How to Measure Tongue Weight: Step by Step Guide
Understanding how to measure your trailer’s tongue weight is critical for safe towing. Incorrect tongue weight can cause sway, braking issues, and dangerous handling. Here’s a comprehensive guide to ensure you’re towing safely every time.
Quick-Start Checklist:
- Understand why tongue weight matters
- Gather necessary tools
- Follow step-by-step measurement guide
- Learn common mistakes
- Check FAQs for quick answers
Why Tongue Weight Matters
- Stability while towing
- Safe braking distances
- Prevention of dangerous trailer sway
Improper tongue weight can lead to accidents, premature vehicle wear, and even legal issues.
Tools You’ll Need
- Tongue weight scale, bathroom scale (for lighter trailers), or a hitch with a built-in scale (such as Weigh Safe’s Drop Hitch)
- Level surface for accurate measurement
- Trailer fully loaded as it would be during towing
- Lever and fulcrum setup (if using a bathroom scale)
Step-by-Step Measurement Guide
Step 1: Park on a Level Surface
Ensure your tow vehicle and trailer are on level ground for accurate readings.
Step 2: Position the Scale
Place your tongue weight scale beneath the trailer coupler. If using a Weigh Safe hitch, simply attach your trailer and read directly from the built-in gauge. If using a bathroom scale, set up your lever and fulcrum correctly.
Step 3: Measure Your Tongue Weight
Lower your trailer’s coupler onto the scale or hitch ball, ensuring the full weight is resting on it. Clearly read and record the displayed weight.
Step 4: Verify and Adjust
Refer to your trailer’s manual or vehicle towing specs. Adjust your load if your tongue weight is outside the recommended range (10-15%). Distribute heavier items closer to the trailer axle.
Common Mistakes & How to Avoid Them
Mistake 1: Measuring on Uneven Ground
Always use flat, level surfaces to ensure accuracy.
Mistake 2: Ignoring Load Distribution
Evenly distribute your cargo, placing heavier items near the trailer axle to adjust tongue weight effectively.
Mistake 3: Skipping Regular Checks
Recheck tongue weight frequently, especially after adjusting cargo or before long trips.
Lever Method for Light Trailers
If you’re using a bathroom scale, follow these steps:
-
Set up a sturdy lever (e.g., a 4-foot board) with a fulcrum placed one foot from one end.
-
Place the bathroom scale at the short end and a block at the other end.
-
Rest the trailer tongue on the lever directly above the fulcrum.
-
Multiply the scale reading by four to determine your tongue weight.
