Tire Pressure - Monaco DIPLOMAT 2004 Owner's Manual

DIPLOMAT 2004
2 • 86
The following is an explanation of commonly used weight abbreviations.
• Gross Vehicle Weight Rating (GVWR):
Maximum permissible weight of this motorhome. GVWR is
equal to or greater than the sum of UVW plus CCC.
• Unloaded Vehicle Weight (UVW):
Weight of this motorhome as built at factory with full fuel,
engine oil and coolants. UVW does not include cargo, fresh
water, LP-Gas, occupants or dealer installed accessories.
• Cargo Carrying Capacity (CCC):
Equal to GVWR minus each of the following: UVW, full fresh
potable water weight (including water heater), full LP-Gas
weight, and SCWR. Tongue weight of towed vehicle and dealer
installed equipment will reduce CCC.
• Gross Combination Weight Rating (GCWR):
The maximum allowable loaded weight of this motorhome and
any towed trailer or towed vehicle
• Gross Axle Weight Rating (GAWR):
Load-carrying capacity specified by manufacturer of a single
axle system, as measured at tire ground interfaces.
• Sleeping Capacity Weight Rating (SCWR):
The manufacturer's designated number of sleeping positions
multiplied by 154 pounds.

Tire Pressure:

A motorhome may weigh slightly heavier on one side than on the other.
Tire inflation pressure of the heavier side tires determine the inflation
pressure for all tire(s) on that axle due to the weight transfer that occurs
when cornering. The weight load will be transferred on the opposite side
from the direction in which the motorhome is cornering.
Improperly inflated tires, or suspension that is incorrectly loaded, can
result in poor fuel economy, poor handling and over-stressed chassis
components. Vehicle loading will influence tire inflation pressure and the
load carried by each axle. This is why each wheel position must be weighed.
Motorhome axle configuration and floor plan styles will require different
weighing procedures.
NOTE: When weighing a motorhome, each tire on any axle must
be inflated to the same pressure. The wheel position carrying the
most weight will determine the tire inflation pressure for each tire
of that particular axle.
