TOWCHECK FIELD GUIDE
Tongue weight explained
Tongue weight is the downward trailer load carried at a conventional hitch. It consumes tow-vehicle payload and receiver capacity and can change materially when cargo, tanks or accessories move.
What the terms mean
Tongue-weight percentage divides measured or estimated tongue load by loaded trailer weight. Manufacturer guidance for the exact trailer and tow vehicle controls; a generic percentage is only a planning input.
Worked example
Common mistakes
- Applying a percentage to dry weight
- Using the brochure hitch figure after loading
- Assuming a favorable percentage guarantees stable handling
Frequently asked questions
Is 10–15% universal?
No. It is commonly referenced for conventional trailers, but trailer and vehicle documentation controls.
Does weight distribution remove tongue weight?
No. It changes axle-load distribution; it does not make the applied load disappear.
When should I remeasure?
After meaningful changes to cargo placement, tank levels or installed equipment.
