Tongue weight is the downward force exerted by a trailer’s tongue on the hitch of the towing vehicle. It is generally expressed as a percentage of the gross trailer weight (GTW), typically between 10% and 15%. For instance, a trailer with a GTW of 5,000 pounds should ideally have a tongue weight between 500 and 750 pounds.
Maintaining proper tongue weight is crucial for safe and stable towing. Insufficient tongue weight can lead to trailer sway, a dangerous condition where the trailer oscillates uncontrollably. Excessive tongue weight, on the other hand, can overload the rear axle of the tow vehicle, negatively impacting handling and braking performance. Historically, improper weight distribution has been a significant contributing factor to towing-related accidents, underscoring the importance of accurate measurements and adjustments.
