We recommend that all work
on tires and wheels be per­
formed by an authorized Audi
dealer. They are familiar with recommended procedures and
have the necessary special tools
and spare parts as well as the
proper facilities for disposing of

This number is the greatest
amount of air pressure that
should ever be put in the tire

tions.
.&_ WARNING
-Using incorrect or unmatch­ ed tires and/ or wheels or improper tire and wheel
combinations can lead to loss of control, collision and
serious personal injury.
-Always use tires, rims and wheel bolts that meet the
specifications of original
factory-installed tires or
other combinations that have been specifically ap­
proved by the vehicle manu­
facturer.
-Tires age even if they are
not being used and can fail
suddenly, especially at high
speeds. Tires that are more
than 6 years old can only be used in an emergency and
then with special care and
at lower speeds.
-Never mount used tires on your vehicle if you are not sure of their "previous
histo­
ry." Old used tires may have
been damaged even though
the damage cannot be seen
that can lead to sudden tire
failure and loss of vehicle
control.
-All four wheels must be fit­ ted with radial tires of the
same type, size (rolling cir­
cumference) and the same
tread pattern. Driving with different tires reduces vehi­
cle handling and can lead to
a loss of control.
-If the spare tire is not the
same as the tires that are
mounted on the vehicle -for
example with winter tires -
only use the spare tire for a
short period of time and
drive with extra care. Refit
the normal road wheel as soon as safely possible.
-Never drive faster than the maximum speed for which
the tires on your vehicle are
rated because tires that are
driven faster than their rat­
ed speed can fail suddenly.
-Overloading tires cause heat build-up, sudden tire fail ­
ure, including a blowout
..

and sudden deflation and loss of control.
-Temperature grades apply to tires that are properly in­
flated and not over or un ­
derinflated.
-For technical reasons it is not always possible to use
wheels from other vehicles_ 1n some cases not even
wheels from the same vehi­
cle model.
-If you install wheel trim discs on the vehicle wheels
I
make sure that the air flow
to the brakes is not blocked.
Reduced airflow to the
brakes can them to over­
heat, increasing stopping
distances and causing a col­ lision.
-Run flat tires may only be used on vehicles that were
equipped with them at the
factory. The vehicle must have a chassis designed for
run flat tires and a factory­
installed tire pressure moni­
toring system* that indi­ cates a loss of tire pressure.
Incorrect use of run flat
tires can lead to vehicle damage or accidents. Check
Tires and wheels 253
with an authorized Audi dealer or tire specialist to
see if your vehicle can be
equipped with run flat tires.
If run flat tires are used
I
they must be installed on all
four wheels. Mixing tire types is not permitted.
(D Note
-For technical reasons, it is not generally possible to
use the wheel rims from
other vehicles. This can hold
true for wheels of the same
vehicle type.
-If the spare tire is different from the tires that you have mounted on your vehicle
(for example winter tires or
wide profile tires), then use
the spare tire for a short pe­ riod of time only and drive
with extra care. Replace the
flat tire with the tire match­ ing the others on your vehi­
cle as soon as possible.
-Never drive without the valve stem cap. The valves could get damaged.

Your vehicle is equipped with all whee l drive,
this will improve traction during winter driv­ ing, even with the standard tires. However, we
strongly recommend that you a lways equ ip a ll
four wheels on your veh icle w ith correctly fit­
ted wi nte r tires or all -season tires, when w in ­
ter road conditions are expected. This also im­
p roves the vehicle 's braking performance and
reduces stopping distances.
Summer tires provide less grip on ice and
snow .
W inter tire s (snow t ires) must always be fitted
on all four wheels.
Ask your authorized Audi dea ler o r qualified
workshop for permitted
w inter t ire sizes. Use
only radia l winter tires .
Winte r ti res lose thei r effectiveness when the
tread is worn down to a depth of
0 .15 7 inch
(4 mm) .
On ly drive with winter tires under winter con­
d itions. Summer tires hand le better when
there is no snow or ice on the roads and the
temperature is above 45
°F (7 °().
If yo u have a flat tire, see notes on spare

speed rat ing letter codes and the maximum
speed at wh ich the t ires can be driven .
The speed rating letter code( ¢ page 232) is

A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed. Always know the maximum
speed befo re driving off . Never drive faster
than the speed permitted for your specific
w inte r tir es . This will cause damage to the
ti res leading to an ac cident and se rious
pe rsonal i njury to you and yo ur p assen­
gers .

