How Much Weight Can A Tow Strap Pull?

By: Dawnerz


Time to read 4 min

When people ask "How Much Weight Can a Tow Strap Pull?" it’s kind of like asking how long is a piece of string! It's not a simple one-option answer!

The amount of weight that a tow strap can pull varies on a wide variety of factors, from materials, stitching techniques, type of material used in the stitching, the width of the webbing, the tensile strength, the number of layers of webbing, and the overall quality of all of these combined.

So let's try to break it down to fully enable you to understand this commonly asked question.

Tow Strap - Tensile Strength Of The Webbing

The most common material used in towing straps is polyester. While many are familiar with the key features of polyester, it's essential to note that different grades exist, each with varying tensile strengths.

For instance, consider three tow straps, all featuring a 6-inch width of single-ply webbing:

Tow Strap 1: Webbing with a Tensile Strength (TS) of 2000 lb per inch

Tow Strap 2: Webbing with a TS of 4000 lb per inch

Tow Strap 3: Webbing with a TS of 6000 lb per inch

Despite their visual similarities, these straps exhibit significant differences in their Minimum Break Strength (MBS):

Tow Strap 1: 2000 lb x 6 inch = Minimum Break Strength of 12,000 lbs

Tow Strap 2: 4000 lb x 6 inch = Minimum Break Strength of 24,000 lbs

Tow Strap 3: 6000 lb x 6 inch = Minimum Break Strength of 36,000 lbs

Adding a second ply of webbing to these straps doubles their Minimum Break Strength

Tow Strap 1: Double Ply gives a Minimum Break Strength of  24,000 lbs

Tow Strap 2: Double Ply gives a Minimum Break Strength of 48,000 lbs

Tow Strap 3: Double Ply gives a Minimum Break Strength of 72,000 lbs

Each additional layer of webbing further multiplies the tensile strength, enhancing the overall towing capacity and durability of the tow straps.

Importance of Webbing Width in Tow Straps

The width of the webbing in tow straps plays a crucial role in determining their strength and towing capacity. Building upon the information provided earlier, let's consider a webbing material with a Tensile Strength (TS) of 4000 lb per inch.

A manufacturer could utilize this material to create tow straps of varying widths, such as 6 inches, 8 inches, and 12 inches.

Despite using the same material with a consistent TS, each increase in width adds 4000 lb of break strength to the tow strap. This means that a wider tow strap inherently possesses a higher Maximum Break Strength (MBS), enhancing its ability to withstand greater forces during towing operations.

Therefore, the width of the webbing is a critical factor to consider when evaluating the overall strength and performance of tow straps.

Lets take our 200,000 lb MBS heavy duty towing strap as an example.

The Dawnerz 20 ft tow strap and 30 ft tow strap boasts an impressive 200,000 lbs breaking strength.

This specific heavy duty towing strap boasts a remarkable capacity of 200,000 lbs and features a width of 11.8 inches with two layers of webbing.

The width of the strap, in this case, being 11.8 inches, significantly contributes to its overall strength and load-bearing capacity. A wider strap distributes the force more evenly across its surface area, reducing stress concentration points and enhancing the strap's ability to withstand heavy loads.

Type of Stitching

The choice of stitching plays a crucial role in determining the overall strength and durability of towing straps. Even when using high-grade webbing, the quality of the stitching material can significantly impact the Maximum Break Strength (MBS) of the straps. Opting for mediocre or low-quality stitching materials may compromise the integrity of the straps, reducing their load-bearing capacity.

Moreover, the type of stitching pattern employed contributes to the strength or weakness of the straps. Smaller, more condensed stitching patterns provide a compact stitch per square inch, reinforcing the overall strength of the straps. These patterns create a tighter bond between the webbing layers, enhancing the strap's ability to withstand heavy loads and stresses during towing operations.

Therefore, selecting high-quality stitching materials and utilizing appropriate stitching patterns are essential factors in ensuring the reliability and performance.

How Much Weight Can A Tow Strap Pull?

So to answer the question, How Much Weight Can a Tow Strap Pull? The weight capacity of a strap depends on its design and intended use. Tow straps for cars typically range from 3000 to 5000 lbs. In contrast, our Heavy Duty Tow Straps boast an impressive break strength of up to 380,000 lbs, making them suitable for heavy-duty towing tasks.

To summarize, the strength and performance of tow straps are influenced by a combination of factors such as material quality, webbing width, number of layers, stitching type, and overall construction.

Choosing high-grade materials, appropriate widths, and stitching patterns can significantly enhance a tow strap's Maximum Break Strength (MBS) and durability.
