Tandem Axle vs Single Axle Trailer: Which is Better for Your Cargo Transportation?

When it comes to purchasing a trailer, selecting between a tandem axle and a single axle is a crucial decision that can greatly impact your towing experience. Yes, costs, weight capacities, safety, applications, and many other aspects differ. But you can choose one over the other based only on your requirements.

The trailer you choose for your transportation needs affects your towing efficiency, safety, and budget. The more axles there are, the better the weight distribution, but the costs also rise. So, you must be highly cautious when contemplating a tandem axle vs. single axle trailer.

This blog explains these two trailers in detail, with their merits, demerits, and best applications. We also help you compare both on different aspects and choose the right one for your needs.

What is a Single Axle Trailer?

A single-axle trailer has one axle, with a wheel mounted on each end, so it has two wheels. The axle has wheel bearings, leading to wheel rotations, while the single axle makes the trailer capable enough to support the cargo weight. The width of such trailers ranges from 4 to 7 feet, and the length range is 8 to 14 feet, with a maximum weight capacity of between 2,900 and 3,500 pounds, trailer weight included, and depending on whether you opt to add electric brakes. You can, of course, add capacity by upgrading to a 5.2K axle. You can have them as open or enclosed trailers, depending on your cargo. You can use any towing vehicle (cars, vans, SUVs, etc.) to attach these single-axle trailers and transport cargo.

Pros

Since they are light in weight and small in size, towing them is easier, faster, and smoother.
The lightness of the trailer also gives you more fuel efficiency and faster braking.
The purchase price is affordable, plus the maintenance expenses are less because you need fewer tires and suspension parts.
A simple construction and fewer components allow better maneuverability in tight spaces and sharp corners.
Fewer components mean lesser wear and tear, reducing the need and frequency to maintain, repair, and replace.

Cons

The single-axle design prevents you from carrying heavy weight on the trailer.
You will feel the difference in stability when riding on rougher terrains or bumpy roads; it sways more than a tandem axle trailer.
Even at high speeds or in windy conditions, the trailer wavers more, making it less stable.
Some single-axle trailers have no brakes other than the ones in vehicle, so safety can be an issue.
Single axle trailers are not as forgiving where stability is concerned in the event of a tire blowout.

Uses

You can use these trailers for short-distance transportation of lightweight and small-sized goods. These can include building supplies, furniture, motorcycles, boats, tractors, landscaping materials, lawn care equipment, and other small cargo, which can be handled well by the single axle.

A precaution to take when using single-axle trailers is to avoid overloading them with heavy cargo because that can lead to tire blowouts, hitch issues, or vehicle damage.

What is a Tandem (Dual) Axle Trailer?

A tandem (dual) axle trailer has two axles and four wheels. The two axles are close and have a wheel at each end, facilitating better weight distribution. Their length range is between 12 and 26 feet, their width ranges between 6 and 8.5 feet, and their weight capacities start at 7,000 pounds and go up from there depending on your axle upgrades.

Pros

With a better weight distribution due to two axles and four wheels, these trailers can carry heavy cargo or multiple items simultaneously.
The enhanced weight distribution ensures the trailer does not sway or waver during transportation, making it stable and safe.
Trailers with multiple axles have braking systems - electric and hydraulic. Hydraulic brakes are in the trailer but respond to the towing vehicle, while electric brakes run on power from the vehicle's electrical system. These enable safe and smooth towing.
Due to their stability, dual-axle trailers have a lower risk of swaying in windy conditions, on rocky terrains, or at high speeds.
With four tires, you do not have to worry when one goes flat; the other three can assist the ride until you pull over at a safe place to change.

Cons

Tandem axle trailers are more expensive, and maintenance is also higher-priced due to the requirement to have extra tires and suspension components.
Since the weight capacity is high, you need a strong towing vehicle, like a truck, to tow the trailer.
The heavy weight capacity and big size also contribute to higher fuel usage and lower fuel efficiency.
The toll charges are also higher for a vehicle with more axles and heavy weight, costing you more.

Uses

Double-axle trailers' stability on the roads makes them suitable for frequent long-distance transportation requirements. You can tow heavy cargo, including construction materials, farming gear, cars, generators, industrial machinery, several vehicles, trucks, and tractors.

How to Choose the Right Trailer for Your Needs

When you are confused about choosing a tandem axle vs a single axle trailer, you must consider the factors described below:

Assess Your Cargo Needs

Identify your cargo as a whole. Determine its weight and dimensions - height, width, and length. You must also consider the towing vehicle you will use for transportation and the frequency of such transit operations.

Consider Road Conditions

It is also critical to consider the conditions of the road you will be traveling on during these transits. Check if the roads are smooth, silk-like or rough and rocky, whether they are highways or inter-city roads. This aspect is essential because single-axle trailers run better on smooth and city roads, while tandem axle trailers are best for highways and rough terrain.

Budget Matters

Your budget for purchasing a trailer is a crucial aspect to consider, along with the usage of the trailer. If you are looking for a cheaper and short-term usage option, then the single axle trailer is suitable. In the case of high-frequency trips for many years, investing in tandem-axle trailers is better, even if it is expensive. These trailers are durable and have higher ROI.

Legal & Safety Considerations

An often-ignored aspect is legal and safety considerations. Before buying the trailer, refer to the laws in the U.S. and your state. In some states, the weight categories and road types for single-axle trailers differ. This aspect also affects the safety of the vehicle, driver, and cargo.

Conclusion: Which Trailer Is Right for You?

Money matters. Successful cargo transportation is your ultimate goal. So, you must be cautious about the type of trailer you buy. A single-axle trailer is a great choice if you desire affordability, easy towing, and fuel efficiency for light loads. But go for a tandem axle trailer if you want stability, durability, safety, and higher weight capacity.

Before choosing a trailer, understand the differences between tandem axle and single axle trailers. Invest money only after considering the factors, including hauling needs, road conditions, budget, laws, and travel distance.