A WARNING
Driving faster than the maximum speed
for which the winter tires on your ve hicle
were designed can cause t ire fail ure in­
cluding a blowout and sudden deflation,

A WARNING
=
A lways ad just yo ur driving to t he roa d and
traffic conditions. Never let the good ac­
celeration of the winter tires and a ll wheel
drive tempt you into taking extra risks. Al­
ways remember:
- When braking, an all wheel drive vehicle handles in the same way as a front drive
veh icle.
- Drive carefully and reduce your speed on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions.
@ For the sake of the environment
Use summer tires when weather condi­
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
-
Snow cha ins may be fitted only to the fro nt
whee ls, and on ly to certain tire sizes . Ask your
autho rized Aud i dea le r o n whi ch tire sizes
snow chains can be used.
The snow chains must have low-p rofile links
and must not be th icker than

and handling under a variety of driving condi­
tions . Ask your authorized Audi dealer for
more details.
The low aspect ratio of these tires is indicated
by a numeral of
55 or less in the tire's size
designation. The numeral represents the ratio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage . Conven­
tional tires have a height/width ratio of 60 or
more .
The performance of low-aspect-ratio tires is
particularly sensitive to improper inflation
pressure. 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 pres­
sures should be checked at least once a
month and always before a long trip
¢ page 239, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact with potho les, curbs, gullies
or ridges on the road, particularly if the tire is
underinflated .
In order to minimize the occurrence of impa ct
damage to the tires of your vehicle, we recom­
mend that you observe the following precau­
tions:
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add air if neces­
sary .
- Drive carefully on roads with potholes, deep
gullies or ridges. The impact from driving
t hr ough or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
t ir es or have them inspected by the nearest
authorized Aud i dealer. Replace a damaged
t ir e as soo n as possible .
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see . Damage can lead to loss of
air and underinflation, wh ich could eventu-
Tires and wheels 257
ally cause tire failure. If you believe that a
tire may have been damaged, rep lace the
tire as soon as possib le.
- These tires may wear more quickly than oth­
ers.
- Please also remembe r that, while these tires
deliver responsive handling, they may ride
less comfortably and make more noise than
other choices.
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance
tires or iginally installed on your vehicle are in­
tended for maximum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy o r icy weather conditions. If
you drive under those circumstances, you
should equip your vehi cle w ith all-season or
winter tires, which offer better traction under
those conditions. We suggest you use the rec ­
ommended snow or a ll-season tires specified
for your vehicle, or their equivalent .
Refer to¢
page 254 for more detailed infor­
mation regarding winter tires.
Ti re pressure
monitoring system
ill General notes
Applies to vehicles: with tire pressure monitoring system
Each tire, including the spare (if provided),
sho uld be checked monthly when cold and in ­
flated to the inflation pressure recommended by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a d ifferent size than the
s ize indicated on the vehicle placard or tire in ­
flat io n pressure label, you should determine
the proper t ire inflation pressu re for those
tires).
As an added safety feature , your veh icle has
been equipped with a tire pressure mon itoring
system (TPMS) that illum inates a low ti re
pressure te llt ale when one or more of your
tires is significantly under-inflated. .,.

.&, WARNING
- If the t ire pressure indicator appears in
the instrument cl uster d isplay, one or
more o f your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle 's t ire
pressure label~
page 234 . Driving on a
significantly under-inflated tire ca uses
the tire to overhea t and can lead to tire
failure. Under-inflation also is likely to impair the vehicle 's handling and stop ­
ping ability.
- The driver is responsible for mainta ining
the correct tire pressures. You must check the tire pressures regularly .
- Under certain cond itions (such as a spor ­
ty driving style, winter conditions or un­ paved roads), the pressure monitor indi­
cator may be de layed .

-Ask your a uthorized Audi dea ler if run­
flat tires may be used on your vehicle.
(D Tips
- The tire pressure mon itoring system may
stop working when there is an ESC ma l­
function.
- Using snow chains may res ult in a system
ma lfunction.
- The tire pressure mon itor ing system on
your Audi was deve loped using tires with
the "AO" or "RO" identification on the

mend us ing these tires.
Reset tire pressure monitoring system
App lies to vehicles: with tire pressure mon itor ing system
If the tire pressure is adjusted, wheels ore ro­
