Tires, wheels and loading – FORD 2012 F-550 v.1 User Manual

Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully prior to and after any towing operation. Refer to
Transmission fluid temperature gauge in the Instrument Cluster
chapter for the transmission fluid temperature information.
To find the maximum trailer weight allowed for your vehicle, consult
your authorized dealer (or the RV and Trailer Towing Guide provided
by your authorized dealer).
To calculate your maximum trailer weight on your own:
1. Pick-up trucks: Take curb weight, hitch hardware and the driver’s
weight, then subtract them from the GCWR listed for your vehicle
series and drive axle ratio listed on the following table.
2. Chassis cabs and pick-up trucks with aftermarket equipment:
Weigh your vehicle at a certified scale and subtract this actual curb
weight, hitch hardware and the driver’s weight from the GCWR listed
for your vehicle series and drive axle ratio listed on the following
table.
The weight of all additional cargo and passengers must be subtracted
from the maximum trailer weight calculated above.
Further trailer/hitch restrictions and limitations exist depending on the
type of trailer and hitch used. This information follows the table listing
the maximum GCWRs.
For load specification terms found on the label and instructions on
calculating your vehicle’s load, refer to Vehicle loading - with and
without a trailer in this chapter when figuring the total weight of your
vehicle.
Note: Do not exceed the tire ratings specified on the Tire Label or
Safety Compliance Certification Label.
WARNING: Do not exceed the GVWR or the GAWR specified on
the certification label.
WARNING: Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of the vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.
