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
Tire-Loading Information label. SeeLoading the Vehicle
on page 5‑22. Make sure not to go over the GVW limit
for the vehicle, or the GAWR, including the weight of the
trailer tongue.
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.
.The rear bumper on the vehicle is not intended for
hitches. Do not attach rental hitches or other
bumper-type hitches to it. Use only a
frame-mounted hitch that does not attach to the
bumper.
.Will there be any holes in the body of the vehicle
after installing a trailer hitch? If there are, then be
sure to seal the holes later when the hitch is
removed. If the holes are not sealed, deadly
carbon monoxide (CO) from exhaust can get into
the vehicle. See Engine Exhaust
on page 3‑34.
Dirt and water can also enter the vehicle.
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. Always
leave just enough slack so the rig can turn. Never allow
safety chains to drag on the ground.
Trailer Brakes
A loaded trailer that weighs more than 1,500 lbs
(680 kg) needs to have its own brake system that is
adequate for the weight of the trailer. Be sure to read
and follow the instructions for the trailer brakes so they
are installed, adjusted and maintained properly.
Driving with a Trailer
Towing a trailer requires a certain amount of
experience. Get to know the rig before setting out for
the open road. Get acquainted with the feel of handling
and braking with the added weight of the trailer. And
always keep in mind that the vehicle you are driving is
now longer and not as responsive as the vehicle is by
itself.

Inflation - Tire Pressure
Tires need the correct amount of air pressure to
operate effectively.
Notice:Do not let anyone tell you that under‐
inflation or over‐inflation is all right. It is not.
If your tires do not have enough air (under‐
inflation), you can get the following:
.Tire overloading and over-heating which
could lead to a blowout.
.Premature or irregular wear.
.Poor handling.
.Reduced fuel economy. If your tires have too much air (over‐inflation),
you can get the following:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from road hazards.
A vehicle specific Tire and Loading Information
label is attached to your vehicle. This label shows
your vehicle's original equipment tires and the
correct inflation pressures for your tires when they
are cold. The recommended cold tire inflation
pressure, shown on the label, is the minimum
amount of air pressure needed to support your
vehicle's maximum load carrying capacity.
For additional information regarding how much
weight your vehicle can carry, and an example of
the Tire and Loading Information label, see
Loading the Vehicle
on page 5‑22. How you load
your vehicle affects vehicle handling and ride
comfort. Never load your vehicle with more weight
than it was designed to carry.

When It Is Time for New Tires
Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions
influence when you need new tires.
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining. SeeTire
Inspection and Rotation
on page 6‑60for
additional information.
The rubber in tires ages over time, even if they are not
being used. This is also true for the spare tire, if your
vehicle has one. Multiple conditions affect how fast this
aging takes place, including temperatures, loading
conditions, and inflation pressure maintenance. Tires
will typically need to be replaced due to wear before
they may need to be replaced due to age. Consult the
tire manufacturer for more information on when tires
should be replaced.
Vehicle Storage
Tires age when stored normally mounted on a parked
vehicle. Park a vehicle that will be stored for at least a
month in a cool, dry, clean area away from direct
sunlight to slow aging. This area should be free of
grease, gasoline or other substances that can
deteriorate rubber.
Parking for an extended period can cause flat spots on
the tires that may result in vibrations while driving.
When storing a vehicle for at least a month, remove the
tires or raise the vehicle to reduce the weight from the
tires.
Buying New Tires
GM has developed and matched specific tires for
your vehicle. The original equipment tires installed
on your vehicle, when it was new, were designed
to meet General Motors Tire Performance Criteria
Specification (TPC Spec) system rating. If you
need replacement tires, GM strongly recommends
that you get tires with the same TPC Spec rating.
This way, your vehicle will continue to have tires
that are designed to give the same performance
and vehicle safety, during normal use, as the
original tires.
