What can your car legally tow, and is that the same as what it can safely tow? Do you know the difference between gross train weight and payload, or has nobody ever explained it? The Trailer Towing Weight Explainer takes the numbers off your plate, your handbook and your trailer and explains what they actually mean for the trip you are planning.
Short answer: The Trailer Towing Weight Explainer is a free EizTools tool that explains towing weights in plain language, covering kerb weight, gross vehicle weight, gross train weight, noseweight and payload, and how they limit what you can tow.
What is Trailer Towing Weight Explainer?
It is an explainer for the most confusing part of towing. You give it the figures you have found. The Trailer Towing Weight Explainer tells you what each one means, which limit binds first, and where the margin is once the car and trailer are actually loaded.
How Does Trailer Towing Weight Explainer Work?
Put the numbers into the prompt box exactly as they appear: kerb weight 1,680kg, gross vehicle weight 2,250kg, gross train weight 3,750kg, braked towing capacity 1,800kg, caravan MIRO 1,240kg with MTPLM 1,450kg, towball noseweight limit 90kg, two adults and luggage in the car.
Pick a model, then set the options. Depth on Standard is right for a single setup. Angle on Cost-Benefit is not what you want here, so use Feature Comparison when you are weighing two trailers, or Use-Case Fit when you are asking whether one specific combination works. Output Format on Structured Sections keeps definitions and calculations apart, and Audience Level should stay on General.
Press Generate. The explanation appears in the output card with a word count and reading time, and you can download it as TXT or Word to keep with the vehicle documents. Your previous runs remain listed while the tab is open, so two trailers can be explained one after the other.
Terms untangled
Kerb weight, MIRO, MTPLM and gross train weight explained in ordinary words.
Noseweight covered
The limit people forget, and the one that makes a trailer feel unstable when it is wrong.
Which limit binds
It names the figure that runs out first, which is usually not the one you were watching.
Who Should Use It?
- First time caravanners working out whether their car is suitable
- Anyone hiring a trailer for a house move or a garden clearance
- Drivers whose licence category limits what they may tow
- Small traders towing plant, mowers or a small digger
| Figure | What it limits |
|---|---|
| Gross vehicle weight | The loaded car alone, including passengers and noseweight |
| Gross train weight | Car and trailer together, fully loaded |
| Braked towing capacity | The heaviest braked trailer the car is approved to pull |
| Noseweight limit | The downward load allowed on the towball |
Important The plate on your vehicle and the figures in your handbook are the authority, not an explanation. Weigh the loaded outfit on a public weighbridge if you are anywhere near a limit, because being over is both an insurance and a legal problem.
Best Use Cases
The explanation is most useful before you buy, when you are deciding whether a particular caravan or trailer suits the car you already own. It is also worth running before a long trip, when the load has grown since last season. If your handbook section is long and full of tables, put it through the Text Summarizer first, then bring the key figures back here for the explanation.
EizTools does not charge, does not meter, and does not ask you to join. Pick which AI model family answers from the selector before generating, and rerun the same figures at greater depth if the first answer moves too quickly. Every tool has advanced options built for its own job rather than one shared panel across the site.
Frequently Asked Questions
Does the Trailer Towing Weight Explainer give legal towing limits?
It explains how the limits work. The binding figures come from your vehicle plate, your handbook and your licence category, and those are what you must follow.
What is noseweight and why does it matter?
It is the downward force the trailer puts on the towball. Too little makes the trailer unstable, too much overloads the rear axle and the towbar.
Does my driving licence limit what I can tow?
Often yes, depending on when you passed and where. Say your licence category in the brief and check the current rules with your licensing authority.
How do I know my real loaded weight?
Weigh it. A public weighbridge gives you the actual figures for car and trailer as loaded, which estimates rarely match.
Can it compare two trailers for my car?
Yes. Give both sets of figures in the same brief and set the angle to Feature Comparison, and the explanation shows which one fits your limits.
Towing goes wrong when people watch one number and ignore the three that matter more. Put your real figures in above, find out which limit binds first, then weigh the outfit loaded before a long trip. It is a twenty minute job that removes the doubt entirely.
