How Much Can My Truck Tow?

Introduction

Towing is the act of pulling a load or another vehicle using a hitch or tow bar attached to the primary truck. For example, when a truck pulls a trailer carrying furniture from its warehouse to a retail outlet, it is towing. It is utilised across various industries.

Tow trucks are specialised trucks for towing purposes. These trucks are designed with the structure and power necessary to pull a load in addition to their weight. This blog provides a simple guide to towing capacity, helping you understand your truck’s towing capabilities.

What Is the Truck's Towing Capacity?

A truck’s towing capacity is the maximum weight it can safely pull. More specifically, it is the total weight of the trailer and its contents that a truck can safely pull for its operations.

(Note: A trailer is an unpowered vehicle that is towed by a truck or another vehicle to transport goods or cargo.)

A truck’s towing capacity is determined by its manufacturers by considering various aspects of the vehicle’s and trailer’s weight. It is expressed as a rating for better understanding.

Why Is It Important to Know the Truck's Towing Capacity?

1. Safety:

   Towing involves risks that affect both - people’s safety and financial investments. Thus, it’s important to prioritise safety when towing. Being aware of and adhering to the truck’s maximum towing capacity helps achieve this. It prevents overloading, ensuring the safety of the operational staff and preserving the items being towed.

2. Performance:

   Given the substantial investment involved in towing, it is paramount to get optimal results. Following the maximum towing capacity helps ensure this. It allows you to plan the type of cargo you can tow and estimate the number of towing trips needed. This will enhance operational efficiency, leading to improved performance and increased profitability.

3. Damage prevention:

   Purchasing a towing vehicle is a significant investment, and as noted, the items being towed are also valuable. Damage to the vehicle or cargo may lead to considerable financial liabilities and disrupt operations. Staying within the towing capacity helps prevent damage. This is because it ensures the truck doesn’t carry more than it can handle.

4. Regulatory compliance:

   Towing rules and regulations are formulated by nearly every country's government and industry authorities. You must adhere to these rules and regulations throughout your operations. One of the rules is adhering to the truck's towing capacity. Therefore, be aware of and adhere to it, as its violation can result in penalties and punishment.

What Are the Various Aspects of The Truck's Towing Capacity?

• GVWR:

  GVWR stands for Gross Vehicular Weight Rating. It is the maximum weight that the vehicle can carry. Due to the nature of the rating, there are two separate GVWRs: one for the tow truck and one for the trailer.

• GCWR:

  GCWR stands for Gross Combined Weight Rating or Gross Combined Weight Ratio. It is the maximum weight of the vehicle and its trailer or any other items attached to it. You should never exceed the specified limit, as it can jeopardise the vehicle, your staff, and the cargo.

• GAWR:

  GAWR stands for Gross Axle Weight Rating or Gross Axle Weight Ratio. It is the maximum weight that the truck’s axles can carry. It is classified into two ratings: Front axle rating and rear axle rating. (Note: An axle is a central shaft that connects two wheels, allowing them to rotate together.)

• Dry weight:

  It is the weight of the truck, including its structure, components, passengers on-board, and cargo. It does not include the weight of the fluid’s prerequisite for truck operations, such as fuel and engine oil.

• Curb weight:

  It is quite similar to dry weight as it includes the trucks’ structure, components, passengers, and cargo weight. What differentiates it is that it includes the weight of the fluids used in the truck's operation.

• Tongue weight:

  It is the measure of the downward force that the trailer exerts on the truck’s hitch. It accounts for approximately 10-15% of the trailer’s total weight. Its adherence plays a crucial role in maintaining towing stability.

How Much Can My Truck Tow? How To Improve Its Towing Capabilities?

You can know your truck’s towing capacity by referring to the owner’s manual provided by the dealership at the time of purchase. You can also find this information by conducting a simple online search with your truck’s model, make, year of purchase, and the term "towing capacity."

Way to improve a truck’s towing capabilities:

• Use a high-quality hitch to attach the trailer to the towing truck. It will help ensure security and stability. You can also use a weight-distributor hitch. It helps evenly distribute the trailer's weight when attached to the truck, ensuring safety and operational efficiency.
• Suspensions are systems that absorb shocks and support a vehicle's weight for a smoother ride. Upgrading to parabolic spring suspensions can enhance the vehicle’s support, allowing it to tow heavy cargo without compromising performance.
• Tires are another factor in enhancing your truck's towing capabilities. Ensure all tyres are properly aligned and adequately inflated. This will ensure the tyres effectively support the truck during towing activities while maintaining stability throughout operations.

What is the difference between a truck’s towing capacity and payload capacity?

As mentioned, towing capacity refers to the maximum amount of weight a truck can safely pull. Generally, a trailer loaded with cargo is attached to the truck and pulled. This means the focus is on the truck's capacity and the trailer’s weight.

On the other hand, payload capacity is the maximum amount of weight the truck can carry itself. In simple terms, what is the maximum weight that can be loaded onto the truck’s bed or cargo container? This means the focus is on the truck itself.

Summing It Up

Towing capacity refers to the maximum weight a truck can safely pull when attached to a trailer. It is determined by the vehicle’s manufacturer and expressed as a rating. Knowing and adhering to your truck’s maximum towing capacity is crucial, as it significantly impacts both operational safety and performance. It is also important from a regulatory compliance perspective.
