Tires - Holiday Admiral 2016 Manual

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: Provides traction and cornering
z
grip.
Belts:
Stabilize and strengthen the
z
tread.
Sidewall:
Protects the side of the tire
z
from road and curb damage.
Body Ply:
Provides tire strength and
z
flexibility.
30
Bead: Assures an air-tight fit with the
z
wheel.
Inner Liner: 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
090438 safety and reliability and should be a part of
regular maintenance checks.
