Tire
damage
General
information
Inspect
your
tires
regularly
for
damage,
foreign
objects
lodged
in
the
tread,
and
tread
wear.
Driving
over
rough
or
damaged
road
surfaces,
aswell
as
debris,
curbs
and
other
obstacles
cancause
serious
damage
to
wheels,
tires
and
sus#j
pension
parts.
This
is
more
likely
to
occur
with low-profile
tires,
which
provide
less
cushioning
between
the
wheel
and
the
road.
Be
careful
to
avoid
road
hazards
and
reduce
your
speed,
es#j
pecially
if
your
vehicle
is
equipped
with
low-pro#j file
tires.
Indications
of
tire
damage
or
other
vehicle
mal#j
functions:
'xUnusual
vibrations.'xUnusual
tire
or
running
noises.'xUnusual
handling
such
as
a
strong
tendency
to
pull
to
the
left
or
right.
Damage
can
be
caused
by
the
following
situa#j
tions,
for
instance:
'xDriving
over
curbs.'xRoad
damage.'xTire
inflation
pressure
too
low.'xVehicle
overloading.'xIncorrect
tire
storage.
Safety
information
Warning
Damaged
tires
can
lose
tire
inflation
pressure,
which
can
lead
to
loss
of
vehicle
control.
There is
a
risk
of
accident.
If
tire
damage
is
suspected
while
driving,
immediately
reduce
speed
and
stop.
Have
wheels
and
tires
checked.
For
this
purpose,
drive
carefully
to
the
nearest
dealer#ss
service
center
or
another
qualified
service
cen#j
ter
or

Warning
Tires
can
become
damaged
by
driving
over

If
possi#j
ble,
avoid
driving
over

Safety
information
Warning
Wheels
and
tires
which
are
not
suitable
for
your
vehicle
can
damage
parts
of
the
vehicle,
for
in#j stance
due
to
contact
with
the
body
due
to
tol#jerances
despite
the
same
official
size
rating.
There
is
a
risk
of
an
accident.
The
manufac#j turer
of
your

and
tires
that
have
been
recom#j
mended
by

manufacturer
for
your
vehicle
type.
Warning
Mounted
steel
wheels

discs.
There
is
a
risk
of

of
systems,
such
as
the
ABS

type.
Following
tire
damage,
have

information
Winter
tires
are
recommended
for
operating
on winter
roads.
Although
so-called
all-season
M+S
