Sooner or later, an off-road trail will probably go across the incline of a hill.
If this happens, you have to decide whether to try to drive across the incline.
Here are some things to consider:

A hill that can be driven straight up or down may be too steep to drive
across. When you
go straight up or down a hill, the length of the wheel
base (the distance from the front wheels to the rear wheels)\
reduces the
likelihood the vehicle will tumble end over end. But when you \
drive
across an incline, the much more nmow track width (the distance
between the left and right wheels) may not prevent the vehicl\
e from
tilting and rolling over.
Also, drivirig across an indline puts more
weight on the downhill wheels. This could cause a downhil slide or a
rollover.
Surface conditions can be
a problem when you drive across a hill.
Loose gravel, muddy spots, or even wet grass can cause your t\
ires to
slip sideways, downhill. If the vehicle slips sideways, it can hit
something that will trip it (a rock,
a rut, etc.) and roll over.
Hidden obstacles can make the steepness of the incline even worse.
I€
you drive across a rock with the uphill wheels, or if the do\
wnhill
wheels drop into a rut
or depression, your vehicle can tilt even more.
For reasons like these,
you need to decide carefully whether to try to drive
across an incline. Just because the trail goes across the incl\
ine doesn’t mean
you have to drive it. The last vehicle to
try it might have rolled over.

Downloaded from www.Manualslib.com manuals search engine 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 tes\
t wheel.
Sustained high temperature can cause the material of the tire to degenerate
and reduce tire life, and excessive temperature can lead to su\
dden 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, underinfla\
tion, 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.
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, 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.
