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 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 right wheel, wheel bolts, and wheel nuts for your
Cadillac model.

CAUTION:
Using the wrong replacement wheels, wheel bolts, or wheel nuts
on your vehicle can be dangerous. It could affect the braking
and handling of your vehicle, make your tires lose air and make
you lose control. You could have a collision in which you or
others could be injured. Always use the correct wheel, wheel

bolts, and wheel nuts for replacement.
