Black plate (85,1)
Cadillac CTS/CTS-V Owner Manual - 2011
Vehicle Care
10-85
The grade C corresponds to a
level of performance which all
passenger car tires must meet
under the Federal Motor 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 tires and wheels on your
vehicle were aligned and balanced
carefully at the factory to give you
the longest tire life and best overall
performance. Adjustments to wheel
alignment and tire balancing will not
be necessary on a regular basis.
However, if you notice unusual
tire wear or your vehicle pulling to
one side or the other, the alignment
might need to be checked. If you
notice your vehicle vibrating when
driving on a smooth road, the tires
and wheels might need to be
rebalanced. See your dealer for
proper diagnosis.
CTS-V models should only use
adhesive wheel weights to balance
the tires and wheels.
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 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.
