Gross Vehicle Weight Rating
Gross Vehicle Weight Rating is the maximum amount of weight your vehicle can support while sitting still. It is affected by your cars frame, wheels, suspension, and axles. A change to any one of those will change the GVWR.
The GVWR is usually found on a sticker inside the drivers door jamb and in the owners manual.
Likewise, a tow vehicle and the trailer it is pulling each have a unique GVWR. What is important is that you dont overload either.
GVWR is not towing capacity. To clarify, the amount of weight your vehicle can support that pushes down on it, and the amount of weight it can pull behind are two different numbers. For instance, its like how the weight you carry on your shoulders is not the same as the amount you can pull in a wagon.
Exceeding Towing Capacity: Shortened Life For You And Your Car
Just because your pickup might be able to manage the extra weight of the boat for a quick trip doesn’t mean it’s OK to do. Your ailing grandmother could probably carry a heavy backpack across the room too, but would you really ask her to do it?
Just like repeated trips across the room with a bulging bag would put a strain on Nana’s back and likely lead to broken bones, a few trips to the mountains with that four-wheeler will put a similar break in the life of your truck. Vehicles are designed to handle only a certain amount of force, and the way they’re constructed reflects that. That’s why commercial trucks that regularly haul tons of cargo across the country have significantly bigger wheels, more powerful engines and stronger braking and suspension systems than do passenger cars.
When you ask your truck to pull more than it was meant to — exceeding its towing capacity — a number of things start to happen: The brakes begin to fade, the added weight contributes to tire failure, and the extra work required of your engine causes it to overheat, which, in turn, overloads the drivetrain and shortens the life of your transmission.
Although you may not see the effects of exceeding towing capacity at first, the gradual wear and tear will lead to eventual failure. The best case scenario is repeated trips to the repair shop the worst is a major wreck.

Online Charts Are Not Reliable
Some website post online charts of vehicle towing capacities. While these charts can be useful if you’re buying a new vehicle, they are probably the least reliable source of information about your vehicle’s overall towing capacity. Most experts do not recommend using online charts to find out how much your car can tow.

Maximum Trailer Payload Considerations
The difference between the dry weight and the gross weight is the trailers payload. If the trailer has a payload of 2,000 pounds, thats how much stuff you can pack into it.
Remember the heaviest thing in your trailer is water. If you travel with water in your fresh water tank, grey and black tanks, consider water weighs 8 pounds per gallon. It can also have the unique property of being a live load while going down the road.
What To Keep In Mind When Towing With Your Vehicle
On paper towing with vehicles seems to be simple. It really inst that complicated, but there are a few things to keep in mind when you are getting ready to tow with your vehicle in regards to how much your vehicle can handle.
Vehicles Listed Max Towing Capacity

In fact, you should avoid towing loads that fall anywhere close to the vehicles maximum abilities because it could end up being more than it can handle, especially if you are driving through the mountains or other rough terrains.
Towing weight that it over or too close to a vehicles maximum towing capacity causes problems to the car and also be very dangerous to the driver and other passengers if something did happen to go wrong. It is best to keep it safe and not push the limits.
It is beneficial knowing what your vehicles limit is to know how much it can, cant, or shouldnt handle, and for that reason the numbers that i have listed above are all the different types of vehicles maximum capabilities for towing.
Other Weights to Keep in Mind When Towing

