Refer to local laws for maximum trailer towing speeds.
NOTE:
•
The trailer tongue weight must be considered as part of
the combined weight of occupants and cargo, and
should never exceed the weight referenced on the Tire
and Loading Information placard. Refer to “Tire–Safety
Information” in “Starting and Operating” for further
information.
• Chrysler Group LLC does not recommend using the
run flat feature while driving a vehicle loaded at full
capacity or towing a trailer.
Trailer And Tongue Weight
Always load a trailer with 60% of the weight in the front
of the trailer. This places 10% of the GTW on the tow
hitch of your vehicle. Loads balanced over the wheels or
heavier in the rear can cause the trailer to sway severely
side to side which will cause loss of control of the vehicle
and trailer. Failure to load trailers heavier in front is the
cause of many trailer collisions. Never exceed the maxi-
mum tongue weight stamped on your trailer hitch.

a flat front tire, move the rear tire to the front and use the
spare tire on the rear.
