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 15 (Tire Wear Troubleshooting) will help pinpoint the
causes and solutions of tire wear problems.
Suspension
The
leaf suspension
springs and associated components
(Figure 58) should be visually inspected every 6,000 miles
for signs of excessive wear, elongation of bolt holes, and
loosening of fasteners. Replace all damaged parts
(suspension) immediately. Torqued suspension components
as detailed in Table 16.

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.
CAUTION - REPAIRING TRAILER WHEELS
ALWAYS
wear safety glasses when
removing or installing force fitted parts.
Failure to comply may result in serious
injury.
