Wheels and Tires
Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer.
See the warranty manual
for information regarding
the tire warranty and
where to get service. For
additional information refer
to the tire manufacturer.

Vehicle Care 335
{Warning
.Poorly maintained and
improperly used tires
are dangerous.
.Overloading the tires
can cause overheating
as a result of too much
flexing. There could be
a blowout and a serious
crash. See Vehicle Load
Limits0202.
.Underinflated tires
pose the same danger
as overloaded tires. The
resulting crash could
cause serious injury.
Check all tires
frequently to maintain
the recommended
pressure. Tire pressure
should be checked
when the tires are cold.
(Continued)
Warning (Continued)
.Overinflated tires are
more likely to be cut,
punctured, or broken by
a sudden impact —such
as when hitting a
pothole. Keep tires at
the recommended
pressure.
.Worn or old tires can
cause a crash. If the
tread is badly worn,
replace them.
.Replace any tires that
have been damaged by
impacts with potholes,
curbs, etc.
.Improperly repaired
tires can cause a crash.
Only your dealer or an
authorized tire service
center should repair,
replace, dismount, and
mount the tires.
(Continued)
Warning (Continued)
.Do not spin the tires in
excess of 56 km/h
(35 mph) on slippery
surfaces such as snow,
mud, ice, etc. Excessive
spinning may cause the
tires to explode.
All-Season Tires
This vehicle may come with
all-season tires. These tires
are designed to provide good
overall performance on most
road surfaces and weather
conditions. Original equipment
tires designed to GM's specific
tire performance criteria have
a TPC specification code
molded onto the sidewall.
Original equipment all-season
tires can be identified by the
last two characters of this
TPC code, which will be “MS.”
Consider installing winter tires
on the vehicle if frequent
driving on snow or ice-covered

342 Vehicle Care
and the original equipment
tire size and recommended
inflation pressure. See“Tire
and Loading Information
Label” under Vehicle Load
Limits 0202.
Tire Pressure
Tires need the correct
amount of air pressure to
operate effectively.
{Warning
Neither tire underinflation
nor overinflation is good.
Underinflated tires,
or tires that do not have
enough air, can result in:
.Tire overloading and
overheating, which
could lead to a blowout
.Premature or
irregular wear
.Poor handling
(Continued)
Warning (Continued)
.Reduced fuel economy
for internal combustion
engine vehicles
.Reduced range for
electric vehicles
Overinflated tires, or tires
that have too much air,
can result in:
.Unusual wear
.Poor handling
.Rough ride
.Needless damage from
road hazards
The Tire and Loading
Information label on the
vehicle indicates the
original equipment tires
and the correct cold tire
inflation pressures. The
recommended pressure is
the minimum air pressure
needed to support the vehicle's maximum load
carrying capacity. See
Vehicle Load Limits
0202.
How the vehicle is loaded
affects vehicle handling
and ride comfort. Never
load the vehicle with more
weight than it was
designed to carry.
When to Check
Check the pressure of the
tires once a month or more.
How to Check
Use a good quality
pocket-type gauge to
check tire pressure. Proper
tire inflation cannot be
determined by looking at
the tire. Check the tire
inflation pressure when the
tires are cold, meaning the
vehicle has not been driven
for at least three hours or
no more than 1.6 km (1 mi).
