Section 4: Vehicle Operation
Wheel lugs
If you suspect or notice the wheel stud bolts are cracked or broken, they must be replaced,
along with adjacent bolts that have probably also been weakened due to the additional stress
placed on them.
Aluminum Wheels (if so equipped)
Clean the aluminum wheels with a cleaner that is designed for use on aluminum and apply
an appropriate protection agent. Do not use abrasive cleaners. Wheels exposed to sea water
or road chemicals should be cleaned as soon as possible. Be sure to use a sponge or chamois
leather (brushes may damage the aluminum wheel surface.)
NOTE: If your motor home is equipped with aluminum wheels, only
the outer dual wheels are aluminum, the inner duals are steel wheels.
Tires
Read and understand the following before taking your first trip in your RV.
Routine maintenance on your RV is important.
To insure your tires are operating safely,
regular inspection of the tires and checking tire pressures is absolutely mandatory.
Alignment, balance and bearing wear will affect tire wear. Make sure to look for cracking,
bulging, uneven tread wear, etc.
