B Gross Axle Weight (GAW) and Gross Axle Weight Rating
(GAWR)
The total weight applied to each axle (GAW) must never exceed the
Gross Axle Weight Rating (GAWR). The front and rear GAWs can be
adjusted by relocating passengers and luggage inside the vehicle.
The front and rear GAWR are also shown on the certification label.
Gross Axle Weight
To check both GVWR and GAWR and to confirm that the total weight
and weight distribution are within safe driving limits, you should have
your vehicle and trailer weighed at a commercial weighing station.
Be sure that all cargo is firmly secured to prevent a change in weight
distribution while driving.
n Tongue load
WARNING
If the trailer is loaded with more weight in the back of trailer's
axle than in the front, the load is taken off the rear axle of the tow-
ing vehicle. This may cause the rear wheels to skid, especially
during braking or when vehicle speed is reduced during corner-
ing, resulting in over-steer, spin out and/or jackknifing.
Ensure that the trailer tongue load is from 8 to 11 percent of the total
trailer weight and does not exceed the maximum value of 200 lbs (90
kg).
The tongue load can be weighed with a bathroom scale as shown in
OM-H2784
