Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio t ires. These t ires have been thorough ly
tes ted and been selected spec ifica lly for your
model for the ir superb pe rformance, road feel
and handling under a variety of driving condi­
tions . Ask your a uthorized Audi dea le r for
more deta ils.
The low aspect ratio of these tires is indicated
by a numeral of
55 or le ss in the tire's size
designation. The numeral represents the ratio
of the tire's sidewall height in relat ion to its
tread width expressed in percentage . Conven­
tional tires have a height/width ratio of 60 or more .

What you can do to avoid tire and rim
damag e
Low aspec t ratio t ires can be damaged more
easi ly by impact with potho les, cu rbs, gu llies
or ridges on the road, part icu larly if the tire is
underinflated .
I n o rder to m inimize the occu rrence o f impact
damage to the t ires of your vehicle, we recom -
Tires an d wheel s 211
mend that you observe the following preca u­
tions:
- Always ma inta in re commended inflation
pressures . Check your tire pressu re eve ry
2,000 miles (3,000 km) and add air if neces ­
sary.
- Drive caref ully on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires .
- After any impact, immediate ly inspect your
tires or have them inspected by the nearest
au thor ized 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 no t al­
ways easy to see . Damage can lead to loss of
air and under inflat ion, which could eventu­
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 tha n oth­
ers.
- Please also remember that, while these tires
de live r responsive handling, they may ride
less comfo rtably and make more noise than
other choices .
Reduced performanc e in winter /cold
season conditions
A ll ti res are designed for certa in p urposes.
T he low aspect ratio, ult ra h igh performance
tires originally installed on your vehicle are in­
tended for maxim um dry and wet road per­
formance and handling. They are not suitable
for cold , snowy or icy weather condi tions. If
you drive under those circumstances, you
should equ ip your vehicle w ith all-season or
winter tires, which offer bette r traction under
those conditions. We suggest you use the rec­
ommended snow o r all-season t ires specified
f o r yo ur vehicle , or thei r equivalent .

212 Tires and wheels
Tire pressure
monitoring system
General notes
Appl ies to vehicles: with tire pressure monitoring system
Each tire, including the spare (if provided),
should be checked monthly when cold and in­
f lated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has t ires of a different size than the
size indicated on the vehicle placard or tire in­
flation pressure label, you should determine
the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you should stop and check your tires as
soon as possible, and inflate them to the proper pressure. Driving on a significantly un­
der-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation al­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv­
er's responsib ility to ma inta in correct tire
pressure , even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indicate when
the system is not operating properly. The
TPMS malfunction indicato r is combined with
the low tire pressure telltale. When the sys­
tem detects a malfunction, the telltale will
f lash for approximately one minute and then
remain continuously illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction exists. When the
malfunction indicator is illuminat­
ed, the system may not be ab le to detect or
s ignal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­
ment or alternate tires or wheels on the vehi­
cle 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 ens ure that the re­
placement or alternate ti res and wheels allow
the TPMS to continue to function properly.

Run-flat tires
Introduction
Applies to vehicles: with Run-flat tires
Run-flat tires help keep you moving if a tire
goes flat.
Reinforced s idewalls give the tires run-flat ca­
pability if tire pressure is lost.
We recommend that run-flat tires only be
mounted on vehicles that were originally
equ ipped w ith these special tires at the facto­
ry and have a Tire Pressure Monitor ing Sys­
tem.
Run-flat t ires can be ident ifi ed by th e lett ers
"RSC" on the tire sidewall.
If you do change the tires on yo ur vehicle from
normal to run-flat tires, you must buy the
specia l rims required for run-flat tires, and the
Ti re Pressure Monito ring System must be re­
programmed by an a uthorized Audi dea ler or
other qualified workshop.
What do run-flat tires do?
These special tires have run-flat capabilities
that help keep you moving if a tire loses pres­
sure and goes flat. Under favorable cond itions
tires can be driven
at l ea st 30 mil es (SO km ),
but you must not d rive fa ste r than SO mph
(80 km /h)
c::;, page 216, Driving with run-flat
tires .
Tire s an d wheel s 215
When it is not po ssible to continue
driv ing , ev en with run-flat tire s?
- If the Electronic Stabilization Program (ESP)
is not work ing or keeps coming on.
- If the Tire Pressure Monitoring System does
not work.
- If the tire has been severely damaged, in a
crash, for example. The tread can separate
from a damaged tire as the wheel turns, and
hit parts of the vehicle, such as the fuel tank
filler neck, fuel lines or brake lines.
- Do not continue driving if severe vibration
occurs or if the t ire starts to smoke because
the tire is ru nning hot.
- Do not continue driving if damage to the
tire, such as cracks in the sidewall, appears.
A WARNING
Improper use of run-flat tires can cause
vehicle damage that can lead to loss of ve­ h icl e cont ro l, a c rash and serious personal
in Jury.
- Run-flat tires can only be used with spe­
cial rims.
- Run-flat tires must always be monito red
with a prope rly p rogrammed Tire Pre­
ssure Monito ring System.
- Always inspect a tire that has lost air to
make sure it is sa fe to dr ive with the tire
in the run-flat mode.
- Never d rive with run-f lat t ires that have
been damaged in a co llision.
- Never d rive with run-flat t ires if heat
bu ild-up causes the tire to give off
smoke.
- Never d rive with run-f lat t ires if the vehi­
cle shakes or vibrates severely.
- Never d rive with a run-flat ti re that de­
velops s idewa ll cracks or other damage
while in use.
- I f you sw itch between standa rd and run­
f lat ti res, an aut horiz ed Aud i dealer o r
qu alified wor kshop must reprogram the
con tro l mod ule.

