Service manual

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.
Meel 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 Cadillac 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 you need 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 to have the riqht wheel, wheel bolts, and wheel nuts for your
Cadillac model.
