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 .
.,. Only use tires with the same de
sign, size (rolling circumference)
and as close to the same tread pattern as poss ible on all four
wheels .
178
.,.Do not replace tires individually .
At least replace both tires on the
same axle at the same time.
.,. Audi recommends that you use
Audi Original Tires. If you would
like to use different tires, please
note that the tires may perform
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 t ire 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.
Applies to: vehicles with all wheel
drive: 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 dam aged by different wheel speeds . .,.

For this reason, in case of emer
gency, only 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.
-Only use tires that are more
than six years old when abso-
Wheels
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

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.,.
183

Wheels
passengers that the vehicle is in
tended to carry ("seating capaci
ty") with an assumed weight of 1 SO lbs. (68 kg) for each passen
ger at a designated seating posi
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer hitch and the tongue weight of
the loaded trailer must be includ
ed as part of the vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas
sengers in the vehicle or passen
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli
ance sticker label located on the
184
driver's side B-pillar ¢ page 181,
fig. 149.
~ WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and
increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has been overloaded can fail sud
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to tal load being transported -including the weight of a trail
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.

Determining correct load
limit
Use the example below to calcu
late the total weight of the pas
sengers and luggage or other
things that you plan to transport
so that you can ma ke sure that
your vehicle will not be overload ed .
Steps for Determining Correct
Load Limit
1 . Locate the statement "THE
COMBINED WEIGHT OF OCCU PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle 's pla card
(tire inflation pre ssure l abel)
¢ page 181, fig. 149.
2 . Determine the combined
weight of the drive r and pas
s engers that will be riding in
your vehicle.
3 . Subtra ct the combined weight
of the driver and passengers
from
" XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 181 , fig. 149 .
4. The re sulting figure equals the
available amount of cargo and
luggage load capacity. For ex
ample, if the
" XXX" amount
equals 1400 lbs. and there will
Wheels
be five 1 SO lbs. pa ssengers in
your vehicle, the amount of available cargo and luggage load capacity i s 650 lb s.
(1400-750 (5 X 150) = 650
lbs.)
5. Determin e the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex
ceed the available cargo and luggage load capa city cal culat
ed in Step 4 .
6. If your vehi cle will be towing a
trailer, load from your trailer
will be transferred to your ve
hicle. Con sult thi s manual to
determine how this reduces
the available cargo and lug gage load capacity of your vehi
cle.
..,.Check the tire sidewall
(¢page 171 , fig. 147) to deter
mine the designated load rating
for a specific tire.

& WARNING
Using incorrect snow chains or insta lling snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acc i

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra
tio tires . These t ires have been thoroughly tested
and been se lected specifica lly for you r model for
the ir supe rb performance, road feel and handling
u nder a va riety of d riving conditions. As k yo ur au
thor ized Audi dealer for mo re de tails.
The low aspect ratio of these t ires is indicated by
a numera l of
55 or l ess in the tire's size desig na
tion . The numera l rep resents t he rat io of the
tire's sidewall he ight in rela tion t o its tread w idth
expressed in percen tage. Conventional t ires have
a height/w idth ratio of 60 or more .
The performan ce of low -aspect-r atio tire s is par
ticularly sen sitiv e to impr oper infla tion pre s
s ure . It is therefore important that low a spect
ratio tires are infl ated to the specified pressure
and that the inflation pre ssure is regularl y
checked and ma inta ined . Tire pre ssure s should
be checked at least once a month and alwa ys
before a long trip
c> page 181.
What you can do to avoid tire and rim damage
Low aspect rat io tires can be damaged more easi
ly by impact with potholes, curbs, gul lies or
ridges on the road, pa rticularly if the tire is un
de rinflated .
In order to minimize the occurrence of impact
damage to the t ires of your ve hicle, we recom
mend that you observe the follow ing precau
tions:
Wh eel s
-Always maintain recommended inflat ion pres
sures . Check your tire pressure every 2,000
m iles (3,000 km) and add air if necessary .
- Drive carefully on roads wit h potholes, deep
gu llies or ridges . T he impact 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, 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 a lways
easy to see . Damage can lead to loss of a ir and
unde rinflat ion, wh ic h could eventually cause
t ire fa ilu re . If yo u be lieve th at a t ire may have
been damaged, repla ce the tire as soon as pos
sible.
- These tires may we ar 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 winter/cold season
conditions
All t ires are des igned for certai n pu rposes. The
l ow aspect ratio, ultra h igh 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
t ract ion under those conditions . We suggest you
u se the recommended s now or a ll-season tires
spe cified for your veh icle, o r the ir equiva lent.
Refer to

t ion regard ing winter tires.
Uniform tire quality grad ing
- Tread wear
- Traction AA ABC
- Temperature ABC
187

Wheels
Quality grades can be found where applicable on
the tire side wall between tread shoulder and maximum section width
¢ page 171, fig. 147.
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
188
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 e fficiency and tire tread life,
and may affect the vehicle's handling and stop p ing ability .
Pl ease no te that the TPMS is not a substi tute for
p roper tire maintenance, and it is the drive r's re
sponsib ility to maintain cor rect tire pressure,
even if under-inflation has not reached the leve l
to tr igger illum inat ion of the TPMS low tire pres
sure telltale.
Your vehicle has also been eq uipped with a TPMS
mal funct ion indicator to indicate when the sys
tem is not operating properly. The TPMS mal
function indicator is combined w ith the low tire
pressure tellta le. Whe n the system detects a
malfunct ion, the telltale will flash for approx i
mately one min ute and then remai n cont inuo usly
i llum inated. This sequence will continue upon
s ubseq uen t ve hicl e start- ups as long as the m al
f u nction ex ists.
When the malfunct io n in dicator is ill uminated,
the system may not be ab le to detect or signa l
l ow tire press ure as intended . TPM S malfu nctions
may oc cur for a var iety of reasons, incl uding the
installation of replacement or alternate ti res o r
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after rep lacing one or
more t ires or whee ls on your ve hicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to cont inue to funct ion
p roperly.
