Wheel Replacement; Tyre Chains - Cadillac CTS Owner's Manual

294 VEHICLE CARE
slight pull to the left or right,
depending on the crown of the road
and/or other road surface variations
such as troughs or ruts, is normal.
If the vehicle is vibrating when driving
on a smooth road, the tyres and
wheels may need to be rebalanced.
See your dealer for proper diagnosis.

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. Some aluminium wheels
can be repaired. See your dealer if any
of these conditions exist.
Your dealer will know the kind of
wheel that is needed.
Each new wheel should have the same
load-carrying capacity, diameter,
width, offset, and be mounted the
same way as the one it replaces.
Replace wheels, wheel bolts, wheel
nuts, or Tyre Pressure Monitor System
(TPMS) sensors with new GM original
equipment parts.
Warning
Using the wrong replacement
wheels, wheel bolts, or wheel nuts
can be dangerous. It could affect
the braking and handling of the
vehicle. Tyres can lose air, and
cause loss of control, causing a
crash. Always use the correct wheel,
wheel bolts, and wheel nuts for
replacement.
Caution
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer or odometer
calibration, headlamp aim, bumper
height, vehicle ground clearance,
and tyre or tyre chain clearance to
the body and chassis.
Used Replacement Wheels
Warning
Replacing a wheel with a used one
is dangerous. How it has been used
or how far it has been driven may
be unknown. It could fail suddenly
and cause a crash. When replacing
wheels, use a new GM original
equipment wheel.

Tyre Chains

Use tyre chains or other traction
devices only when necessary.
Before using tyre chains, check with
the tyre manufacturer to make sure
tyre chains are compatible with the
tyres on the vehicle. Follow the
manufacturer's instructions.
Tyre chains are only permitted on
P245/40R18 93V size tyres. Install
them on the rear tyres only, as tightly
as possible with the ends securely
fastened.
