What To Check And How To Check
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 manufac-
turers.
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.
