Importance Of Air Pressure; Tire Pressure Inflation Guideline - Monaco 2009 Knight Owner's Manual

Importance of Air Pressure

The most important factor in maximizing
the life of the tires is maintaining proper
inflation. Driving on any tire that does not
have 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
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 a tire 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
recommended pressure inflation guidelines.
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
guidelines. A tire inflation chart listing proper
inflation pressure for different loads can be
found in this section.
The tires of 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. 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. When loading a motorhome
never exceed the motorhome Gross Vehicle
Weight Rating (GVWR) or the GAWR for
each axle.
Contact the tire manufacturer for further
information concerning proper tire pressure
inflation and other tire issues.
NOTE
The motorhome is equipped with
Goodyear 275/70R 22.5 G670 RV
Unisteel Radial, Load Range H tires at
the time of printing. The motorhome
manufacturer will not be responsible
for substitution of an incorrect tire
size or load range. Verify tire brand,
size and load range before obtaining
replacement tires.
