Tongue Load
The weight of the tongue with a fully loaded trailer on the hitch should be
approximately:
Boat trailers: 5% - 15% of the total
trailer weight.
Other trailers: 10% – 15% of total
trailer weight

• If you cannot weigh the rear axle, subtract 1 from 2.
• The maximum gross combined weight (4) decreases by 2% for every
1,000 feet (305m) of elevation.
• To calculate the tongue load, subtract 5 from 6.
• Refer to the trailer owner's manual for additional information.
Note: If a public scale is not available, add the estimated weight of your
cargo load to the weight of your trailer (as quoted by the manufacturer),
and then measure the tongue load with an appropriate scale or tongue
gauge or estimate it based on cargo distribution.
