Introduction
Run-flat tires help keep you moving if a tire goes flat.
Reinforced sidewalls give the tires run -flat capability if t ire pressure
is lost
.
We recommend that run -flat tires only be mounted on vehicles that
were origina lly equipped with these special tires at the factory and
have a Tire Pressure
M
onitoring System.
Run-flat tire
s
can be identified by
t
he letter
s "RSC"
on the tire
side-
wa
ll.
If you do change the tires on you
r
vehicle from normal
t
o run -flat
tires
,
you must buy the special rims required for run -flat tires, and
the
T
ire Pressure
M
on itoring System must be reprogrammed
by an
authorized Audi dea ler or other qual ified workshop.
