Ball Coupler Hitches
Coupler assembly includes a latch lever and latch
lever safety pin or hitch pin. Be sure the latch lever is
locked and the pin properly secured before moving
your trailer. The pin can be engaged fully only if ball
is properly seated in the coupler.
Tires
Before mounting tires onto wheels make certain that
the rim size and contour is approved for the tire as
shown in the Tire and Rim Association Yearbook or
the tire manufacturer's catalog. Also make sure the
tire will carry the rated load. If the load is not equal
on all tires due to trailer weight distribution, use the
tire rated for the heaviest wheel position.
NOTE: The capacity rating molded into the sidewall of
the tire is not always the proper rating for the tire if used
in a trailer application. Use the following guideline:
1. LT and ST tires: use the capacity rating molded
into the tire.
2. Passenger Car Tires: Use the capacity rating
molded into the tire sidewall divided by 1.10.
Use tire mounting procedures as outlined by the
Rubber Manufacturer's Association or the tire manu-
facturers.

NOTE: Tire wear should be checked frequently
because once a wear pattern becomes firmly
established in a tire it is difficult to stop, even
if the underlying cause is corrected.
