Traction -- A, B, C The traction grades, from highestto lowest, are A, B, and C, and they represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfacesof asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on braking (straightahead) traction tests and does not include cornering (turning) traction. Warning: The temperature grade forthis tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure. Wheel Alignment and Tire Balance The wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. Scheduled wheel alignment and wheel balancing are not needed. 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. Temperature -- A, B, C The temperature grades are A (the highest), B, and C, representing the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire C failure. The grade corresponds toa level of performance which all passenger cartires 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. Wheel Replacement Replace any wheel that is bent, cracked, or badly rusted or corroded.If wheel nuts keep comingloose, the wheel, wheel bolts and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your Oldsmobile retailer if any of these conditions exist. Your retailer will know the kind of wheel you need. 6-44

Traction
--
A,
B,
C
The traction
grades,
from
highestto lowest, are
A,
B,
and
C,
and
they
represent
the
tire’s
ability
to stop on
wet
pavement
as
measured
under
controlled
conditions
on
specified
government
test
surfaces of asphalt
and
concrete.
A
tire
marked
C
may have
poor
traction
performance.
Warning: The traction grade assigned to this tire is based
on
braking (straightahead) traction tests and does not
include cornering (turning) traction.
Temperature
--
A,
B,
C
The temperature grades
are
A
(the highest),
B,
and
C,
representing the tire’s resistance to the generation of
heat and its ability
to
dissipate heat when tested under
controlled conditions on
a
specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden tire
failure.
The
grade
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: The temperature grade
for this tire
is
established for
a
tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Wheel
Alignment
and
Tire
Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are not
needed. 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
or
corroded.
If
wheel
nuts
keep
coming loose, the wheel,
wheel bolts and wheel nuts should be replaced.
If
the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your
Oldsmobile retailer
if
any
of
these conditions exist.
Your retailer will know the kind
of
wheel
you need.
