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,
as
well
as
debris,
curbs
and
other
obstacles
can
cause
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
repair
shop.
Have
vehicle
towed
or
trans#j ported
as
needed.
Do
not
repair
damaged
tires,
but
have
them
replaced.
Warning
Tires
can
become
damaged
by
driving
over
ob#j
stacles,
e.g.,
curbs
or
road
damage,
at
high
speed.
Larger
wheels
have
a
smaller
tire
cross- section.
The
smaller
the
tire
cross-section,
the
higher
the
risk
of
tire
damage.
There
is
a
dan#j
ger
of
accidents
and
property
damage.
If
possi#j
ble,
