Air Pressure Checklist
1. 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 to increase as driven. NEVER
reduce air pressure when tires are hot.
NOTE
Air pressure in a tire goes up (in warm
weather) or down (in cold weather)
one to two pounds for every 10° F of
temperature change.
2. Remove the cap from the valve on one
tire.
3. Firmly press a tire gauge onto the valve
and record reading.
4. Add air to achieve recommended air
pressure.
5. If the tire is over filled, release air by
pushing on the metal stem in the center
of the valve. Recheck the pressure with
the tire gauge.
6. Replace the valve cap.
7. Repeat with each tire.
8. Visually
inspect
all the tires for nails or
other objects that could be embedded
or puncture the tire and cause an air
leak.
9. Check the sidewalls for gouges, cuts,
bulges, or other irregularities.
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.
