MAINTENANCE (TRAILER)
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
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 . Check inflation pressure weekly during use to insure the maximum tire life and tread wear.
Table 14 (Tire Wear Troubleshooting) will help pinpoint the causes and solutions of tire wear problems.