Learn The Weight Of The Trailer
Trailer dealers can easily mislead you in the allowed weight a trailer can handle. This is because trailers use both GVWR and what is known as either dry weight, unloaded vehicle weight or dry hitch weight. Dry weight refers to the weight of the trailer when empty and does not include any extra equipment you may load such as batteries or tanks. Ignore this number and find the GVWR of your prospective trailer. Ask for assistance if you cannot locate the number on the trailer.
Note that the hitch on your towing vehicle will only tow the weight transmitted through the tongue of the trailer. To calculate the maximum tongue weight of the trailer, multiply the trailers GVWR by 15%. That is,
GVWR x 0.15 = TW
Other Towing Tips For A Safe Ride
First, check with your states laws concerning towing. AAAs list will help guide you in finding out what laws you may need to adhere to. Many states have relatively lenient regulations, while others have special requirements. Be sure to consult the laws in your state and any state you plan on traveling to with your trailer.
Always take your time when preparing a trailer and its load. Double and triple check to be sure all items are secure and you have the trailer connected properly. This will help you avoid any accidents that could occur if something was done incorrectly.
Knowing and following your towing capacity will help keep your vehicle and your passengers safe. Dont exceed the recommended rating for your towing truck or car just for the sake of saving money or time. Your life, as well as others, could be at risk.

Towing A Combined Weight Over 3500kg
If you wish to tow a trailer over 750kg which would result in a combined weight of over 3,500kg, you will require a B+E entitlement on your driving license.
The date on which you passed your driving test also has some baring on the amount of total weight you are able to tow without needing a B+E entitlement on your license. Drivers who passed their driving test after 1st January 1997 and only have a standard category B driving license can:
- Drive a vehicle up to a maximum weight of 3,500kg while towing a trailer of up to 750kg
- Tow a trailer heavier than 750kg, providing the combined weight of the trailer and the towing vehicle is not over 3,500kg
For anything heavier you will need to take a category B+E driving test.
However, drivers who passed their driving test before 1st January 1997 are generally allowed to drive a vehicle and trailer with a combined weight of up to 8.25 tonnes.
How To Figure Out Towing Capacity
The short answer is that you want to make sure the weight of the trailer and its load doesnt exceed the gross vehicle weight rating of your truck, car, or SUV. In standard situations, if your vehicles GVWR is 10,000 lbs and you only plan to haul 1,000 lbs of cargo, youre good to go. But thats not always the case.
A post shared by GMC on May 5, 2019 at 9:47am PDT
If you feel you might be close, you will need to dig a bit deeper. Lets say you have a truck thats rated for 12,000 lbs. If you want to haul a camper trailer thats 10,000 lbs, you could potentially exceed the rated towing capacity of your vehicle. You must determine what your actual combined weight is with towing vehicle, passengers, cargo, and camper. Then youll need a calculation of all the items you plan to put into the camper, like bedding, linen, food, and water. Those items might put you over.

How Do I Work Out My Cars Towing Capacity
Towing capacity is the maximum weight a car can tow legally. However, it may not be safe or comfortable to do so, especially with a caravan or trailer that has a large box-like profile.
The towing capacity may be published within the handbook of the vehicle. It can also be calculated from the VIN plate, where line one is the maximum allowable mass and line two is the maximum trian mass. Simply deduct line one from line two and you have the vehicle towing limit.
For safe towing it is recommended by many towing experts that a novice should keep the fully laden weight of the caravan no heavier than 85% of the kerbweight of the tow car. This is known as the 85% rule. Bear in mind that it is a guide and not legally enforceable.
To calculate this, you only need to know two key figures: the kerbweight of the car and the maximum mass of the caravan .
If the mass of the caravan is 85% or less of the cars kerbweight, the car will tow it with ease.
If its between 85% and 100%, be careful only experienced caravanners should use that car to tow such a heavy van.
But if the caravan is heavier than the car, then it is strongly recommended not to use it to tow that caravan. This calculation is known by experts as outfit matching.

Check Your Cars Towing Capacity
If you are towing a trailer or caravan it is really important that you take extra care as there are a lot of additional factors you need to take into account.
When towing a trailer you should always think Safety first!!
In general, car and van accidents that involve a trailer have far greater consequences than those where no trailer is involved. The main reason for this is the additional size and weight that the trailer adds to your vehicle along with the fact it is only attached by a very small point.
Making sure that the trailer you are planning on pulling is within the towing capacity of you car is extremely important. Whilst the 85% Rule is there as a guide, its important to know that the towing capacity and weight vary from car to car and between different models so please make sure you find the exact towing capacity for your car and that you double check this in your cars handbook.
