Monaco 2002 Diplomat, Service Manual

Page: 47 / 324

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: Improperly inflated tires can affect recreation-
al vehicle handling or may fail suddenly, possibly resulting
in loss of vehicle control. Use an accurate tire pressure
gauge.
Federal law requires that the specifications for the tire’s maximum load rat-
ing be molded into the sidewall of the tire. The amount of air pressure to use
is dependent on the weight of the motorhome when it is fully loaded. The
chart within this section shows weights that can be supported by various air
pressures. Utilizing less air pressure means a lesser load can be carried by the
tire.
Always comply with the tire manufacturer's recommended pressure infla-
tion guideline. The actual weight of the motorhome can vary significantly
depending on how it is loaded. Periodic adjustment to comply with the tire
manufacturer's guideline will provide for the optimum ride and handling. A
tire inflation chart listing proper inflation for different loading conditions of
various size tires is contained in this section of the manual.
Monaco Coach inflates the tires of the motorhome to pressure(s) appro-
priate for the actual weight on each axle in the unloaded, shipped condition.
When the motorhome is loaded, it is important to check and adjust the infla-
tion pressure on each tire as needed.
Always inflate tires at a pressure high enough to handle the actual load on
the tires. DO NOT OVERINFLATE 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 federal certification label recommended tire
inflation pressure(s). When loading a motorhome never exceed the
motorhome's 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.
