What Is The Difference Between Single Axle & Tandem Trailers?

Single Axle vs Tandem Trailers

You know you want to buy a new trailer, but not sure which one? You probably have started your research and now realise there are different types, sizes and models to choose. One of the first questions you might come across is should you invest in a single axle or a tandem?

The construction and axles dictate their performance, so knowing how you will use your trailer will determine which to choose. Put simply a single axle trailer has one axle and one set of wheels, where a tandem has two axles with two sets of wheels. Let’s explore further so you can choose the right one for you.

Single Axle

As mentioned, single axles have one axle and one set of wheels and are therefore lighter and smaller than tandems. If you are solely looking to transport smaller to medium loads, then these are ideal. Mostly purchased for home use, they tow easily behind smaller cars.


  • Smaller and easier to manoeuvre in tight spaces. .
  • Lighter weight so they are easier to tow and more economical on fuel.
  • Generally cheaper to purchase due to smaller size and straight forward construction.
  • Less maintenance needed with only two wheels, tyres, bearings and brakes.


  • Limited by payload. Not suitable to tow heavy loads.
  • More wear and tear on tyres as the weight of the load is distributed over two tyres compared to four.
  • Not required to have a braking system which can present some safety issues.

Tandem Trailers

Tandem trailers are suited to those needing to carry heavier loads and you can easily spot one by its two set of wheels. These models come with two axles close together, along with extra tyres that help disperse the weight of the load. They are perfect for handling heavier loads and offer a higher payload than singles.


  • Most often have better suspension.
  • Generally larger, so you can carry larger loads.
  • Tandems disperse the weight across both axles and set of wheels.
  • More stable at highway speeds and conditions.
  • Safer as the brakes will help you stop, especially important when carrying a heavy load. By law if trailers are rated 750kg to 2000kg it’s a requirement to include brakes.
  • Heavy duty built to regularly transport heavy loads
  • Better stability and sturdiness on the road with less bounce and sway
  • Flat tyres wont completely stop you in your tracks as they are simple to change, even without using a jack.


  • More expensive as they are generally bigger in size and require more complicated construction.
  • Weigh more than single axles, so not as fuel efficient.
  • Increase maintenance with the double axles and 4 wheels and tyres to maintain.
  • Potentially more difficult to manoeuvre in driveways or smaller spaces.

Let’s Get Started

When it comes to choosing between single or tandem, the first step is to work out how you’ll be using it and what you be hauling. If you are towing lighter loads here and there, a single axle is ideal. If you need to carry heavier loads and worry about safety, then a tandem is for you.
