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