How tongue weight works
Tongue weight affects both stability and the tow vehicle’s payload. It should be measured for the trailer as actually loaded.
What tongue weight means
Tongue weight is the downward force the trailer applies at the hitch. It counts against the tow vehicle’s payload and must remain within the ratings of the receiver, ball mount, ball, vehicle, and related equipment.
Planning ranges are not universal limits
Conventional travel and cargo trailers are often planned around 10–15% of loaded trailer weight, while boat trailers may use a lower range such as 5–10%. The exact trailer and manufacturer instructions control.
Too little or too much
Too little tongue weight can contribute to sway. Too much can overload the hitch, rear axle, tires, or vehicle payload and can adversely affect steering and braking balance.
Measure loaded
Fuel, water, batteries, coolers, luggage, and the fore-aft position of cargo can change tongue weight. Measure the trailer in trip-ready condition with an appropriate scale or professional weighing process.
