and
tread
wear.
Driving
over
rough
or

surfaces,
as
well
as
debris,
curbs
and
other
obstacles
can
cause
serious
damage
to
wheels,
tires
and
susj
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,
esj
pecially
if
your
vehicle
is
equipped
with
low-proj file
tires.
Indications
of
tire
damage
or
other
vehicle
malj
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
situaj
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

replaced.
Warning
Tires
can
become
damaged
by
driving
over
obj
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
danj
ger
of
accidents
and
property
damage.
If
possij
ble,
avoid
driving
over
objects
or
road
condij
