failure.Thegrade
C
corresponds
to
a
level
of performance which
all
passenger car tires must meet under the Federal Motor Vehicle Safety
Standard
No.
109.
Grades
B
and
A
represent higher
levels
of performance
on
the
laboratory
test wheel
than
the minimum required by
law.
Warning:Thetemperaturegradeforthistireisestablishedforatirethat
is
properly
inflated and not overloaded. Excessive speed, underinflation, or
excessiveloading,eitherseparatelyor
in combination, can cause
heat buildup
and possible tire failure.
These grades are molded on
the sidewalls of passenger car
tires.
While
the
tires available as standard or optional equipment on General Motors
vehicles may vary
withrespect
to
these grades,
all suchtiresmeetGeneral
Motors performance standards and have been approved
for use on General
Motors vehicles.
All

Federal
safety requirements
in addition
to
these grades.
Wheel
Alignment
and
Tire
Balance
The wheels on your vehicle were aligned and balanced carefully
ar
IT.-
factory
to
give you thelongesttire
life andbestoverallperformance.
In most cases, you will not need
to
haveyourwheelsalignedagain.
However,
if
you notice unusual tire wear or your vehicle pulling one way or
the other,
the alignment may need
to
be reset.
If you notice your vehicle
vibrating when
driving on a smooth road, your wheels may need
to
be
rebalanced.
Wheel
Replacement
Replace any wheel
that
is bent, cracked or badly rusted.
If wheel nuts keep
coming
loose,
the wheel, wheel bolts, and wheel nuts should be replaced.
If
the wheel
leaks air out, replace
it
(except some aluminum wheels, which can
sometimes be repaired). See your GM dealer
if
any of
these
conditions exist.
Your dealer will know
the kind of wheel you need.
Each new wheel should have
the same
load carrying capacity, diameter,
width, offset, and be mounted
the same way as
the one
it
replaces.
If
youneed
to
replace any of your wheels, wheel
bolts, or wheel nuts,
replace
them only with
new
GM
original equipment parts. This
way, you will
be sure you have
the right wheel, wheel bolts, and wheel nuts
for your
vehicle.
