You can also use all season tires instead of
winter t ires . Please note that in some coun­
tries where w inter t ires are required, only
w inter t ires with the
& symbol may be per­
m itted.
Snow chains
Snow chains improve trac tion in the snow.
"' Only install snow chains on the front wheels.
This applies also to ve hicles w ith 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 max imum permitted speed when d riv­
ing with snow chains . Do not ex ceed 30 mp h
(50 km/h).
Snow chains not only imp rove the
driving in win­
ter road cond itions, but also the
braking .
Use of snow chains is only perm itted with certain
r im/t ire combinations due to tec hnical reasons .
Check w ith an authorized Aud i dealer o r autho r­
iz ed A udi Service Fac ility to see if yo u may use
snow cha ins.
Use
fine-mesh snow chains . They must not add
mo re than 0.53 inch (13 .5 mm) in height , includ­
in g the chain lock.
You must remove the chains when driving on roads that are
free of snow. When roads are free
of snow, snow chains can impair handling and
damage the t ires, and t he cha ins w ill quickly be
destroyed.
_& WARNING
Us ing in co rrect snow chains o r inst alling snow
chains incorrectly can result in loss o f vehicle
cont rol, which inc reases t he risk of an acci­
dent.
([) Note
Snow chains can damage the rims/whee l cov­
ers * if the chains come into direct con ta ct
Wh eel s
with them. Remove the whee l covers* fi rst .
Use coated snow chains .

Low aspect ratio tires
Your Audi is factory -equ ipped with low aspect ra­
tio t ires . These tires have been thorough ly tested
and been selected spec ifically for your model for
their superb performance, road fee l and handling
under a var iety of dr iv ing condit ions . Ask your au­
thorized Aud i dea le r fo r more detai ls .
The low aspect rat io of these tires is indica ted by
a numeral of
55 or less in the t ire 's size des igna­
tion . The numeral represents the ratio of the
t ir e's s idewa ll height in relation to its t read width
exp ressed in perce ntage. Conve ntiona l tires have
a height/wid th ra tio of 60 or more.
The performance of low-asp ect-ratio tir es is par­
ticularly sen sitive to improper inflation pres ­
sure. It is therefore important that low aspect ratio tire s are inflated to the specified pressure
and that the inflation pressure i s regularly
checked and maintained. Tire pressures should
be checked at lea st once a month and alway s
before a long trip
¢ page 22 7 .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more easi ­
l y by impact with potho les, curbs, gullies or
ridges on the road, particularly if the tire is un ­
der i nflated.
In order to minimize the occurrence of impact
damag e to the tires of yo ur v ehicle, we recom­
mend that you observe the following preca u­
tions:
- Always maintain recommended inflation pres­
sures . Check yo ur tire pressure every 2,000
m iles (3,000 km) and add air if necessary.
- Dr iv e carefully on roads w ith potholes, deep
gullies or ridges. The impact from dr iving
through or over such obstacles can damage
233

Wheels
you r tires. Impact with a cu rb may also cause
damag e to your tires .
- After any impact, immediately inspect your
tires or have them inspected by the nearest au­
thorized Audi dea ler. Replace a damaged tire as
soon as possib le.
- Inspect yo ur tires every 2,000 miles (3,000 km)
f or damage and wear. Damage is not always
easy to see. Damage can lead to loss of air and
underinflation, which could eventually cause
tire failure . If you believe that a tire may have
been damaged, replace the t ire as soon as pos­
s ible .
- These tires may wear more quickly than others .
- Please a lso remember that, w hile these t ires
deliver responsive handling, they may r ide less
comfortably and make more no ise than other
cho ices .
Reduced perform ance in winter /cold season
conditions
All tires are designed fo r certa in purposes. The
low aspect ratio, ultra hig h pe rformance t ires
or iginally insta lled on you r vehicle a re intended
for max imum dry and we t road performa nce and
handling. They are not s uita ble fo r cold, snowy or
icy weathe r cond itions. If you drive under those
circumstances, you shou ld equip your vehicle
with all-s eason or winter tires, which offer b etter
traction under those condit ions. We suggest you
use the recommended snow or all-season tires
specif ied for your vehicle, or their equivalent .

