•Payload:Combined maximum allowable weight of cargo, occupants
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.
•GVW (Gross Vehicle Weight):Base curb weight plus payload
weight. The GVW is not a limit or a specification.
•GVWR (Gross Vehicle Weight Rating):Maximum permissible total
weight of the base vehicle, occupants, optional equipment and cargo.
The GVWR is specific to each vehicle and is listed on the Certification
Label, located near the driver’s seat or on the driver’s door pillar.
•GAWR (Gross Axle Weight Rating):Carrying capacity for each axle
system. The GAWR is specific to each vehicle and is listed on the
Certification Label, located near the driver’s seat or on the driver’s
door pillar.
•GCWR (Gross Combined Weight Rating):Maximum permissible
combined weight of towing vehicle (including occupants and cargo)
and the loaded trailer.
•Maximum Trailer Weight Rating:Maximum weight of a trailer the
loaded vehicle (including occupants and cargo) is permitted to tow.
The maximum trailer weight rating is determined by subtracting the
vehicle curb weight for each engine/transmission combination, any
required option weight for trailer towing and the weight of the driver
from the GCWR for the towing vehicle.
•Trailer Weight Range:Specified weight range that the trailer must
fall within that ranges from zero to the maximum trailer weight rating.
Remember to figure in the tongue load of your loaded trailer when
figuring the total weight.
Exceeding any vehicle weight rating limitation could result in
serious damage to the vehicle loss of vehicle control, vehicle
rollover, and/or personal injury.
Do not use replacement tires with lower weight capacities than the
originals because they may lower the vehicle’s GVWR and GAWR
limitations. Replacement tires with a higher weight limit than the
originals do not increase the GVWR and GAWR limitations.
