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 poss ible on all four
wheels .
290
.,.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 ¢&, .
The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
so only use the spare tire* tempo
rarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
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 .,.

0 a, .... N ,.... N .... g :r ..
use a spare tire* that is 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 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
and sudden deflation that can
cause the vehicle to crash.

-Tires on a vehicle that has
been overloaded can fail sud
denly, including a blowout and

-Always make sure that the to tal load being transported -
including the weight of a trail

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 make 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 placard
(tire inflation pressure label)
c::> page 293, fig. 267 .
Wheels
2. Determine the combined
weight of the driver and pas sengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver and passengers
from "XXX" kilograms or "XXX"
pounds shown on the sticker
c::> page 293, fig . 267 .
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex
ample, if the "XXX " amount
equals
1400 lbs. and there will
be five
150 lbs . passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 X 150) = 650
lbs .)
5. Determine 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 capacity calculat
ed in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer
will be transferred to your ve
hicle. Consult this manual to
determine how this reduces .,..

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra-
o tio tires. These t ires have been thorough ly tested co
~ and been selected specifically for your model for ,.....
~ their supe rb performance, road feel and handli ng 0 0 :c '
under a var iety o f dr iv ing condit ions . Ask your au
thorized Audi dea le r for more detai ls.
T he low aspect rat io of t hese tires is indicated by
a nu meral o f
55 or less in the tire's si ze des igna
tion . The n umera l represents the ratio of the
tire's sidewa ll height in relation to its tread width
expressed in percentage . Conve ntiona l tires have
a height/width ratio of 60 or more .
The performance of low-aspect- ratio tires is par
ti cula rly sen siti ve to imprope r inflation p res
sure. It is the refore important that low aspect
rat io tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained . Tire pressures should
be checked at lea st once a month and always
before a long trip
¢ page 293 .
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged more eas i
ly by impact w ith potho les, curbs, gullies or
ridges on the road, particularly if the tire is un
der inflated .
In order to m in imize the occurrence of impact
damage to t he tires of yo ur vehicle , we recom
me nd tha t you observe the following preca u
tio ns:
- Always maintain recommended inflat ion pres
sures. Check you r ti re pressu re every 2,000
m iles (3,000 km) a nd add air if necessary.
- Dr ive carefully on roads w it h potholes, deep
gullies o r ridges. The impact from dr iving
t hrough or over such obst acles can damage
your tires. Impac t with a cur b may also ca use
damage to your tires.
- After a ny impac t, im med iate ly inspect yo ur
t ires or have them inspe cted by the neares t au
t horized A udi dealer. Replace a damaged tire as
soon as possible.
- I nspect 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 air and
underinflation, wh ich could event ually cause
tire fa ilure . If you believe that a tire may have
been damaged, replace the tire as soon as pos
sible .
- These tires may wear more quickly than others . .,.
299

Wheels
- Please a lso remember that, wh ile these tires
deliver responsive handling, they may ride less
comfortably and ma ke more noise than other
cho ices.
Reduc ed performance in winter /cold s eason
condit ions
All tires are designed for certain purposes. The
low aspect ratio, ultra high performance t ires
or iginally i nstalled on your vehicle are intended
for maximum dry and wet road performance and
handling . They are not s uitable for cold, snowy or
icy weathe r cond itions.
If you drive under those
circumstances, you s hou ld equ ip your ve hicle
with a ll-season or win ter tires, wh ic h offe r bette r

Tire Pressure Monitoring
System (AS, S8)
(D General notes
A ppl ies to: AS, 58
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat
ed to the inflation pressure recommended by the
veh icle manufact urer 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
be l, you should determine the proper tire infla
tion pressure for those tires).
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure te ll
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
p roper tire maintenance, and it is the driver's re
sponsib ility to ma intain correc t tire p ressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres
sure telltale.
Your veh icle has also bee n eq uipp ed w ith a TPM S
mal function indicator to indicate when the sys
tem is not operat ing 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 mi nute and then remain cont inuously
illuminated . This sequence will continue upon
Wheels
subsequent vehicle start-ups as long as the mal
function exists .
When the malfunction indicator is illuminated ,
the sys tem may not be able to detect or signal
low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, including the
i nsta llation of replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replac ing one or
more tires or wheels on your vehicle to ensure
that the replacement or a lternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears
