WARNING
If you use bias-ply tires on the
vehicle, the wheel rim flanges
could develop cracks after
many miles of driving. A tire
and/or wheel could fail
suddenly, causing a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If you must replace your
vehicle's tires with those that do
not have a TPC Spec number,
make sure they are the same
size, load range, speed rating,
and construction type (radial and
bias‐belted tires) as your
vehicle's original tires.
Vehicles that have a tire
pressure monitoring system
could give an inaccurate
low‐pressure warning if
non‐TPC Spec rated tires are
installed on your vehicle.
Non‐TPC Spec rated tires may
give a low‐pressure warning that
is higher or lower than the
proper warning level you would
get with TPC Spec rated tires.
See Tire Pressure Monitor
System
on page 9‑47
.
Your vehicle's original
equipment tires are listed on the
Tire and Loading Information
Label. See Vehicle Load Limits
on page 8‑24
, for more
information about the Tire and
Loading Information Label and
its location on your vehicle.
Different Size Tires and
Wheels
If you add wheels or tires that are a
different size than your original
equipment wheels and tires, this
could affect the way your vehicle
performs, including its braking, ride
and handling characteristics,
stability, and resistance to rollover.
Additionally, if your vehicle has
electronic systems such as anti‐lock
brakes, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can be affected.
{
WARNING
If you add different sized wheels,
your vehicle may not provide an
acceptable level of performance
and safety if tires not
recommended for those wheels
are selected. You may increase
the chance that you will crash and
suffer serious injury. Only use GM
specific wheel and tire systems
developed for your vehicle, and
have them properly installed by a
GM certified technician.
