If you’re planning to tow a trailer or haul any heavy load with your vehicle, there’s one crucial thing you need to know first: your towing capacity.
Exceeding your vehicle’s tow limit can lead to serious problems like accidents or major damage.
But don’t worry—finding out your maximum safe towing weight is pretty simple! All you need is your vehicle’s VIN number.
In this guide, we’ll walk you through exactly how to use your VIN to check your vehicle’s towing capacity quickly and easily. By the end, you’ll be ready to hitch up and hit the road with confidence!
How to Check Towing Capacity by VIN?
What exactly is towing capacity?
It’s the maximum amount of weight your car or truck can safely pull. Knowing this is super important for two big reasons:
- You don’t want to damage your vehicle by trying to tow too much
- You want to stay safe on the road and not cause any accidents
The good news is, there’s an easy way to find out your vehicle’s towing capacity. All you need is the VIN number.
What is a VIN Number?
VIN stands for Vehicle Identification Number. Every vehicle has its own unique VIN. It’s like a code that tells you all sorts of details about the car or truck, including the towing capacity.
In this article, we’ll walk you through exactly how to use the VIN number to check your vehicle’s tow rating.
We’ll cover:
- What towing capacity means.
- The difference between towing capacity and gross vehicle weight rating (GVWR).
- How to calculate your vehicle’s safe towing limit.
- The towing capacity formula.
- What a VIN number is and how to decode it.
- Where to find the VIN on your vehicle.
By the end, you’ll be a towing capacity expert! Let’s dive in.
What Does Towing Capacity Mean?
Towing capacity is the total weight your vehicle can handle pulling behind it. This includes:
- The weight of the trailer or item you’re towing.
- Any cargo, passengers, or fuel in what you’re towing.
If you go over your vehicle’s rated towing limit, some not-so-good things can happen:
- Your engine could overheat
- The transmission could get damaged
- You might lose control of the vehicle
- Parts could even break
So it’s important to stay within the safe towing capacity!
How much your vehicle can tow depends a lot on what kind of vehicle it is.
Things like the size of the engine, type of transmission, and even whether it runs on gas or diesel all make a difference.
In general, trucks can pull heavier loads than cars. Diesel engines tend to have higher tow ratings than gas ones.
But every vehicle is different. That’s why you need to check the specific rating for yours.
GVWR vs Towing Capacity
Now, there’s another important term to know here: Gross Vehicle Weight Rating or GVWR.
What’s the difference between GVWR and towing capacity?
GVWR is the maximum weight your vehicle itself can handle, including:
- The weight of the vehicle (this is called the “curb weight”).
- Any passengers.
- Any cargo you’re hauling in the vehicle.
Towing capacity, on the other hand, only refers to how much it can pull behind it. It doesn’t include the vehicle’s weight.
There’s also something called the Gross Combined Weight Rating (GCWR).
This is the maximum allowed weight of your fully loaded vehicle plus anything it’s towing.
So when you’re figuring out how much you can safely tow, you need to keep all three ratings in mind:
| Rating | What It Means |
|---|---|
| GVWR | Max vehicle weight including itself, passengers, cargo |
| Towing Capacity | Max weight vehicle can tow behind it |
| GCWR | Max combined weight of vehicle + towed load |
Your owner’s manual should have all these listed. If not, a service shop can help you calculate them.
Calculating Your Vehicle’s Towing Capacity
Okay, so how do you figure out your vehicle’s safe tow limit?
Here’s what you need to know:
- Your vehicle’s GVWR
- Its curb weight
- The weight of passengers and cargo you’ll be carrying
- The Gross Axle Weight Rating (GAWR) – this is the maximum weight each axle can support
A good ballpark towing capacity formula is:
- Towing Capacity = GVWR – (Curb Weight + Passenger Weight + Cargo Weight)
But this is just an estimate. To get the most accurate number, you should check your owner’s manual or contact your vehicle manufacturer. The total safe tow limit also depends on GCWR, not just GVWR.
The Importance of the VIN Number
This is where the VIN number comes in so handy. The VIN has detailed info about your specific vehicle, including the towing capacity straight from the manufacturer.
You can use the VIN to access a big list of your vehicle’s “specs” like:
- What size the engine is
- What type of transmission it has
- If it came with a special towing package installed
- The exact GVWR and sometimes GCWR too
All of these specs together determine your vehicle’s true towing power. And the VIN is the key to unlocking all that information.
How to Decode the VIN?
Every VIN is 17 digits long. And each digit or group of digits means something different about the vehicle.
The first digits tell you the country and manufacturer. The middle ones are details like the engine and body style. The last ones are the production number and model year.
But you don’t have to be a code-cracking expert to figure it all out. You can use an online VIN decoder tool or contact a dealer to translate all the details for you.
Just enter your VIN, and it will spit out a full “profile” of your vehicle. This will include the maximum safe towing weight if your vehicle is rated for towing.
Where to Find Your VIN Number?
So where do you look to find your VIN? It’s printed in several places:
- On the driver’s side dashboard, visible through the windshield.
- On a sticker on the driver’s side door or door jamb.
- On the engine block or near the front of the engine bay.
- On your vehicle registration and insurance documents.
It’s usually easiest to find the VIN on the dashboard or door sticker.
Once you have the VIN in hand, you can either:
- Contact your vehicle manufacturer with the VIN to ask for the towing specs
- Use an online VIN decoder to look up the details yourself
- Take the VIN to a dealership and have them look it up for you

Conclusion:
To sum it all up, here are the key things to remember about towing capacity and VIN numbers:
- Towing capacity = the max weight your vehicle can safely tow behind it.
- Staying within the tow limit is critical for your safety and to prevent damage.
- Towing capacity is different from gross vehicle weight rating (GVWR).
- The VIN number contains detailed specs that determine the towing capacity.
- You can decode the VIN yourself or have a dealer do it to find the tow rating.
- The VIN is printed in several places on the vehicle itself and registration/insurance docs.
By finding your VIN number and decoding it, you can quickly figure out exactly how much your vehicle can handle towing. No more guesswork or worrying about causing damage or being unsafe!
Knowing your vehicle’s true limits allows you to choose the right trailer or towing setup for your needs. And then you can hit the road with total confidence, knowing you’re well within the safety zone.
So the next time you need to tow something, remember: Check the VIN, stay within the limit, and drive safe out there!
