T i re s and w heel s
Run-flat tires have special characteristics
and requirements, that are very different
from conventiona l t ires. Run-flat tires re-
quire special rims for run-flat use and can-
not be used on conventional wheel rims .

Tips
- If you are not able to continue driving
with run-flat tires, please seek profess io-
nal assistance .
- Please contact your authorized Audi
dealer or Audi of America, Inc. if you
have quest ions about tires and rims.
Driving with run-flat tires
App lies to vehicles: with Run-flat tires
Handling characteristics change when tire
pressure is low.
Driving on tires w ith low t ire 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 st ill take special precaut ions when oper-
ating a vehicle on run-flat t ires w hen tire pres-
sure is low or the t ire(s) is f lat:
"' The Electron ic Stabilization Program (ESP)
must be switched on.
>
Never dr ive faste r than 50 mph (80 km/h)
¢ ,& .
"' Plan ahead when driving and anticipate
what you will have to do considering traffic
and road condit ions up ahead.
"' Accelerate carefu lly.
"' Avoid unnecessary and sudden steer ing and
braking maneuvers .
"' Reduce your speed in plenty of time before
intersections, curves and othe r places w here
you may have t o react quickly.

ble to continue driving, even with run-flat
tires?
Handling characteristics change when
driving with low air pressure or with flat
tire s even with special run-flat tires
A low pressure or flat front tire affects vehicle
handling characterist ics by pull ing the vehicle
slightly to the side whe re the tire is mounted
and reduces braking performance .
A low pressure or fla t rear tire also affects
driv ing characteristics by pulling to the side
whe re the t ire is mounted and also reduces
braking performance . The effect on vehicle
handling is most noticeab le when driving
around curves.

WARNING
Changed vehicle hand li ng characterist ics
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 maximum
rated speed of 50 mph (80 km/h) whe n
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 ions
are taken into account.
- Always obey speed limits and othe r traf-
f ic laws.

Note
We always recommend driving with even
more care when using these special tires in
the run-flat mode. Always avoid sudden
maneuvers.
