WARNING
WHEN REPLACING TIRES CONSULT THE WHEEL AND TIRE
MANUFACTURERS’ SPECIFICATIONS FOR COMPATIBILITY. IMPROPERLY
MATCHED WHEELS AND TIRES MAY FAIL AND CAUSE PROPERTY
DAMAGE, SERIOUS PERSONAL INJURY, OR LOSS OF LIFE.
Wheel Bearing Lubrication
There is no need to lift the vehicle before greasing axles
equipped with today’s modern “easy-lube” technologies:
Remove the rubber plug from grease cap.
Insert grease gun on the grease zerk.
Pump until new grease begins to appear.
Replace rubber plug.
Hubs and components should also be disassembled
yearly and inspected for worn or otherwise damaged
parts.
WARNING
KEEP TIRES PROPERLY INFLATED. A TIRE THAT IS RUN LONG
DISTANCES OR AT HIGH SPEEDS WHILE SERIOUSLY UNDERINFLATED
WILL OVERHEAT TO THE POINT WHERE THE TIRE MAY LOSE AIR
SUDDENLY AND/OR CATCH FIRE, POSSIBLY RESULTING IN DAMAGE
TO THE VEHICLE AND ITS CONTENTS AND OR PERSONAL INJURY.
Tires and Wheels
The tires should be checked before starting on every trip.
Check them regularly and keep inflated to recommended
pressures. The recommended tire pressure is on the
side of the tire. Rotate tires at least once every 5,000
miles or as recommended by the tire manufacturer.
Most models have a spare tire available in case of an
emergency.
All vehicles are equipped with tubeless tires. They are
designed for today’s turnpike speeds and are rated to
carry the weight of the trailer plus your family’s personal
needs for an extended vacation. If you should require an
adjustment on a faulty or defective tire, secure the name
of your nearest tire dealer or distributor and request an
adjustment according to the conditions and terms of the
warranty.
Tire Changing
1. Use emergency flares when near a road or highway.
2. Block wheels on the opposite side from the tire you
wish to change to prevent accidental movement.
3. Position a hydraulic jack on the frame close to the
spring hanger.
4. Raise the trailer until the tire clears the ground.
WARNING
CHECK TIRE PRESSURES BEFORE TRAVELING. ALWAYS CHECK TIRE
PRESSURE WHEN TIRES ARE COLD. DO NOT EXCEED THE MAXIMUM
RECOMMENDED PRESSURE.
The Importance of Proper Tire Inflation
Your trailer tires and wheels, and tongue or fifth-
wheel hitch, support the entire weight of the trailer
and its contents. The tires are also the only contact
the trailer has with the road surface. Determining and
maintaining proper inflation is the most important factor
in maximizing the life of your tires. Driving on a tire that
does not have the correct inflation pressure for the trailer
load is dangerous and may cause premature wear, tire
damage, tread delaminating and/or loss of control of the
trailer and/or tow vehicle.
