Torque suspension components (Figure 65) as referenced
in Table 16.
tires/Wheels/lug nuts
Tires and wheels are a very important and critical
components of the trailer. When specifying or replacing
the trailer wheels it is important the wheels, tires, and axle
are properly matched.
tire Wear/inflation
Tire inflation pressure is the most important factor in tire
life. Pressure should be checked cold before operation
DO
NOT
bleed air from tires when they are
hot!
. Check inflation
pressure weekly during use to insure the maximum tire life
and tread wear.
Table 17 (Tire Wear Troubleshooting) will help pinpoint the
causes and solutions of tire wear problems.

caution
alWaYs
wear safety glasses when
removing or installing force fitted parts.
Failure to comply may result in serious
injury.
caution
DO NOT
attempt to repair or modify a
wheel.
DO NOT
install in inner tube to
correct a leak through the rim. If the rim is
cracked, the air pressure in the inner tube
may cause pieces of the rim to explode (break off) with
great force and cause serious eye or bodily injury.
lug nut torque requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the
fasteners matched to the cone angle of the wheel. Proper
procedure for attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts in sequence (see Figure 66).
DO
NOT
torque the wheel lug nuts all the way down.
Tighten each lug nut in 3 separate passes as defined
by Table 18.
3. After first road use, retorque all lug nuts in sequence.
Check all wheel lug nuts periodically.

Tire Wear Troubleshooting
Wear Pattern
Cause
Solution
Center Wear Over inflation.
Adjust pressure to particular
load per tire manufacturer.
Edge Wear
Under inflation.
Adjust pressure to particular
load per tire manufacturer.
Side Wear
Loss of camber
or overloading.
Make sure load does not
exceed axle rating.
Align wheels.
Toe Wear
Incorrect toe-in.
Align wheels.
Cupping
Out-of-balance.
Check bearing adjustment
and balance tires.
Flat Spots
Wheel lockup and
tire skidding.
Avoid sudden stops when
possible and adjust brakes.
