Total Weight on the Vehicle's
Tires
Be sure the vehicle's tires are
inflated to the upper limit for cold
tires. These numbers can be found
on the Certification/Tire label
located at the bottom of the center
pillar on the driver's side of the
vehicle, or seeVehicle Load Limits
on page 9‑20. Make sure not to go
over the GVW limit for the vehicle,
or the GAWR, including the weight
of the trailer tongue. If using a
weight distributing hitch, make sure
not to go over the rear axle limit
before applying the weight
distribution spring bars.
Towing Equipment
Hitches
It is important to have the correct
hitch equipment. Crosswinds, large
trucks going by and rough roads are
a few reasons why the right hitch is
needed.
Weight-Distributing Hitches
and Weight Carrying Hitches
A step bumper hitch can be used for
trailers up to 907 kg (2,000 lbs) total
weight, and 90 kg (200 lbs) tongue
weight.
Notice: If a step-bumper hitch is
used, the bumper could be
damaged in sharp turns. Make
sure there is ample room when
turning to avoid contact between
the trailer and the bumper.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Instructions about safety chains
may be provided by the hitch
manufacturer or by the trailer
manufacturer. For trailers up to
907 kg (2,000 lbs) safety chains may
be attached to the attaching points
on the bumper. For heavier trailers,
follow the trailer or hitch
manufacturer's recommendation for
attaching safety chains. Always
leave just enough slack so the rig
can turn. Never allow safety chains
to drag on the ground.

Tires
This new vehicle comes with
high-quality tires made by a
leading tire manufacturer. If you
ever have questions about your
tire warranty and where to
obtain service, see the vehicle
Warranty booklet for details. 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. You
could have a blowout and a
serious accident. See
Vehicle
Load Limits on page 9‑20.

Black plate (47,1)Chevrolet Colorado Owner Manual - 2011
Vehicle Care 10-47
WARNING (Continued)
.Under inflated 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.
.Over inflated tires are more
likely to be cut, punctured,
or broken by a sudden
impact—such as when you
hit 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.
(Continued)
WARNING (Continued)
.Improperly repaired tires can
cause a crash. Only the
dealer or an authorized tire
service center should repair,
replace, dismount, and mount
the tires.
.Do not spin the tires in
excess of 55 km/h (35 mph)
on slippery surfaces such as
snow, mud, ice, etc.
Excessive spinning may
cause the tires to explode.
