K10 – 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.
{ 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
Limits 0 169 .
(Continued) Warning (Continued) .
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. .
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.

dealer or trailering professional
for additional advice and
equipment recommendations.

the vehicle is prepared to be
towed.
CautionUse of a shield mounted in front
of the vehicle grille could restrict
airflow and cause damage to the
transmission. The repairs would
not be covered by the vehicle
warranty. If using a shield, only
use one that attaches to the
towing vehicle. Dinghy Towing
To dinghy tow the vehicle from the
front with all four wheels on the
ground:
1. Position the vehicle to tow and
then secure it to the towing
vehicle.
2. Turn the ignition on, and shift
the transmission to N (Neutral).
3. With the transmission in
N (Neutral), turn the ignition off.
4. To prevent the battery from
draining while the vehicle is
being towed, remove fuses
29 and 32 (Body Control Module) from the instrument
panel fuse block. See
Instrument Panel Fuse Block
0 261 . Remember to reinstall
the fuses once the destination
has been reached.
Dolly Towing (All-Wheel-Drive

All-wheel-drive vehicles must not be
towed with two wheels on the
ground. To properly tow these
vehicles, they should be placed on
a platform trailer with all four wheels
off of the ground.
