Different Size Tyres And Wheels; Wheel Alignment And Tyre Balance; Wheel Replacement - Cadillac CTS 2013 Owner's Manual

10-72 Vehicle Care
Vehicles that have a tyre
pressure monitoring system
could give an inaccurate
low-pressure warning if non-TPC
Spec rated tyres are installed.
See Tyre Pressure Monitor
Operation on page 10 64.
The Tyre and Loading
Information label indicates the
original equipment tyres on the
vehicle. See Vehicle Load Limits
on page 9 9 for the label
location and more information
about the Tyre and Loading
Information label.
Different Size Tyres and
Wheels
If wheels or tyres are installed that
are a different size than the original
equipment wheels and tyres, vehicle
performance, including its braking,
ride and handling characteristics,
stability, and resistance to rollover
may be affected. If the vehicle has
electronic systems such as anti-lock
brakes, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can also be affected.
WARNING
If different sized wheels are used,
there may not be an acceptable
level of performance and safety if
tyres not recommended for those
wheels are selected. This
increases the chance of a crash
and serious injury. Only use GM
specific wheel and tyre systems
developed for the vehicle, and
have them properly installed by a
GM certified technician.
See Buying New Tyres on
page 10 70 and Accessories and
Modifications on page 10 3.
Wheel Alignment and
Tyre Balance
The tyres and wheels were aligned
and balanced at the factory to
provide the longest tyre life and best
overall performance. Adjustments to
wheel alignment and tyre balancing
will not be necessary on a regular
basis. However, check the
alignment if there is unusual tyre
wear or the vehicle is pulling to one
side or the other. If the vehicle is
vibrating when driving on a smooth
road, the tyres 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 tyres 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.
