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.

Your vehicle is equipped with a tire repair kit,
the
Tire Mobility System (TMS)*.
In the event of a tire fa ilu re, the TMS is in the
l uggage compartment under the floor.
It con ­
sists of the tire sea lant and an electric a ir
pump .
Using
TMS , tire damage caused by foreign
bod ies up to abou t
0.16 inch (4 mm) in diam­
eter can be sealed reliab ly.
The foreign object can stay in the t ire.
The tire sealant must not be used:
-for cuts or punctures in the tire which are
larger than 0.16 inch (4 mm)
c> fig. 159 (D
- for damage to the rim@
- if you have been driving with very low tire
pressures or tires with no air @
Using the
TMS is desc ribed in the section
c> page 220, Preliminary steps.
TMS can be used at temperatures dow n to -
4 °F (- 20 °().
A WARNING
Take the following precautions after re ­
pairing the tire:
-
- Do not drive faster than 50 mph (80 km/
h)!
- Avoid full-throttle acce le rat ion, heavy
braking and fast cornering.
- T he veh icle's road behavior can be affect­
ed.
- T ires sealed with
TMS a re intended only
for
temporary, short-term use.
- After using the tir e sea lant the tire pres­
sure monitoring system may no longer
work prope rly. Drive carefully to the next
professional repair facility .
-TMS mus t NOT be used,
- for cuts or punctures in the tire which are larger than 0.16 inch (4 mm)
- for damage to the rim
- if you have been driving with very low
tire pressures or tires with no air
What do I do now? 219
-Seek professional assistance if it is not
possible to repa ir the tire w ith the t ire
sealant.
A WARNING
The tire sealant must not come into con­
tact with skin, eyes or clothing.
- If you get any tire sealant in your eyes or
come into contact w ith it, rinse the af­
fected area thoroughly with clean water .
Find a phys ician immediately!
- Change any clothing contaminated with
tire sealant immediately.
- Do not inha le the vapor!
- If you have swallowed tire sealant, rinse
your mouth thoroughly right away and
drink plenty of water.
- Do not induce vomiting! Find a physi­
c ian i mmediately!
- If you have allergic react ions, find a
phys ician immediately.
- Keep the tire sealant away from children.
(D Note
Do not use commercially availab le tire
sealants . The electr ical components of the
tire pressure monitoring system will no
l onge r work properly.
@ For the sake of the environment
Used sealant bottles can be dropped off at
a recycling facility .
@ Tips
-If sea lant has run out, allow it to dry.
Then you can peel it off.
- Have the tire sealant replaced every 4
years at a dealership .
