Importance Of Air Pressure; Tire Inflation Information - Fleetwood Discovery Owner's Manual

Importance of Air Pressure

The most important factor
in maximizing the life of the
tires is maintaining proper
inflation pressure. Driving with
an underinflated or overinflated
tire is dangerous and may cause
premature wear, tire damage,
sudden tire failure that can result in
loss of control of the motorhome.
A tire that is underinflated will
cause excess heat that can exceed
operating limits of the tire and
could result in sudden failure and
fire. An underinflated tire will also
cause poor handling, rapid and/or
irregular tire wear and increases
rolling resistance and decreases
fuel economy.
WARNING:
Driving on a tire that is
underinflated can exceed
the design limits of the
tire and may damage
the sidewall. A damaged
sidewall can suddenly burst
upon inflation resulting
in serious damage, injury
or death. Aged tires are
also susceptible to sidewall
damage.
A tire that is overinflated will
reduce the footprint/contact patch
with the road reducing traction,
brake effectiveness and handling.
Overinflation will also cause
a harsh ride, uneven tire wear
and make the tire susceptible
to impact damage. Maintaining
correct inflation pressure is of
utmost importance for safety and
reliability and should be a part of
regular maintenance checks.
Underinflation can cause:
Tire squeal on turns.
‹
Separations.
‹
Rapid and uneven wear on
‹
the edges of the tread.
Circumferential breaks.
‹
Tire container may bruise
‹
or rupture.
Higher risk of road hazard.
‹
Tire cord breakage.
‹
Loss of casing durability.
‹
Excessive tire temperature.
‹
High fuel consumption.
‹
Reduced handling quality.
‹
Overinflation can cause:
Hard ride.
‹
Tire bruising or carcass
‹
damage.
Rapid tread wear in the
‹
center of the tire.

Tire Inflation Information

Federal law requires the size
of the tire, the tire's maximum
inflation pressure and load
capacity as well as load range be
molded into the sidewall of the
tire. Inflation pressure will vary
dependent upon the weight of the
motorhome when fully loaded
ready for travel. Always comply
with the tire manufacturer's
recommended inflation pressure.
This requires the motorhome be
weighed in a loaded, ready to
travel condition, to determine
actual weight carried by the tires.
Actual weight of the motorhome
can vary significantly depending
on how it is loaded. For optimum
tire wear, ride and optimum
handling always comply with the
manufacturer's suggested inflation
pressure for the actual weight
of the motor home. From the
factory, the tires are inflated to the
maximum pressure.
When the motorhome is loaded
ready for travel, check and adjust
inflation pressure on each tire
as indicated in the load inflation
table.
