What to Check And How To Check

Wheel Torque Requirements

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.
