2013 AUDI TT tire pressure

216 Tires and wheels
Inflate the tire pressure to the proper
pressure as indicated on the vehicle's tire
pressure label¢
page 200. Driving on a
significantly under-inflated tire causes
the tire to overheat 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 maintaining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor ind i­
cator may be delayed.
- Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle .
Your vehicle registration becomes invalid
if you use these tires when not permit­
ted. Damage to your veh icle or accidents
could also result.
- If you switch between standard and run­
flat tires, an authorized Audi dealer or
qualified workshop must reprogram the
control module .
@ Tips
-The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction .
- The tire pressure monitoring system on
your Audi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall ¢
page 207. We recom­
mend using these tir es.

Run-flat tires
Introduction
Applies to vehicles: wit h Run-fla t tires
Run-flat tires help keep you moving if a tire
goes flat.
Re inforced sidewalls give the t ires r un-flat ca­
pabili ty if tire pressure is lost .
We recommend that run-flat tires o nly be
mounted on vehicles that were orig inally
equipped with these special t ires at the facto­
ry an d have a Tire Pressu re Monitoring Sys­
tem .
Run-flat tir es can be identifi ed by th e letters
"RSC" on the tire sidewall.
If you do change the tires on your veh icle from
no rma l to run-flat tires, you must buy the
special rims required fo r run-flat tires, and the
T ire Pressu re M on itor ing System must be re­
programmed by an authorized Aud i d ealer o r
othe r qualified wo rkshop .
What do run -flat tires do?
These special tir es have run-flat capab ilities
that help keep you moving if a tire loses pres­
s ur e and goes flat. Under favorab le condi tions
t ir es can be dr iven
at least 30 miles (SO km) ,
but you mus t not drive fa ster than SO mph
( 80 km/h)

tires .
Ill-

218 Tires and wheels
When it is not possible to continue
driving , even with run-flat tires?
-If the E lectronic Stabilization Control (ESC)
is not working or keeps coming on.
- If the
Tire Pr essure 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 tire starts to smoke because
the tire is running 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
hicle control, a crash and serious personal
lnJUry.
- Run-flat tires can only be used with spe­
cial rims.
- Run-flat tires must always be mon itored
with a properly programmed Tire Pre­
ssu re Monit oring Sys tem.
- Always inspect a tire that has lost air to
make sure it is safe to drive with the tir e
in the run-flat mode.
- Never drive with run-flat tires that have
been damaged in a collision.
- Never drive with run-flat tires if heat
build-up causes the tire to give off
smoke.
- Never drive with run-flat tires if the vehi­
cle shakes or vibrates severely.
- Never drive with a run-flat tire that de­
velops sidewall cracks or other damage
wh ile in use .
-If you switch between standard and run­
flat tires, an authorized Audi dealer or
qualified workshop must reprogram the
control module.
(D Note
Run-flat tires have specia l characteristics
and requirements, that are very different
from conventional 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 cont inue driv ing
w ith 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 rims .
Driving with run-flat tires
Applies to vehicles: wit h Run -flat tires
Handling characteristics change when tire
pressure is low .
Driving on tires with low tire pressure changes
the way a veh icle handles, particularly when
cornering and braking. The handling charac­
teristics of run-flat tires do not seem to
change a lot even when driving on low pres­
sure or in the run-flat mode . Nevertheless you
must still take spec ia l precautions when oper­
at ing a vehicle on run-flat tires when tire pres­
sure is low o r the tire(s) is flat:
.,. Th e Electronic Stabilization Control (ESC)
must be switched on.
.,. Never drive faster than SO mph (80 km/h)
q &_ .
.,. Plan ahead when driving and anticipate
what you will have to do considering traffic
and road conditions up ahead .
.,. Accelerate carefully.
.,. Avo id unnecessary and sudden steering and
brak ing maneuvers .
.,. Reduce your speed in plenty of time before
intersections, curves and other places where
you may have to react qu ickly.
Please see:
qpage 218, 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 characteristics by pu lling the vehicle
slightly to the side where the tire is mounted
and reduces braking performance .
A low pressure or flat
rear tire also affects
driving character istics by pulling to the side
where the tire is mounted and also reduces
brak ing performance. The effect on vehicle
handling is most not iceable when driving
around curves.
A WARNING
Changed vehicle handling character istics
when driving in the run -f lat mode can
cause loss of vehicle contro l, a crash and
serious personal injury.
- Driving on special run-flat tires in the
run-f lat mode wi ll change vehicle han­
dling characteristics during braking,
when cornering and under heavy acceler­
ation.
- Never drive faster than the maximum
rated speed of 50 mph (80 km/h) when
dr iv ing in the run -flat mode.
- Always adjust vehicle speed to traffic,
road and weather cond itions and drive
slower than the max imum rated speed if
necessary weather and road conditions
are taken into account.
- Always obey speed limits and other traf­
fic laws.
Q) Note
We always recommend driving w ith even
more care when using these special t ires in
the run-flat mode . Always avo id sudden
maneuvers.

