The towing capacity of a semi truck depends upon the number of axles your truck has, and the capabilities and power of the engine.
One reason this is important is that the axle is designed to be able to withstand a certain level of hauling capability. Most large semi trucks are capable of around 40 tons of weight to tow safely.
Here’s a short answer to what Semi Truck can Tow the Most:
The Volvo FH16 semi truck can tow the most. It has an impressive D16G750 engine with 750 horsepower and 2618 lb-ft of torque. The Vovo FH16 semi is capable of hauling loads of over 325 tons, and is generally used for long haul and heavy-duty transport in the construction industry.

What is the Towing Capacity of a Semi Truck?
Towing capacity of a semi truck depends upon the size of your truck and the number of axles it has for hauling the load. The number of axles increases the permitted load for hauling on American highways.
A semi truck with a single axle is permitted to haul 20,000 pounds, 2 axles are permitted 34,000 pounds, and a truck with 3 axles may haul up to 80,000 pounds. Adherence to such regulations is important to prevent damage or accidents.
Each axle has a limited haul weight, and if they are overstrained it can cause damage or injury.
The load may be dislodged or lost if it is too heavy for the truck. Although, this limit varies drastically state by state, and is more of a general statement than a universal one.
Which Semi Trucks can Tow the most?
As stated above the limits to the hauling weight varies between each state, with some states having very little regulation on the weight loads permitted. This means that some trucks exceed the 3-4 axle average.
Most 18 wheeler big rigs have somewhere near 5 axles and are capable of moving 40 tons. These can weigh up to 80,000 lbs. and stretch about 53 feet.
These are the more common models for highway transportation. The specifications regulating trucks vary state by state.
In Michigan 11 axle trucks are common for hauling steel and other heavy metals from site to site and can exceed over 160,000 pounds.
Although in the states of North Dakota and Alaska there are no weight limits to be found.
This means trucks in these states can exceed 11 axles, and well over the average of Michigan’s steel hauling trucks.
These tend to be used by lumberjacks for hauling huge wood loads across the states and to the new desired locations.
How much Weight can a Peterbilt Pull?
Peterbilt engines are preferred for long-distance hauls, due to their strength and efficiency. Peterbilt engines typically have PACCAR engines, which are known for their quality and hauling strength.
Although, the axles on the truck have a relatively large influence on the hauling capabilities as well, with each axle capable of a certain amount of pull. These are important factors to keep in mind when getting your truck.
The Peterbilt 330 can haul up to around 26,000 pounds and has two Dana Spicer axles in the front and back and is a medium-sized truck. Other larger models, such as the 579, can haul up to 70,000 pounds.
How much can a Kenworth Pull?
Kenworth uses PACCAR engines similar to Peterbilt. They are also preferred for their reliability, strength, and ability to haul loads long distances.
The PACCAR engine is a relatively lightweight engine as well which minimizes this from weighing down the load.
Depending upon the model you choose there is a difference in horsepower and torque capability.
The T680 has 355-430 horsepower and has around 1250 – 1550 lb-ft of Torque. Other popular models are the Kenworth T880 which can haul up to 140,000 pounds.
How much Weight can a Freightliner Pull?
Freightliner has the Cascadia engine and is a popular brand, especially in Australia. They are well-liked for hauling heavy loads over the long expanse of the country and have improved their fuel efficiency over the years.
Their engines have horsepower of up to 600. Their torque can get up to 2,050 lb-ft. Their engines range from 13L-16L tanks and have excellent power to haul large loads far distances.
The M2 model only hauls around 1,150 lb-ft with 350 horsepower. These are smaller, almost box car-like design trucks that are great for town and city driving.
The larger models, such as the 3200 Allison Generation series can haul up to 30,000 lbs. with efficiency.
How much can a Volvo Tow?
Volvo trucks have a number of models with different specifications for handling different loads and terrain.
To name a couple of their more popular models, there are the VNL, VNR, and VNX lines each with different abilities.
These trucks can haul up to 2,050 lb-ft with a 605 horsepower engine. Volvo engines aren’t the most powerful on the market, but most models are good for town/city driving and can maneuver more easily in close quarters.
One of the most impressive, newer models of Volvo which we mentioned above is the F16.
This incredible truck surpasses most trucks of similar size with its hauling capabilities. This truck can haul up to 325 tons of load, which surpasses the average load limitations of 40 tons.
How much Weight can a Tesla Semi Truck Pull?
The Tesla truck, also known as the Cybertruck, has surprisingly high levels of torque.
The engines are not fuel-based, and have been modified to utilize a mixture of power sources including solar power.
Although still mainly in the testing stage, many project the model can tow 14,000 lbs. easily. Some estimate that the Tesla 8 class will be capable of towing up to 80,000 lbs.
This will put it up to scale with the highest level of hauling capabilities of the average large semi truck.
Additionally, the Tesla engine is capable of handling inclines with remarkable ease and to run efficiently.
One of the worst parts of travel with a semi truck is the potential incline which can change your fuel usage from 7 mpg to 2 mpg. This issue is substantially lessened by the Tesla truck.
How much Weight can a Single Axle Semi Truck Pull?
There is a legal limit to the amount of weight each axle on a semi truck is permitted to haul. This is the cause for those checkpoints and weighing stations which check to ensure they meet specifications.
The legal limit for a single axle truck is 20,000 lbs. This is considered the average weight for a small semi truck.
The limits are in place to ensure safe travel as well as ensure the load does not break the axle under the weight.
The following article on maximum legal vehicle weight limits is helpful in determining the proper weight per truck design and number of axles.
Can a Semi Truck Tow another Semi?
Yes however, semi trucks are not specifically designed to tow other semi trucks. The kingpin must match the model you wish to two in order to prevent it from possibly being damaged or damaging your truck while it pulls the load.
You need proper chains to haul safely, and be sure that you have the flashers on while you haul the load. In order to ensure you operate safely and legally be sure you don’t exceed the legal weight permitted for your own truck.
The following link has an excellent guide to help you ensure you operate safely.
How much Weight can a Semi Truck Legally Carry?
There are federal and state laws regarding the limits to the weight permitted for each kind of truck. These limits vary based upon the number of axles and the number of axles.
Generally, semi trucks are permitted to haul up to 80,000 pounds interstate. This can vary per state, and there are special permits that are granted in order to haul extra-large loads.
These trucks usually have “oversized load” posted on the front and back and are only allowed on certain routes.
Some states choose not to abide by these regulations and permit very large loads with little restriction, or no limits at all.
Although, be sure to check any interstate regulations which may be applicable for your load prior to leaving.