tion regarding winter tires.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Q ua lity grades c an be found where app licab le on
the tire side wall between tread shoulde r and
maximum section width
¢ page 217, fig . 188.
For example : Tread wea r 200, Trac tion AA , Tem­
pe ra ture
A .
All passenger car tires must conform to Federal
Safety Requi rements in add ition to these grades.
234
Tre ad wear
The tread wear g rade is a compara tive rating
based on the wear rate of the tire when tested
u nder controlled conditions on a specified gov­
e rnment test course .
Fo r example, a tire g raded 150 wou ld wear one
and one half (1 1/2) times as we ll on the govern ­
ment course as a t ire graded 100.
The re lative pe rformance of tires depends upon
the actual cond itions o f the ir use, however, and
may depa rt sign ificantly from the no rm due to
variations in driv ing habits, service practices and
differences in road character istics and climate.
Traction
The traction grades , from highest to lowest, a re
AA, A, B and
C. Those g rades rep resent the tire 's
ability to stop on wet pavement as measured un ­
der controlled conditions on specified govern­
ment test s urfaces 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 t he tire's resistance to the
generat ion 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
of performance on the laboratory test wheel than
the minimum requ ired by law .
A WARNING
-
The t ract ion g rade assigned to this t ire is
based on straight-ahead br aking traction
tes ts, and does not include acceler ation, cor­
nering, hydroplaning or pea k traction charac­
teristics .

..... N
0 ::..:: co ..... ..... & WARNING
The temperature grade for this tire is estab­lished for a tire that is properly inflated and
not overloaded. Excess ive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
& WARNING
-
-
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
U) General notes
App lies to vehicles: with tire pressure mo nitoring system
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
ve hicle manufact urer on the vehicle placa rd o r
tire inflat ion press ure label.
(If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
be l, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been
eq uipped with a tire pressu re monitoring system
(TPMS) that illuminates a low tire pressure te ll­
tale when one or more of your t ires is significant­
ly under- inflated. Accordingly, when the low tire
pressure tellta le illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper press ure. Driving on a s ignifi­
cantly under-inflated tire causes the tire to ove r­
h eat and can lead to t ire failure. Unde r-inflation
a lso reduces fuel e fficiency and tire tread life,
and may a ffec t the vehicle's handling and stop ­
p ing ability .
P lease note that the TPMS is not a substit ute for
p roper tire main tenance, and i t is the drive r's re­
sponsib ility to ma intain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale .
Wh eel s
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not ope rating properly. The TPMS ma l­
funct ion indicator is combined with the low t ire
pressure telltale. When the system detects a
malfunction, the telltale will flash for app roxi­
mately one m inute and t hen rema in continuously
illuminated. This seque nce w ill cont inue upon
s u bsequent vehicle star t-ups as long as the mal­
funct ion exists.
When the malfunction indicator is illum inated,
the system may not be able to detect o r signal
l ow tire p ressure as intended. TPMS malfunct ions
may occur fo r a v arie ty of reaso ns, including the
insta llation of replacement or al ternate tires or
whee ls on the vehicle that p revent the TPMS
from functioning proper ly . Always check the
TPMS ma lfunction te lltale after replacing one or
more tires or wheels on yo ur vehicle to ensure
that the rep lacement or a lternate tires and
wheels allow the TPMS to continue to function prope rly.
' If the Tire Pressure Monitoring System
indicator appears

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction.
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire w ith a t read pattern in­
tended for use in a specif ic direction, please note
the following:
- The direction of rotation is marked by an
arrow
on the side of the tire.
- If the spare tire has to be inst alled in the inco r­
rect direction, use the spare tire on ly tempora ­
r il y since the tire will not be a ble to ac hieve its
optimum performance characterist ics with re­
gard to aquaplan ing, no ise and wear.
- We recommend that you pay part icu lar atten­
tion to th is fact d uring wet weather and that
you adjust your speed to matc h road condi­
tions .
- Rep lace the flat tire w ith a new one and have it
installed o n your veh icle as soon as possib le to
restore the hand ling advan tages of a un id irec­
t ional tire.
Notes on wheel changing

if yo u are going to use a sp are tire
which is d iffe rent from the t ires on your ve hicle.
Af ter yo u cha nge a tire :
-Check the tire pressure on the spare immedi­
ately after installation .
- Have the wheel bolt t ightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or quali­
fied workshop.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of 90
