Tire Pressure Inflation Guideline; Weight Terms - Holiday Navigator 2003 Owner's Manual

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 is contained in this section of the manual.
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'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.
The GVWR (Gross Vehicle Weight Rating) and GAWR (Gross Axle
Weight Rating) stickers on the motorhome (normally located on the support
pillar next to the driver's seat) will show the chassis manufacturer's and/or
the RV manufacturer's total vehicle maximum weight ratings and per axle
weight rating.
The GVWR is the maximum total weight for which the motorhome is rated –
including passengers, fluids and cargo. The GAWR is the maximum for which a
single axle is designed. These per axle and total maximum weight ratings
could be limited by the tires, wheels, axle and axle bearings, the motorhome
frame or other components of the motorhome.
The GAWR sticker is only a guide in knowing the maximum loaded axle
weights, and subsequently the correct tire inflation pressure. Every recreational
vehicle, even of the same make and model, will vary in actual loaded axle
weights because of different options and personal loads.
While the actual loaded axle weight should be below the GAWR, the
motorhome must be weighed in a loaded condition to know its actual weight.
Weigh the front axle, the total unit and the rear axle. It is possible for a
motorhome to be within the GVWR yet overloaded on an axle. It is even possible
for one wheel position to be overloaded, even though the GAWR has not been
exceeded. For this reason (if there is room to the sides of the scales) weigh
each wheel position of the motorhome.
