TemperatureThe
temperature
grades
are
A,
the
highest,
B,
and
C,
representing

and
its

to
dissipate
heat when

under
controlled
conditions
on

Sustained
high
temperature
can
cause
the
material
of
the

to

and
reduce
tire

and
exces#j sive

can
lead
to
sudden
tire

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.

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

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

ger
of
accidents
and

damage.
If
possi#j
ble,
avoid
driving
over