Replacing run-flat tires and rims
App lies to veh icles : w it h Run -flat t ires
Your vehicle was especially designed to use
special run-flat tires.
You may use and combine only approved run­
flat tires and special matching rims that have
been designed for run-flat tires . Mounting
special run-flat tires on standard wheels will not work and w ill not prov ide the advantages
fo the ru n-falt feature . Never use spec ial run­
flat tires on standa rd wheel rims.
After dr iving with a tire i n the run-flat mode,
always have the vehicle and affected tire(s)
and rim(s) inspected by a n authorized Audi
dealer. Tires that have been driven in the run­
f lat mode must be rep laced .
A WARNING
-Use of damaged run-flat tires and rims can
cause vehicle damage that can lead to loss
of vehicle control, a crash and serious per­
sonal injury.
- Always have the vehicle and affected
tire(s) and r im(s) inspected by an author­
ized Audi dealer after driving a tire in the
run-flat mode .
- Tires that have been dr iven in the run­
flat mode must be replaced.

then you can peel it off.
Final check
App lies to vehicles: wit h Tire Mobility System
After driving for a short distance, tire
pressure must be checked
~ After d riving for about 10 m inutes, stop
and check the tire pressure.
~ If tire pressure is still at leas t 1.3 bar, in­
flate the tire to specified pressure (see driv­
ers side B -pillar), drive to the next repair
shop and have the tire and the sealant bot­
tle replaced.
~ If tire pressure is less than 1.3 bar, the t ire
is too severely damaged. Do not cont inue to
drive . Seek professional assistance.
A WARNING
If t ire pressure is less than 1.3 bar after
driving for 10 minutes, the tire is too se­
ve rely damaged. Do not continue to drive.

Notes on wheel change
Pl ease rea d the information ¢ page 207, New
tires and replacing tires and wheels,
i f you are
going to use a spare t ire which is different
from the tires on your ve hicle.
Afte r you change a tire:
- Check the tire pressure on the spare imme ­
diately after mounting .
- Have the wheel bolt tightening torque
che cked with a torque wrench as soon as
possible by your authorized Audi dealer or
a qualified service station.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of
90 ft lb (120 Nm) .
- If you notice while changing a tire that the
wheel bolt s are co rroded and diffi cult to
turn , then they should be replaced before
you check the t ightening torque.
What do I do now? 227
- Replace the flat tire with a new one and
have it installed on your vehicle as soon as
possible. Remount the wheel cover .
Until then , drive with extra care and at re­
duced speeds.
A WARNING
-
- If you are go ing to e quip your ve hicl e
wit h tires o r rims which differ from those
which were factory installed, t hen be
sure to read the information¢
page 207,
New tires and replacing tires and

forwa rd, causi ng injury to passe ngers in
the vehicle.
Tires with unidirectional tread design
Tires with unidirectional tr ead design must be
mounted with their tread pattern pointed the
right dire ction.
A u nidirectional tire can be identified by ar­
rows on the sidewall,
which point in the direc ­
tion of t he rota tion. Yo u m ust follow the
s p ecifie d direction of rot ation. This i s nece ssa ­
r y in order fo r these tires to develop t heir op­
timum character istics regard ing grip, road
no ise, wear, and hydrop la ning.
