TIREs
Maintaining proper tire inflation pressure
is one of the most critical aspects of travel.
Improper pressure will lead to abnormal
wear and/or sudden tire failure. All tire
positions must be weighed separately with the
motorhome fully loaded 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 air pressure across the
axle 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
grip.
Belts: Stabilize and strengthen the
tread.
Sidewall:
Protects the side of the tire
from road and curb damage.
Body Ply: Provides tire strength and
flexibility.
Bead:
Assures an air-tight fit with the
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.
Driving on a tire without the correct inflation
pressure for the load of the motorhome is
dangerous and may cause premature wear,
tire damage and/or loss of control of the
motorhome.
An under-inflated tire will build up excessive
heat that may go beyond the design limits of
the rubber and radial cords and could result
in sudden failure. An under-inflated tire will
also cause poor motorhome handling, rapid
and/or irregular tire wear and an increase in
rolling resistance that results in decreased fuel
economy.
An over-inflated tire will reduce the tire’s
footprint/contact patch with the road, thus
reducing traction, braking capacity and
handling of the motorhome. Over-inflation of
a tire for the load will result in a harsh ride,
uneven tire wear and is susceptible to impact
damage. Maintaining correct tire inflation
pressure for each loaded wheel position on
the motorhome is of the utmost importance
and must be a part of regular motorhome
maintenance.
WARNING
Driving on a tire that is under-inflated
can exceed the design limits of the
tire and may damage the sidewall.
A damaged sidewall can burst upon
inflation resulting in serious damage,
injury or death. Aged tires are also
susceptible to sidewall damage.
Tire Pressure Inflation Guideline
Federal law requires that the specifications
for the tire’s maximum load rating be molded
into the sidewall of the tire. The amount of air
pressure to use is dependent on the weight of
the motorhome when fully loaded. The tire
chart indicates the weights that can be properly
supported by varying air pressures. Decreasing
air pressure decreases load carrying capacity.
Always comply with the tire manufacturer’s
recommended pressure inflation guideline.
The actual weight of the motorhome can vary
significantly depending on how it is loaded.
For optimum tire wear, ride and handling
always comply with the manufacturer
guideline.
A tire inflation chart listing proper inflation
pressure for different loads can be found in this
section. Tires on the motorhome are inflated to
pressure(s) appropriate for the actual weight on
each axle in the unloaded, shipped condition.
When the motorhome is loaded, check and
adjust the inflation pressure on each tire as
needed. Always inflate tires to the pressure
indicated in the tire chart for the load carried
by the tire.
WARNING
DO NOT OVERINFLATE OR
UNDERINFLATE THE TIRES.
The Gross Axle Weight Rating (GAWR) of
the axles listed on the federal certification label
attached to the motorhome is the maximum
allowable loaded weight on an axle. When the
actual loaded weight of the motorhome and
the weight on each axle is unknown, follow
the recommended tire inflation pressure(s)
listed on the federal certification label.
