8,_ 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.
-Only use tires that are more
than six years old when abso­
lutely necessary and drive
carefully when doing so.
Wheels
-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.
Tire wear/damage

Check the tires regularly for wear .
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear .
-Have an authorized Audi dealer

the Infotainment system
¢page 231, ¢page 233 .
.,,.Check the pressure in the emer­
gency tire* /spare tire*. Always maintain the maximum temper­
ature that is specified for the
tire.
A WARNING
Always adapt the tire pressure to your driving style and vehicle load.
-Overloading can lead to loss of vehicle control and increase
the risk of an accident. Read
221

Wheels
and follow the important safe­
ty precautions in
q page 224,
Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­
creases tire wear and has a
negative effect on driving and

Please note the important safe­
ty precautions regarding tire pressure ¢
page 221 and load
limits¢
page 224.
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
224
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

Low aspect ratio tires
Your Aud i is f actory-equipped wi th low aspec t ra­
t io tires. The se tir es h ave bee n thor oughly te sted
and b een se lected s pecific ally fo r yo ur model fo r
their superb perfo rmance , road feel and hand ling
un der a va riety of driving conditions. As k yo ur au ­
thor ized Audi dealer for mo re details .
Th e low aspect ratio of these tires is indi cate d by
a nume ra l of
55 or less in t he tire's size desig na­
tion. The nume ra l r ep resents the rat io of t he
tire's sidewall he ight i n relat ion to its tread wi dth
expressed in pe rcentage. Conventional tires have
a heig ht/w idt h rat io o f 60 o r mo re.
The performance of low-aspect-ratio tires is par­
ticularly sensitive to improper inflation pres­
sure. It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should
be checked at least once a month and always
before a long trip~
page 221.
228
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more eas i­
l y by impact with potho les, curbs, gullies or
r idges on the road, particularly if the tire is un ­
der inflated.
In orde r to mi nimize the occurrence of impact
damage to the tires o f yo ur vehicle, 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 a ir if necessary.
- Dr ive carefully on roa ds w it h potholes, deep
gullies o r ridges. The impact from dr iv ing
throug h or over such obstacles can damage
your t ires. Impac t with a curb may a lso ca use
damage to yo ur tir es.
- After a ny impact, immed iate ly inspect you r
tires or have them inspected by the nearest au ­
t horize d Aud i dealer . Replace a damage d tire as
soo n as poss ible .
- Inspec t your tir es ev ery 2,000 m iles (3,000 km)
for d amage and wear . Damage is no t always
easy to see . Da mage ca n lead to loss o f air and
un derinfla tion, w hich could eve ntually ca use
t ire f ailure. If yo u be lieve th at a tir e m ay h ave
been dam age d, rep la ce the tire as soon as pos ­
sible .
- These tire s may wea r mo re quick ly th an ot hers.
- Ple ase also remember th at , while t hese tires
delive r respo nsive h andli ng, they may rid e less
c omforta bly an d make mo re noise than o ther
choices .

Uniform t ire quality grading
- Tread wear
- T raction AA A B C
- T emperatu re ABC
Quality grades ca n be found where applicable on
the ti re side wall between tread shoulder and
maximum sect ion w idth
¢ page 211, fig. 190.
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 wea r
The
tr ead w ear grade is a comparat ive rating
based on the wear rate of the t ire when tested
under controlled conditions on a specified gov­
ernment test course.
F or examp le, a t ire graded 150 would wear one
and one ha lf
( 1 1/2) times as well on the govern ­
ment course as a tire graded
100 .
The relative perfo rmance of tires depends u po n
the actua l conditions of their use, however, and
may depart significant ly from the norm due to
va riations i n driving habits, service practices and
d ifferences in road characteristics and climate.
Traction
The
traction grades, from highest to lowest, are
AA, A, Band
C. T hose grades represent the tire's
ab ility to stop on wet pavement as measured un­
de r contro lled conditions on specified gove rn­
ment test surfaces of asphalt and concrete . A tire
marked C may have poor traction performance
¢ _& .
Temperatur e
The
temperature grades are A (the highest), B ,
and C, representing the tire's resistanc e to the
generation of heat and its ability to diss ipate
Wh eel s
heat when tested under cont rolled conditions on
a specified indoor laboratory test wheel.
Sustained high temperat ure can cause the mate­
r ia l of the tire to degenerate and reduce t ire life ,
and excessive tempera ture can lead to s udden
tire failure ¢,& .
T he grade
C corresponds to a level of perfo rm­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Sa fety Standa rd
No.
109. Grades Band A represent higher levels
of pe rformance on the laboratory test wheel than
the minim um req uired by law.
A WARNING
-
The tract ion grade assigned to this t ire is
based o n straight -ahead braking traction
tests, and does no t include acceleration, co r­
n ering, hyd roplaning or pea k traction cha rac­
t erist ic s .
A WARNING
The temperature grade fo r this tire is estab­
lished for a tire that is properly infl,;1ted and
not overloaded . Excessive speed, underinfl a­
tion, o r excessive loading, either separately or
i n comb inat ion, can cause heat bu ildup and
possib le tire fai lure .
A WARNING
-
-Temperature grades apply to tires that are
p roperly inf lated and not ove r or under inflat­
ed.
Tire pressure monitoring system
(l) General notes
Each tire, including the spare (if provided),
shou ld be checked monthly when cold and inflat­
ed to the inflat io n pressure recommended by the
vehicle manufacture r on the veh icle placard or
t ir e infla tion p ressure labe l. (If your ve hicle has
t ir es of a diffe re nt si ze t han t he si ze ind icated on
t h e ve hicl e p lacard or tire inflat io n pres sure la­
bel, you sho uld dete rm ine the proper tire in fla-
t ion press ure for those tires) . ..,.

Wheels
As an added safety feature, your vehicle has been
equipped with a tire pressure mon itor 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 ti re 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
malfunction, the telltale will flash for approxi ­
mately one m inute and then remain cont inuously
illuminated . This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists .
When the malfunct ion indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS 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.

Tire pressure monitoring system
Applies to: vehicles with Tire Pressure Monitoring System in­
dicator
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 194 Instrumen t cl uster : indicator l ig ht with me ssage
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumfer­
ence and vibration characteristics of the individu­
al tires. If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
Rt] and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle
¢ page 231. The tire pressure mon i­
toring system only monitors the tire pressure you have stored . Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢page 221, fig. 193.
Tire tread circumference and vibrat ion character­
istics can change and cause a tire pressure warn­
ing if :
- the tire pressure in one or more tires is too low.
- the tire has structural damage.
- the tire was replaced or the tire pressure was
changed and it was not stored¢
