DRIVING & SAFETY - 2
CAYMAN 2007

CAUTION:
If actual weight carried by any tire is
below the tire chart weight specification
minimum tire pressure the minimum
inflation pressure must be maintained.
Tire pressure below the minimum
inflation pressure can overheat and
damage the tire casing leading to
premature tire failure or blowout.
Load and Infl ation Tables:
The Load and Infl ation Table will help
determine correct infl ation for the motorhome
tires after properly weighing the motorhome. All
pressures are rated at a cold PSI. Cold conditions
are defi ned as early in the morning before the
day’s ambient temperature, sun’s radiant heat or
the heat generated while driving have caused the
tire pressure to temporarily increase. This means
that the pressure should be checked early and
when the motorhome has not been driven more
than one mile. The check interval should be in
the morning, before the “drive” trip and every
morning on extended trips. A quality truck tire
gauge with a multiple angle airhead is needed
to ensure access to both dual wheel positions of
the drive axle. Ensure the valve cap is replaced
on the stem after the infl ation is checked. This
guarantees the valve core will remain free of dirt
and foreign material. Material lodged between
the valve core and internal stem can cause slow
leaks resulting in tire failure.
Cargo Carrying Capacity:
When weighing the motorhome it is important
to understand that each motorhome, even of
the same model year, fl oorplan and length will
weigh different due to options and accessories.
The Gross Vehicle Weight Rating ( GVWR ),
Gross Combination Weight Rating (GCWR)
and/or Gross Axle Weight Rating (GAWR) must
not be exceeded.
GVWR of the vehicle limits the weight of the
entire load combination, regardless of the water,
LP-Gas, passengers and cargo weight.
It is important to understand that the weighing
process is performed in two phases. First, by
determining the Cargo Carrying Capacity
(CCC) ; and second, to ensure the GVWR is
not exceeded when adjusting tire pressures. The
weighing process should start by recording the
GVWR from the Federal Weight Label, then
weighing the motorhome unloaded, without
passengers and with a full fuel tank. Engine and
transmission fl uid levels must be full. This is
known as the Unloaded Vehicle Weight ( UVW ).
Once this weight has been recorded it can be
subtracted from the GVWR .
