If you’re planning to haul a trailer, boat, or camper, one of the first things to figure out is your vehicle’s towing capacity. But a common question people have is:
“Does towing capacity include the trailer weight?”
The answer is: Yes, towing capacity does include the weight of the trailer—along with anything you’re carrying inside it.
Let’s break down what this means and how to calculate your towing needs safely.
What Is Towing Capacity?
Towing capacity is the maximum amount of weight your vehicle can safely tow as specified by the manufacturer. This number takes into account:
- Engine power
- Transmission strength
- Axle ratios
- Brakes
- Suspension
- Cooling systems
It’s based on lab testing and safety margins, and exceeding it can cause serious damage to your vehicle—or worse, lead to accidents.
Does It Include the Trailer Weight?
Yes. Your towing capacity includes:
- The weight of the trailer itself (also called curb weight or empty weight)
- Any cargo, equipment, or supplies loaded into the trailer
For example, if your vehicle’s towing capacity is 6,000 lbs, that’s the total you’re allowed to tow—including the trailer and everything inside it.
Key Terms to Know
1. GVWR (Gross Vehicle Weight Rating)
The max weight your vehicle can weigh with passengers, cargo, and tongue weight—but not including a trailer.
2. GCWR (Gross Combined Weight Rating)
The max total weight of your vehicle + trailer + all cargo.
This is often more useful than towing capacity alone.
3. Curb Weight
Your vehicle’s weight with all fluids, but no passengers or cargo.
4. Tongue Weight
The amount of weight the trailer puts down on the hitch—usually 10–15% of the trailer’s total weight.
How to Calculate What You Can Tow
Let’s say your vehicle’s towing capacity is 7,500 lbs.
If Your Trailer:
- Weighs 2,500 lbs empty
- Carries 3,000 lbs of gear, ATVs, or supplies
Total trailer weight = 5,500 lbs
You’re under your limit, so you’re good.
But if you add more cargo or water tanks that push the trailer to 8,000 lbs, you’d now be over your towing capacity—even if your vehicle seems to “handle it fine” on flat ground.
Why Staying Under Towing Capacity Matters
- Braking distance increases with more weight
- Transmission stress and overheating become risks
- Steering and handling can be affected
- Insurance claims may be denied if you’re towing beyond rated capacity
- Legal fines or penalties if you’re caught exceeding limits
FAQs
Is the trailer’s weight separate from the towing capacity?
No. Towing capacity is the total combined weight you’re allowed to pull, including the trailer and its cargo.
Can I exceed towing capacity if I only go short distances?
It’s not recommended. Even short trips can cause wear or damage—and it’s unsafe in emergency situations like sudden braking or swerving.
Does towing capacity include tongue weight?
Not directly. Tongue weight counts toward your vehicle’s GVWR (what the vehicle itself can carry), not towing capacity—but it’s still an important safety factor.
Final Thoughts
Yes, your towing capacity includes the trailer’s weight.
When planning any towing setup, you need to account for the full weight of the trailer plus everything inside it. Ignoring this can put stress on your vehicle, reduce control, and create dangerous driving conditions.
Always double-check your vehicle’s towing specs, stay under the limit, and tow smart—it’ll keep you safer and protect your ride in the long run.
