Wheel Replacement
If the trailer has been struck, or impacted, on or near the wheels,
or if the trailer has struck a curb, inspect for damage (i.e. being
out of round); and replace any damaged wheel. Inspect the
wheels for damage every year, even if no obvious impact has
occurred.
Replacement wheels must have the same diameter, width, and
profile as the original. Replacement tires must be the same size,
ply rating, and load range as the tire being replaced. Refer to the
Vehicle Identification plate on the chassis for wheel and tire spec-
ifications.
Wheel Installation
It is extremely important to apply and maintain proper wheel
mounting torque.
WHEEL NUTS MUST BE INSTALLED AND MAINTAINED AT THE PROPER TORQUE TO
PREVENT LOOSE WHEELS, BROKEN STUDS, AND POSSIBLE DANGEROUS SEPARATION
OF WHEEL FROM THE AXLE. BE SURE TO USE ONLY THE NUTS MATCHED TO THE CONE
ANGLE OF THE WHEEL.
Tighten the lug nuts to the proper torque for the axle size on your
trailer, to prevent wheels from coming loose. Use a torque
wrench to tighten the fasteners. If you do not have a torque
wrench, tighten the fasteners with a lug wrench, then immedi-
ately have a service garage or dealer tighten the lug nuts to the
proper torque. Over-tightening will result in breaking the studs or
permanently deforming the mounting stud holes in the wheels.
The proper procedure for attaching wheels is as follows:
1. Start all nuts by hand to prevent cross threading. DO NOT
use a lubricant on threads or nuts.
2. Tighten nuts in the following sequence:
