Tire Rotation
Tire rotation can increase the useful life of the
tires by achieving uniform wear on all of the
tires. Have the tire manufacturer determine the
rotation pattern. The first tire rotation is the most
important in determining which rotation pattern
to use. Any unusual or unique wear patterns,
or indications of uneven wear that may have
developed, should be evaluated for possible
tire rotation. Misalignment, imbalance or other
mechanical problems may exist and will need to
be corrected prior to rotation.
Tread
To prevent skidding and hydroplaning, replace
tires when the tread is worn down to 4/32”
on the front, and 2/32” on the rear. Questions
regarding tread wear should be directed to the
tire manufacturer.
Built in tread wear indicators, or wear
indicators which look like narrow strips of
smooth rubber across the tread, will appear
on the tire when the tread is worn down to
2/32”. The tire should be replaced when wear
indicators are noticed.
Visually check the tires for signs of uneven
wear. Signs of irregular tread wear are usually
exhibited by low or unusually smooth areas on
the tire surface. Consult the tire manufacturer as
soon as possible.
WARNING
In many instances tire life is not
determined by mileage, but by age. Tires
are subject to weathering. Weathering
cracks run in circumference with the
tire. Though the sidewall of the tire may
look structurally sound, weathering can
occur inside the well of the tread. Have
the tire manufacturer inspect the tires
for age weathering.
Storage of Tires - Long Term
A cool, dry garage with a sealed cement floor
is the preferred method of storage. Tires stored
outside may prematurely age.
Prior to Storage:
Thoroughly clean the tires.
Unload the motorhome to reduce weight
on the tires.
Ensure the surface is reasonably level,
firm, clean and has good drainage.
Inflate the tires to the maximum inflation
pressure as indicated on the Federal
Identification Tag.
During Storage:
Cover the tires to block direct sunlight.
Periodically ensure tires are at proper
pressure.
Move the motorhome every three months
to prevent cracking in bulge areas, as
well as flat spotting from prolonged
sidewall strain and tread deflection.
Removal from Storage:
Before removing the motorhome from long-
term storage thoroughly
inspect
each tire’s
tread area and air pressure. If the tires have lost
air during storage, inflate them to the correct
pressure.

Hub Piloted Mounting:
Flange nuts generate higher
clamping force. Always use
grade eight studs with hub
mount wheels.
Before installing the
wheels, lubricate the hub
pilot pads with a drop of
oil to prevent galling.
DO
NOT
lubricate any other
wheel or hub surface.
For a hub with intermittent
pilot pads, position a pad at
the twelve o’clock position
to center the wheel and reduce runout.
NOTE
Loosen and
tighten lug nuts
in sequence (see
illustration).
Sequence tighten
to 50 ft. lbs. first,
then sequence
tighten to 500
ft lbs. Over-
tightening can
cause distortion.
Flange Nut:
Front & Side
View.

For used nuts add
two drops of oil
between flange and
hex.
