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.
CAUTION
ALWAYS wear safety glasses when
removing or installing force fi tted 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.
Tire Wear/Infl ation
Tire infl ation 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 infl ation
pressure weekly during use to insure the maximum tire life
and tread wear.
Table 16 (Tire Wear Troubleshooting) will help pinpoint the
causes and solutions of tire wear problems.

TRAILER MAINTENANCE
Suspension
The leaf suspension springs and associated components
(Figure 63) 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 17.
