& WARNING
• Using incorrect or unmatched 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 specifica­
tions of original factory -installed tires or other combinations that
have been spe cifically approved by the vehicle manufacturer.
• 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 vehi cle if you are not sure of
their "previous history. " Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehi cle control.
& WARNING (continued)
• All four wheels must be fitted with radial tires of the same type,
size (rolling circumference ) and the same tread pattern. Driving
with different tires reduces vehicle 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 e xample 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 faste r than
their rated speed can fail suddenly .
• Overloading tires cause heat build-up , sudden tire failure ,
including a blowout and sudden deflation and loss of control .
• Temperature grades apply to tires that are properly inflated and
not over or underinflated .
• For te chnical reasons it is not always possible to use wheels
from other vehicles -in some cases not even wheels from the
same vehicle model.
• If you install wheel trim discs on the vehicle wheels, make sure
that the air flow to the brakes is not blocked. Redu ced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision.
• Run flat tires may only be used on vehicles that were equipped
with them at the fa ctory . The vehicle must have a chassis designed
for run flat tires and a factory -installed tire pressure monitoring
system that indi cate s a loss of tire pressure . Incorre ct use of run
flat tires can lead to vehicle damage or accidents . Check with an
authorized Audi dealer o r tire specialist to see if your vehicle can
be equipped with run flat tires .
If run flat tires are used, they must
be installed on all four wheels . Mixing tire types is not permitted. .,

•
• After any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a
damaged tire as soon as possible .
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see. Damage can lead to loss of
air and underinflation, which could eventua lly cause tire fai lure . If
you believe that a tire may have been damaged, replace the tire as
soon as possible .
• These tires may wear more quickly than others.
• Please a lso remember that, whi le these tires deliver responsive
handling, they may ride less comfortably and make more noise than
other choices.

co nditi ons
All tires are designed for certain purposes. The low aspect ratio,
ultra high performance tires originally installed on your vehicle are
intended for maximum dry and wet road performance and hand ling.
They are not suitable for cold, snowy or icy weather conditions . If
you drive under those circumstances, you should equip your vehicle
with al l- season or winter tires, which offer better traction under
those conditions . We suggest you use the recommended snow or
a ll- season tires specified for your vehicle, or their equivalent .
Refer to=>
page 254 for more detai led in formation regarding winter
tires. •
Run-flat tires
Applies to vehi cles : w ith R un-f lat tires
Introduction
Run-flat tires help keep you moving if a tire goes flat.
Reinforced s idewalls give the ti res run -flat capability if tire pressure
is lost . We recommend that run-flat tires only be mounted on vehicles that
we
re origina lly equipped with these special tires at the fac tory and
have a Tire Pressure Monitoring System .
Run-flat t ires can be ident ified by the letter s "RSC" on the tire side ­
wall.
If you do change the tires on your vehic le from normal to run -flat
tires, you must buy the special rims required for run-flat tires, and
the Tire Pressure Monitoring System must be reprogrammed by an
authorized Audi dea ler or other qualified workshop.
Wh at do run-fl at tir es do?
These special t ires have run-flat capabi lities that he lp keep you
moving if a tire loses pressure and goes flat. Under favorable condi ­
t ions tires can be driven
at least 30 miles (50 km ), but you must not
drive
f as ter t han 50 mph (80 km/h i=> page 258 , "Driving with run ­
flat t ires".
The Tire Pressure Moni toring System constantly checks the air pres­
sure in the tires. If the run -flat system is active (shown in the center
display), you must inspect the affected tire or tires and then decide
whether to continue driving . Be sure to follow these tips
=>
page 258, "Driving with run-flat tires" .
When it is not po ssibl e to continue driving , even with
run -fl at tire s?
• If the Electronic Stabilization Program (ES P) is not working 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 fue l 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 s idewall, appears .

-Tires and wheels
---------------------------------------------
& WARNING
Improper use of run-flat tires can cause vehicle damage that can
lead to loss of vehicle control, a crash and serious personal injury.
• Run-flat tires can only be used with special rims.
• Run -flat tires must always be monitored with a properly
programmed Tire Pressure Monitoring System.
• Always inspect a tire that has lost air to make sure it is safe to
drive with the tire 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 vehicle shakes or vibrates
severely.
• Never drive with a run-flat tire that develops sidewall cracks or
other damage while in use.
0 Note
Run -flat tires have special characteristics and requirements, that are
very different from conventional tires . Run-flat tires require special
rims for run -flat use and cannot be used on conventional wheel
rims .
[ i] Tips
• If you are not able to continue driving with run-flat tires, please
seek professional assistance.
• Please contact your authorized Audi dealer or Audi of America,
Inc. if you have questions about tires and rims. •
Applie s t o vehic le s: wi th Run -flat tires
Driving 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, particularl y when cornering and braking.
The handling characteristics of run-flat tires do not seem to
change a lot even when driving on low pressure or in the
run -flat mode . Nevertheless you must still take special
precautions when operating a vehicle on run-flat tires when
tire pressure is low o r the tire(s) is flat:
- The Electronic Stabilization Program (ESP) must be
switched on.
- Never drive faster 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.
- Avo id unnecessary and sudden steering and braking
maneuvers .
- Reduce your speed in plenty of time before intersections,
curves and other places where you may have to react
quickly.

Handling characteristi cs change wh en dri ving with
low air pressure or with flat tires even with special run ­
flat tires
A low pressure or flat front tire affects vehicle hand lin g charac te ri s­
t ics by pulling the vehic le slightly to the side where the tire is
mounted and reduces brak ing performance .
A low pressure or flat
rear tire also affec ts driving c haracteristics by
pul ling to the side where th e tire is mounted and also reduces
b raki ng per for mance . T he ef fec t o n ve hic le han dlin g is most n otice ­
able when driving around curves .
& WARNING
Changed vehicle handling characteristics when driv ing in the run­
flat mode can cause lo ss of vehicle control , a crash and serious
personal injury .
• Driving on special run-flat tires in the run -flat mode will change
vehicle handling characterist ics during braki ng , when cornering
and under heavy acceleration .
• 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 traffic , road and weather condi­
tions and drive slower than the maximum rated speed if nece ssary
weather and road conditions are taken into ac count .
• Always obey speed limits and other traffic laws .
0 Note
We always recommend driv ing with even more care when using
these special tires in the run -flat mode. A lways avoid sudden
m aneuvers. •
