Four Corner Weighing (Example)
NOTE
Following scale readings and Gross Axle
Weight Ratings are fictitious. Actual
scale readings and Gross Axle Weight
Ratings will vary with model and
options.
The motorhome must be weighed fully
loaded to obtain accurate scale readings and
to determine the proper tire pressure. All slide
rooms must be in retracted position.
Take the rear axle
Gross Axle Weight
Rating (GAWR)
and divide it by two.
Example: Rear axle
GAWR
taken from
the motorhome Vehicle Certification
Label is 14,500 lbs. Divide the figure by
2, using chart below, record 7,250 lbs. on
Scale B and D, line 1.
Weigh the driver side rear corner (Scale
B) and record weight on chart Scale B,
line 2. Example: 4,400 lbs.
Weigh the passenger side rear corner
(Scale D) and record weight on chart
Scale D, line 2. Example: 4,100 lbs.
Add chart Scale B and D, lines 1, for
Gross Axle Weight Rating (GAWR)
and record on chart under Totals.
Example: 14,500 lbs.
Add chart Scale B and D, lines 2, for
actual
Gross Axle Weight (GAW)
and
record on chart under Totals. Example:
8,500 lbs.
Actual Gross Axle Weight (GAW)
.
Example: 8,500 lbs., is not to exceed
Gross Axle Weight Rating (GAWR)
.
Example: 14,500 lbs.
Refer to the Example Tire Chart (Tire
size 275/70R22.5). Use the highest actual
weight, Scale B or D, line 2. Example
4,400 lbs. Determine the proper tire
pressure for each tire using the Load
Inflation chart. Example: 95 psi or stamp
on the sidewall of the tire.
Repeat above procedures to determine
front axle Scale A and C, tire pressures.
WARNING
Improperly inflated or overloaded tires
can cause a blowout. An overloaded
axle can cause a component failure of
the suspension system. Tire blowout
or broken suspension components can
lead to loss of vehicle control resulting
in property damage, personal injury or
death.
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.