216 Tires and wheels
Run-flat tires have special characteristics
and requirements, that are very different
from conventiona l tires. Run-flat tires re­
quire special rims for run-flat use and can­
not be used on conventional wheel rims.
(D Tips
- If you are not able to continue driving
with run-flat tires, please seek professio­
nal assistance .
- Please contact your authorized Audi
dealer or Audi of America, Inc. if you
have questions about tires and r ims.
Driving with run-flat tires
App lies to vehicles: with Run -flat tires
Handling characteristics change when tire
pressure is low .
Driving on tires with low tire pressure changes
the way a vehicle handles, particularly when
cornering and braking . The handling charac­
teristics of run-flat tires do not seem to
change a lot even when dr iving on low pres­
sure or in the run-flat mode . Nevertheless you
must still take special precautions when oper­
ating a vehicle on run-flat tires when tire pres­
sure is low or the tire(s) is fla t:
"'The Electronic Stabilization Program (ESP)
must be switched on.
> Never drive faste r than 50 mph (80 km/h)
¢,& .
"'Plan ahead when driving and anticipate
what you will have to do considering traffic
and road conditions up ahead.
"' Accelerate carefully.
"' Avoid unnecessary and sudden steer ing and
braking maneuvers .
"' Reduce your speed in plenty of time before
i ntersections, curves and other places where
you may have to react quickly.
Please see:
¢ page 215, When it is not possi­
ble to continue driving, even with run-flat
tires?
Handling characteristics change when
driving with low air pressure or with flat
tires even with special run-flat tires
A low pressure or flat front tire affects vehicle
handling characterist ics by pulling the vehicle
slightly to the side whe re the tire is mounted
and reduces braking performance .
A low pressure or flat
rear tire also affects
driving characteristics by pulling to the s ide
where the tire is mounted and also reduces
braking performance . The effect on vehicle
handling is most noticeable when driving
aro und curves .
A WARNING
Changed vehicle hand ling characteristics
when driving in the run-flat mode can
cause loss of vehicle control, a crash and
serious personal injury.
- Driving on special run-flat tires in the
run-flat mode will change vehicle han­
dling characterist ics dur ing braking,
when cornering and under heavy acceler­
ation .
- Never drive faster than the max imum
rated speed of 50 mph (80 km/h) when
driving in the run-flat mode.
- Always adjust vehicle speed to traff ic,
road and weather conditions and drive
slower than the maximum rated speed if
necessary weathe r and road cond it ion s
are taken into account.
- Always obey speed limits and other traf­
f ic laws.
(D Note
We always recommend driving with even
more care when using these special tires in
the run-flat mode. Always avoid sudden
maneuve rs.

Replacing run-flat tires and rims
Appl ies to vehicles: with Run -flat tires
Your vehicle was especially designed to use
special run-flat tires .
You may use and combine only approved run­
flat t ires and spec ial matching rims that have
been designed for run -flat tires. Mount ing
special run-flat t ires on standard wheels will
not work and will not provide the advantages
fo the run-falt featu re. Neve r use specia l run­
flat t ires on standard wheel rims .
After driving with a tire in the run-flat mode,
a lways have the vehicle and affected tire(s)
and rim(s) inspected by an autho rized Aud i
dealer . T ir es that have been driven in the run­
flat mode must be replaced.
A WARNING
Use of damaged run-flat tires and rims can
cause vehicle damage that can lead to loss
o f vehicle control, a crash and ser ious per­
sonal injury.
- Always have the veh icle and affected
t ire(s) and rim(s) inspected by an author­
ized Audi dealer after driving a t ire in the
run-f lat mode.
- Tires that have been driven in the run­
flat mode must be rep laced.
