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

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
Page 210 of 252

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.
