IMPORTANT INFORMATION
This trailer’s Hitch Coupler MUST be
properly secured to the hitch ball of the towing
vehicle. After assembly and attachment, pull
up and down on the Hitch Coupler to make
sure the hitch ball is tting snugly in the Hitch
Coupler. There must be no play between the
hitch ball and the Hitch Coupler. If there is
play, tighten the Adjustment Nut until no play
is present. If the Adjustment Nut is too tight,
the Handle will not lock. Carefully read and
follow the complete instructions in this
manual BEFORE setup or use.
If the coupler is not secured
properly, the ball could come loose
while the trailer is in motion, possibly
causing property damage, SERIOUS
PERSONAL INJURY, or DEATH.

TIRE INFORMATION
Tire Terminology Glossary
Accessory weight means• - the combined weight of
automatic transmission, power steering, power brakes,
power windows, power seats, radio, and heater, to the extent
that these items are available as factory-installed equipment.
Carcass means• - the tire structure except for the tread
which provides the major portion of the tire’s capability
to deect in response to the vertical loads and tractive
forces that the tire transmits from the roadway to the non-
pneumatic rim, the wheel center member, or the vehicle
and which attaches to the vehicle or attaches, either
integrally or separably, to the wheel center member or
non-pneumatic rim.
Carcass separation means• - the pulling away of the carcass
from the non-pneumatic rim or wheel center member.
Chunking means• - the breaking away of pieces of the
carcass or tread.
Cracking means• - any parting within the carcass, tread, or
any components that connect the tire to the wheel center
member.
Curb weight means• - the weight of a motor vehicle with
standard equipment including the maximum capacity of
fuel, oil, and coolant, and, if so equipped, air conditioning
and additional weight optional engine.
Load rating means• - the maximum load a tire is rated to carry.
Maximum loaded vehicle weight means• - the sum of:
Curb weight;a.
Accessory weight;b.
Vehicle capacity weight; andc.
Production options weight.d.
Maximum tire width means• - the greater of either the linear
distance between the exterior edges of the carcass or the
linear distance between the exterior edges of the tread, both
being measured parallel to the rolling axis of the tire.
Normal occupant weight means• - 68 kilograms times the
number of occupants.
Occupant distribution means• - distribution of occupants
in a vehicle.
Production options weight means• - the combined weight
of those installed regular production options weighing over
2.3 kilograms in excess of those standard items which
they replace, not previously considered in curb weight
or accessory weight, including heavy duty brakes, ride
levelers, roof rack, heavy duty battery, and special trim.
Tread means• - that portion of the tire that comes in
contact with the road.
Tread separation means• - pulling away of the tread from
the carcass.
Vehicle capacity weight means• - the rated cargo and
luggage load plus 68 kilograms times the vehicle’s
designated seating capacity.
Vehicle maximum load on the tire means• - that load on
an individual tire that is determined by distributing to each
axle its share of the maximum loaded vehicle weight and
dividing by two.
Vehicle normal load on the tire means• - that load on an
individual tire that is determined by distributing to each
axle its share of the curb weight, accessory weight, and
normal occupant weight and dividing by 2.

Section width• - This number gives the width of the tire in
inches. The larger the number, the wider the tire. (The
markings on the example tire diagram show 4.80. The
markings on your tire may differ.)
Inner diameter• - This number gives the inner diameter of
the tire in inches. This is also the rim diameter in inches.
(The markings on the example tire diagram show 12.
The markings on your tire may differ.)
U.S. DOT tire identication number• - This begins with
the letters “DOT” and indicates that the tire meets all
federal standards. The next two numbers or letters
are the plant code where it was manufactured, and the
last four numbers represent the week and year that the
tire was built. For example, the numbers 2107 mean
the 21st week of 2007. Any other numbers used are
marketing codes used at the manufacturer’s discretion.
This information is used to contact consumers if a tire
defect requires a recall.
Maximum Load Rating• - This number indicates the
maximum load in kilograms and pounds that can be
carried by the tire.

Load Index Rating Codes
• Load index- This is a measurement of how much weight
each tire can support. See chart above. (The markings
on the example tire diagram show 71. The markings
on your tire may differ.) Note: You may not nd this
information on all tires because it is not required by law.

Tire Speed Rating Codes
• Speed Rating- The speed rating denotes the speed at
which a tire is designed to be driven for extended periods
of time. This does not indicate that the vehicle or rims
can safely reach or maintain that speed. These ratings
are listed to the right. (The markings on the example tire
diagram show M. The markings on your tire may differ.)
Note: You may not nd this information on all tires
because it is not required by law.
Tire Ply Composition and Materials Used• - The
number of plies indicates the number of layers of rubber-
coated fabric in the tire. In general, the greater the
number of plies, the more weight a tire can support. Tire
manufacturers also must indicate the materials in the tire,
which include steel, nylon, polyester, and others.
Maximum Permissible Ination Pressure• - This number
is the greatest amount of air pressure that should ever be
put in the tire under normal driving conditions.
