WARNING:
Do not overinflate or
underinflate tires. Sudden
tire failure can result.
The yellow Federal Certication
Label, attached to the wall
adjacent to the driver’s seat, lists
the Gross Axle Weight Ratings
(GAWR). These ratings are the
maximum allowable weights per
axle position.
When the actual loaded weight
of the motorhome and the weight
on each axle is unknown, follow
the recommended tire ination
pressure(s) listed on the Federal
Certication Label. Never exceed
the Gross Vehicle Weight Rating
(GVWR) or the Gross Axle
Weight Rating (GAWR). Contact
the tire manufacturer for further
information concerning ination
pressure and other tire concerns.
NOTE:
The motorhome is
equipped with Michelin
315/80R/22.5 radial tires at
the time of printing. The
motorhome manufacturer
will not be responsible for
substitution of an incorrect
tire size or load range.
Verify actual tire brand,
size and load range before
obtaining replacement
tires.
Inspecting & Pressure
Ination pressure is rated at a
cold psi. Cold psi is dened as
early in the morning before the
day’s ambient temperature, sun’s
radiant heat or heat generated
while driving
has caused
ination pressure
to temporarily
increase. Check
tire ination
pressure every
morning before
driving. Use
a high-quality
truck tire
gauge with an
angle airhead to
ensure access to
the dual wheel
positions of the
drive axle.
Ensure the
valve cap is
replaced on the
stem after the
ination pressure
is checked. Use
valve stem caps
with a positive
seal to prevent air
from escaping
through the
valve stem.
If there are extension hoses on
the valve stem, make sure they are
high-quality reinforced stainless
steel braid. Attach hoses securely
to the outer wheel to prevent
movement. The valve stem cap
guarantees the valve core will
remain free of dirt and foreign
material. Material lodged between
the valve core and internal stem
can cause slow leaks resulting in
tire failure.
Optimum tire performance
is achieved at proper ination
pressure for the load carried. Do
not mix tires of different tread
patterns, size or construction on
the same axle. The difference
could result in damage to the
drivetrain or handling issues.
The motorhome may be
equipped with an on-board “tire
pressure monitoring” system.
Individual tire pressures are
displayed on the monitor when
the feature is selected. The tire
pressure monitoring system is to
be used for “Reference Only”. To
accurately determine individual
tire pressure, a reliable and
calibrated tire pressure gauge in
good working condition should
be used. The Federal Certication
Label for proper tire ination
pressure. Follow the guidelines in
this owner’s manual for checking
air tire pressure. Consult your
monitor system’s owner’s manual
for additional information.
