Recreational Vehicle Towing (Except Four-wheel Drive With
Manual Shift Transfer Case) Loading Your Vehicle
Vehicles with
two-wheel drive or the optional electronic
shift transfer case require special modifications before
they can be towed
in this manner. Please contact your
dealer for the towing information that
is appropriate for
your particular vehicle.
Vehicles
with all-wheel drive (AWD) can not be towed
in this manner.
The Certification/Tire label is found on the driver’s door
edge, above the door latch. The label shows the size
of
your original tires and the inflation pressures needed to
obtain the gross weight capacity of your vehicle. This is
called the GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight
of the vehicle, all occupants,
fuel, cargo and trailer tongue weight,
if pulling a trailer.
4-42

A B
If you're using a weight-carrying hitch, the trailer
tongue
(A) should weigh 10 percent of the total loaded
trailer weight
(B). If you're using a weight-distributill~
hitch, the trailer tongue
(A) should weigh I2 percent of
the total loaded trailer weight (B).
After you've loaded your trailer, weigh the trailer and
then the tongue, separately, to see
if the weights are
proper.
If they aren't, you may be able to get them right
simply by moving some. items around in the trailer.
Total Weight on Your Vehicle's Tires
Be sure your vehicle's tires are inflated to the upper
limit for cold tires. You'll find these numbers on the
Cel-tification/Tire
label on the driver's door edge, above
the door latch,
or see "Tire Loading" in the Index. Then
be
SL~ you don't go over the GVW limit for your
vehicle, including the weight
of the trailer tongue.
Hitches
It's important to have the correct hitch equipment.
Crosswinds. large trucks going
by and rough roads are a
few reasons why you'll need the right hitch. Here are
some rules to follow:
0 If' YOLI'II be pulling a trailer that, when loaded, will
weigh more than
2,000 lbs. (900 kg), be sure to LW a
properly mounted, weight-distributing hitch and
sway control of the proper size. This equipment is
very important for proper vehicle loading and good
handling when you're driving.

Return the jack, wheel wrench and wheel blocks to the
proper location in your vehicle’s rear area. Secure the
items and replace the jack cover.

Make sure the tire and carrier are secure.
Driving with the tire or carrier unlatched could
injure pedestrians or damage the vehicle.
Compact Spare Tire (If Equipped)
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after a time. Check
the inflation pressure regularly. It should be
60 psi
(420 Wa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make sure
your spare tire is correctly inflated. The compact
spare is made to perform well at speeds up to
65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full-size tire
repaired or replaced where
you want. Of course, it’s best
to replace your spare with a full-size tire as
soon as you
can. Your spare will last longer and be in good shape in
case you need it again.

When It's Time for New Tires
One way to tell when it's
time for new tires is to
check the treadwear
indicators, which will
appear
when YOLII- tires have
only 1/16 inch ( I .6 mm) or
less
of tread remaining.
You need a new tire if any of the following statements
are true:
0 You can see the indicators at three or more places
around the tire.
You can see cord or hbric showing through the
tire's rubber.
The tread or sidewall is cracked. cut or snagged deep
enough
to show cord or fabric.
The tire has a bump. bulge or split.
The tire has a puncture, cut or other damage that
can't be repaired well because of the size or location
of the darnage.
Buying New Tires
To find out what kind ;m.l size of tires you need, look at
the CertificatiodTire label.
The tires installed on your vehicle when
it was new had
a Tire Performance Criteria Specification (TPC Spec)
number
on each tire's sidewall. When you get new tires,
your vehicle
will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction. ride and other things during normal service
on
your vehicle. If your tires have an all-season tread
design, the
TPC number will be followed by an "MS"
(for mud and snow).
If you ever replace your tires with those not hktving a
TPC Spec number. make sure [hey are the same size.
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
c get ones with that same TPC Spec number. That way
6-44

Mixing tires could cause you to lose control while
driving.
If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have
a crash.
Using tires
of different sizes may also cause
damage to
your vehicle. Be sure to use the same
size and type tires
on all wheels.
It’s all right to drive with your compact spare
(if you have one). It was developed for
use on
your vehicle.
Uniform Tire Quality Grading
The following information relates to the system
developed
by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear. traction and temperature performance. (This
applies only to vehicles
sold in the United States.) The
grades are molded on the sidewalls of most passenger
car tires. The Uniform Tire Quality Grading system does not
apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires with
nominal
rim diameters of 10 to 12 inches (25 to 30 cm),
or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary
with respect to these
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
c Urades, they rnust also conform to Federal safety
Treadwear
The treadwear grade is a comparative rating based
on
the wear rate of the tire when tested under controlled
conditions on
a specified government test course. For
example.
a tire graded 150 would wear one and a half
( 1 1/2) times as well on the government course as a tire
upon the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and clilnate.

Tire Chains
NOTICE:
If your vehicle has P235/75R15, P235/70K15 or
31xlOSOR15LT/C size tires, don’t use tire chains.
They can. damage your vehicle because there’s
not enough clearance.
Use another type of traction device only
if its
manufacturer recommends it for use on your vehicle and tire size combination and road
conditions. Follow that manufacturer’s
instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if it’s contacting your vehicle, and don’t
spin your wheels.
NOTICE: (Continued)
NOTICE: (Continued)
If you do hd a traction device that will fit, install
them on the rear tires.
If you have other size tires, use tire chains only
where legal and only when you must. Use only
SAE Class “S” type chains that are the proper
size for your tires. Install them on the drive axle
tires (,four-wheel-drive vehicles can use chains on both axles) and tighten them as tightly
as possible
with the ends securely fastened. Drive slowly and
follow the chain manufacturer’s instructions.
If
you can hear the chains contacting your vehicle,
stop and retighten them.
If the contact continues,
slow down until it stops. Driving
too fast or
spinning the wheels with
chains on will damage
your vehicle.
