Air Pressure Checklist
When inspecting the tires, confirm
the tires are cool before increasing or
reducing air pressure. Driving a short
distance can heat up tires.
NOTE:
If the motorhome must be driven a
distance to get air, check and record
the tire pressure first and add the
recorded calculation when reaching
the pump. It is normal for tires to
heat up and the air pressure inside
to go up as driven. Do not reduce air
pressure when tires are hot.
Remove the cap from the valve on one
tire.
Firmly press a tire gauge onto the valve
and record reading.
Add air to achieve recommended air
pressure.
If the tire is overfilled, release air by
pushing on the metal stem in the center
of the valve. Recheck the pressure with
the tire gauge.
Replace the valve cap.
Repeat with each tire.
Visually
inspect
all the tires for nails or
other objects that could be embedded
or puncture the tire and cause an air
leak.
Check the sidewalls for gouges, cuts,
bulges, or other irregularities.
NOTE:
Air pressure in a tire increases (warm
weather) or decreases (cold weather)
one to two pounds for every 10° F of
temperature change.

Tire Support When Leveling
Extreme caution must be taken to ensure the
tires are fully supported when placing blocks
under the tires. The load on the tire should be
evenly distributed on the support block. In the
case of dual tires, distribute the load evenly on
blocks for both tires. If not properly supported,
the steel cables in the sidewall of the tires
may be damaged and could lead to premature
fatigue of the sidewall.
CAUTION:
Supporting the tires prevents damage
to the sidewall of the tires but does not
prevent tire roll.
Tire Vibration
Sudden tire failure is often preceded by tire
vibration. Symptoms that can cause tire failure
are a bulge in the sidewall or swelling in the
tire carcass. Striking an object or large hole in
the road surface can damage a tire. Inspect the
tires periodically thereafter as rotational forces
can continue to stress damaged areas and later
manifest in tire failure. If an unusual vibration
begins or a bulge is noticed in the sidewall,
have the tires evaluated by a qualified
professional as soon as possible.
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.
