Appendix B
Weight Distribution
Weight Distribution with Body
Chassis Weights
Step 2. In the following example, a truck is modified to include a van body mounted to the chassis. This example is a
chassis, 214 inches (5435.6 mm) in WB, with a standard drivetrain and fuel tank. It is a 26,000 lb. GVWR with a 8,948 lb.
front axle and a 17,052 lb. rear axle.
When calculating weight distributions, start by determining chassis ground weights for each axle. The actual chassis
weight will vary with the wheelbase and the options installed. Listed in Tables B-1 and B-2 are the chassis tare weights
for the standard single rear axle vehicles and each wheelbase configuration.
We see that the 214-inch wheelbase, 2-axle has the following tare weights:
FA = 6263.4
RA =
9628.7
Model 220 with nominal weights and CGs. See your Peterbilt Dealer for more exact weights and CGs. It also lists
their added weight when installed on the chassis and the location (from the front axle) of the CG of this added
weight.
