How much your vehicle can tow: weights, ratings and the stickers to read
How to read your vehicle's weight ratings and check if a trailer is safe to tow
“Tows up to 10,000 pounds!” sounds simple. But that headline number assumes a nearly empty truck, the right equipment and a perfectly loaded trailer. Add a family, a cooler and a camper, and many drivers go over a limit without knowing it.
Overloaded tow vehicles take longer to stop, are harder to steer and are more likely to sway. This guide explains the weight ratings that matter and shows you how to check whether a trailer is safe to tow.
The ratings that matter
NHTSA’s towing guide defines the key terms [1]:
Comparison compiled by Safety Behind the Wheel Foundation
Towing weight terms in plain English
| Term | What it means |
|---|---|
| Gross vehicle weight rating (GVWR) | The most your tow vehicle may weigh, fully loaded, including passengers, cargo and tongue weight |
| Gross combination weight rating (GCWR) | The most the tow vehicle and loaded trailer may weigh together |
| Gross axle weight rating (GAWR) | The most each axle may carry |
| Payload | How much weight you can add to the tow vehicle: people, cargo and tongue weight |
| Tongue weight | The part of the trailer’s weight pushing down on the hitch |
| Towing capacity | The most trailer weight the maker says the vehicle can pull, under set conditions |

Where to find your numbers
- The tire and loading information sticker on the driver’s door frame says the combined weight of people and cargo should never exceed a certain number of pounds. That is your payload limit [2].
- The certification label, also on the door frame, lists GVWR and GAWR [1].
- The owner’s manual or the maker’s towing guide lists towing capacity and GCWR, often by engine, axle ratio and options.
- The hitch has its own weight limits stamped on it. Use the lowest limit of any part in the chain.
Payload is often the real limit
Tongue weight counts against your payload. For a regular bumper pull trailer, most vehicle makers advise tongue weight of about 10 to 15 percent of the loaded trailer weight. Fifth wheel and gooseneck trailers put even more weight on the truck.
Here is a simple example:
- Loaded travel trailer: 7,000 pounds
- Tongue weight at 12 percent: 840 pounds
- Four people in the truck: 600 pounds
- Cooler, bikes and gear in the bed: 250 pounds
- Total added to the truck: 1,690 pounds
If the door sticker says payload is 1,500 pounds, this setup is overloaded, even though the trailer is well under a 9,000 pound towing capacity.
Load the trailer right
Where weight sits matters. NHTSA warns that too little tongue weight can cause sway, and too much can lift weight off the front wheels and reduce steering [1].
- Put about 60 percent of the cargo in the front half of the trailer
- Keep heavy items low and centered
- Tie everything down so it cannot shift
- Weigh the full rig at a truck scale
Use the right equipment
- Hitch and ball rated for your trailer weight
- Weight distributing hitch for heavier trailers, if the maker recommends it
- Safety chains crossed under the trailer tongue, with enough slack to turn but not drag [1]
- Trailer brakes. Many states require separate brakes and a breakaway switch on loaded trailers over a set weight, often starting at 1,500 pounds [1]
- Brake controller in the tow vehicle for electric trailer brakes
- Tow mirrors if you cannot see down both sides of the trailer
- Matching tires in good shape and inflated to the listed pressure [1]
If the trailer starts to sway
Sway is a side to side motion that can grow until you lose control. It can start from high speed, a gust of wind, a passing truck or poor loading [1].
1. Take your foot off the gas.
2. Hold the steering wheel straight and firm.
3. If you have a brake controller, apply the trailer brakes alone by hand.
4. Do not slam the tow vehicle’s brakes. NHTSA warns this generally makes sway worse [1].
5. When it settles, pull over and check the load.
Warning: If your trailer sways more than once, stop and fix the cause. Reload the trailer, lower your speed or get a better hitch. Repeated sway is a warning sign of a serious crash.
Driving with a trailer
- Drive at moderate speeds. Sway gets more likely as speed rises [1]
- Leave much more stopping distance [1]
- Make wider turns so trailer wheels clear curbs [1]
- Pass only on level ground with lots of room [1]
- On long downhill grades, use a lower gear and brake in intervals [1]
Checklist: before you tow
Checklist from Safety Behind the Wheel Foundation
- I know my payload, GVWR, GCWR and towing capacity
- My total payload, including tongue weight, is under the door sticker limit
- Tongue weight is roughly 10 to 15 percent of the trailer weight
- The hitch, ball and chains are rated for this load
- Safety chains are crossed and trailer brakes work
- All lights and turn signals work on the trailer
- Tires on both vehicles are at the listed pressure
Frequently asked questions
Can I tow with an electric vehicle?
Many EVs can tow. Expect range to drop sharply, often by half or more, depending on the trailer. Plan charging stops at stations where you can pull through with a trailer.
Is it safe to tow at the maximum rating?
Staying well under the limits gives you a margin for wind, hills and emergencies. Many experienced towers aim for no more than about 80 percent of the rated capacity.
Do I need a special license to tow?
Most drivers can tow light trailers with a regular license. Very heavy combinations may require a special license in some states. Check your state’s rules.
