TRAILER TONGUE WEIGHT CALCULATOR — VERIFY YOUR SETUP
Enter hitch weight and trailer setup. Verify your bumper pull tongue weight is within safe limits instantly.
Bumper Pull Trailer Tongue Weight Calculator
Bumper pull trailers are the most common — and the most commonly overloaded. Get the tongue weight right before you tow.
Enter gross trailer weight and axle position. The calculator returns tongue weight, checks it against your truck’s hitch ball rating, and flags overload risk.
A bumper pull hitch ball rated at 500 lbs tongue weight can’t safely haul a trailer that puts 800 lbs on the ball. The rating is the limit.
Anyone towing a conventional bumper pull trailer, camper, or boat on a standard hitch ball.
- SAE J2807
- FMCSA towing regulations
