TIREs
Maintaining proper tire inflation pressure
is important for proper tire load carrying
capacity and wear. Improper pressure will lead
to abnormal wear and/or sudden tire failure.
Weigh the motorhome fully loaded for travel
to determine proper tire inflation pressure. If
one tire position on the axle is heavier than
the other side, inflate both sides according to
the heaviest side. This will provide correct
tire inflation pressure across the axle and
provide stability while cornering. To obtain the
maximum wear and best service from tires, it
is helpful to understand their components and
functions.
Tire Components:
Tread:
z
Provides traction and cornering
grip.
Belts:
z
Stabilize and strengthen the
tread.
Sidewall:
z
Protects the side of the tire
from road and curb damage.
Body Ply:
z
Provides tire strength and
flexibility.
Bead:
z
Assures an air-tight fit with the
wheel.
Inner Liner:
z
Keeps air inside the tire.
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.
z
Separations.
z
Rapid and uneven wear on the edges of
z
the tread.
Circumferential breaks.
z
Tire container may bruise or rupture.
z
Higher risk of road hazard.
z
Tire cord breakage.
z
Loss of casing durability.
z
Excessive tire temperature.
z
High fuel consumption.
z
Reduced handling quality.
z
Overinflation can cause:
Hard ride.
z
Tire bruising or carcass damage.
z
Rapid tread wear in the center of the
z
tire.
Unequal Tire Pressures on the Same Axle
Causes:
Uneven braking.
z
Swerve upon acceleration.
z
Torque steer.
z
Reduced handling quality.
