gripping properties.
Drive carefully and at moderate
speeds for the first 350 miles
(500 km) with new tires.
.. use tires of the same construc
tion, size (rolling circumference)
and as close to the same tread pattern as possible on all four
wheels.
11>D0 not replace tires individually.
At least replace both tires on the
same axle at the same time.
11>Audi recommends that you use
Audi Original Tires. If you would like to use different tires, please
note that the tires may perform
324
differently even if they are the
same size ¢
&.-
.,. If you would like to equip your
vehicle with a tire/rim combina
tion that is different from what
was installed at the factory, con
sult with an authorized Audi
dealer or authorized Audi Service Facility before making a pur
chase¢ &,.
If the spare tire is different from
the regular tires installed on the
vehicle - for example, if winter
tires or wide tires are installed -
then only use the spare tire tem porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible .
On
all wheel drive vehicles , all
four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds . For this rea
son, in case of emergency, only
use a spare tire that has the same
circumference as the regular
tires . ""

Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread
pattern, which are bars that are 1/16 in (1.6 mm) high and are
spaced evenly around the tire per pendicular to the running direc
tion
c::> fig. 254 . The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread
wear indicators.
The tires have reached the mini
mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones
c::> A .
Tire rotation
Rotating the tires regularly is rec
ommended to ensure the tires
wear evenly. To rotate the tries,
install the tires from the rear axle
on the front axle and vice versa.
This will allow the tires to have
approximately the same length of
service life.
For unidirectional tires, make
sure the tires are installed accord
ing to the running direction indi-

Hidden damage
Damage to tires and rims can of
ten occur in locations that are
hidden. Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage .
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out
side, drive slowly and carefully to
the nearest authorized Audi deal
er or authorized Audi Service Fa
cility to have the vehicle inspect
ed.
A WARNING
Tread that has worn too low or different tread depths on the
tires can reduce driving safety.
This can especially have a nega
tive effect on handling, on the risk aquaplaning when driving
through water, when driving
through curves and when brak ing, which increases the risk of
an accident.

Low aspect ratio tires
Your Aud i 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 for
their 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 in r elation to its tread width
expressed in percentage. Conventional tires have
a height/w idth rat io of 60 or more.
The performan ce of low-aspect- ratio tire s is par
ticularl y sensiti ve to improper inf lat ion pres
sure . It is therefore impo rtant that low aspect
ratio tir e s are infl ated to the specified pressu re
and tha t the inflation pr essure is regularly
checked and maint ained . Tire pre ssure s should
be check ed at lea st once a month and alwa ys
b efore a long trip<=:>
page 32 7.
What you can do to a void tire and rim
damage
L ow aspect rat io tires can be damaged more easi
l y by impact with potho les, cu rbs, gull ies or
r idges on the road, pa rtic ularly if the tire is un
derinflated.
Wh eel s
In order to min imize the occurrence o f impact
damage to the tires of your vehicle, we recom
mend that you observe the following precau
t ions:
- Always maintain recommended inflation pres
sures . Check your tire pressure every 2,000
m iles (3,000 km) and add air if necessary .
- Drive carefully on roads with potholes, deep
gu llies or ridges . The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immed iate 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 a ir and
underinflation, wh ich could eventually cause
tire fa ilu re . If yo u bel ieve that a tire may have
been damaged, replace the tire as soon as pos
sible.
= These tires may wear mo re quickly tha n others.
- Please also remember that , while these tires
de live r responsive ha nd ling, they may ride less
comfort ably and make more noise t han other
choices .
Reduced performance in w inter /cold season
conditions
All tires are des igned for certai n pu rposes. The
low aspect ratio, ultra high performance tires
origina lly installed on your vehicle are intended
for 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 your vehicle
with all -season or winter tires, which offer better
tract ion under those conditions . We suggest you
use the recommended s now or a ll-season tires
spe cified for your vehicle, o r their equiva lent.

t ion regard ing winter tires.
Uniform tire quality grad ing
- Tread wear
333
Page 336 of 386

Wheels
-Traction AA A BC
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and maximum section width
~ page 317, fig. 253.
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 failur e~ ,& .
The grade C corresponds to a level of perform
ance which all passenger car tires must meet un-
334
der the Federal Motor Vehicle Safety Standa rd
No. 109. Grades Band A represent higher levels
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 indicator
(l) General notes
-
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 veh icle 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 monitoring 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
