also
use
all
season
tires
instead
of
winter

that
in
some
coun-
tries
where
winter
tires
are
required,
only
win-
ter
tires
with
the

ted.
Snow

road
conditions.
>
Only

>
Check
and
correct
the
seating
of
the
snow
chains
after
driving
a
few

if
necessary.
Fol-
low

instructions
from
the
manufacturer.
>
Note
the
maximum
speed
of
30
mph
(50
km/h).
Observe
the
local
regulations.
Use
of
snow
chains
is
only
permitted
with
certain
rim/tire
combinations
due
to
technical
reasons.
Check
with
an
authorized
Audi
dealer
or
author-
ized
Audi
Service
Facility
to
see
if
you
may
use
snow
chains.
Use
fine-mesh
snow
chains.
They
must
not
add
more
than 0.53
in
(13.5
mm)
in
height,
including
the
chain
lock.
You
must
remove
the
snow
chains
on
roads
with-
out
snow.
Otherwise,
you
could
impair
driving
ability
and
damage
the

WARNING
Using
incorrect
snow
chains
or
installing

of
an
acci-
dent.

Low-profile
tires
Applies
to:
vehicles
with
low-profile
tires
Compared
to
other
tire/rim
combinations,
low-
profile
tires
offer
a
wider
tread
surface
anda
larger
rim
diameter
with
shorter
tire
sidewalls.
This
results
in
an
agile
driving
style.
However,
it
may
reduce
the
level
of
comfort
and
increase
road noise
when
driving
on
roads
in
poor
condi-
tion.
Low-profile
tires
can
become
damaged
more
quickly
than
standard
tires
when
driving over
large
bumps,
potholes,
manhole
covers,
and
curbs.
Therefore,
it
is
particularly
important
to
maintain
the
correct
tire
pressure
>
page
245.
To
reduce
the
risk
of
damage
to
the
tires
and
rims, drive
very
carefully
on
poor
roads.
Check
your
wheels
regularly
every
2,000
mi
(3,000
km)
for
damage.
For
example,
check
for
bulges/cracks
on
the
tires
or
deformations/cracks
on
the rims.
After
a
heavy
impact
or
damage,
have
the
tires
and
rims
inspected
or
replaced
immediately
by
an
authorized
Audi
dealer
or
authorized
Audi
Service
Facility.
Low-profile
tires
can
wear
out
faster
than
stand-
ard
tires.
