Traction - A, B, C
The traction grades, from highest to lowest are: A, B, and C. 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
(straight-ahead) traction tests and does not include cornering (turning)
traction.
Temperature - A, By 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.
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 with respect to these grades, all such tires meet
General Motors performance standards and have been approved for use on
General Motors vehicles. All passenger type
(P Metric) tires must conform
to Federal safety requirements in addition to these grades.
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.
In most cases, you will not need to have your wheels aligned again.
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.

2 I. THERMOSTATICALLY CONTROLLED ENGINE COOLING FAN INSPECTIONAI/
- (If so equipped.) Inspect all hoses and
ducts for proper hook-up. Be sure the valve works properly.
22. EXHAUST PRESSURE REGULATOR VALVE INSPECTION” -
Check that the valve works properly, Correct any binding. Inspect
hoses for cracks, chafing or decay. Replace parts as needed.
23. TIRE AND WHEEL ROTATION AND INSPECTION - For proper
wear and maximum tire life, rotate tires at the first 6,000 miles
(10 000
kilometers) for Schedule
I (+) or 7,500 miles (12 500 kilometers) for
Schedule
I1 (0) and then every 15,000 miles (25 000 kilometers)
thereafter. Follow the instructions and patterns shown
in Section 6.
Check tires for uneven wear or damage. If irregular or premature wear is
apparent, check wheel alignment. Also, check or damaged wheels. See
“Tires”
in the Index for more information.
For dual wheels, whenever the vehicle, wheels, or fasteners are new,
have the wheel fastener torque
set at the first 100, 1,000 and 6,000 miles
( 160, 1600 and 10 000 km).
Block the tires opposite
those being removed to keep the vehicle from
rolling.
24.
DRIVE AXLE SERVICE? - Check readfront axle fluid level and
add
as needed. Check constant velocity joints and axle seals for
leaking.
0 Locking differential - Drain fluid at first oil change and refill.
Check fluid
level and add as needed at subsequent oil changes. In
dusty areas, or trailer towing applications drain fluid at every
15,000 miles (24 135 kilometers) and refill.
Standard differential - Check fluid level and add as needed at
every oil change. In dusty areas, or trailer towing applications,
drain fluid every
15,000 miles (24 135 kilometers) and refill.
0 More frequent lubrication may be required on heavy-duty or
off-road
use.
