Trailer Axles: The Pros and Cons of Single vs. Tandem Trailers

Are you constantly moving heavy loads from one location to another? You could benefit from owning a trailer. But as you browse the web for the perfect types, you might notice two variations: a single-axle box trailer and a tandem axle box trailer. What is the difference between these two, and which is the best among custom trailers?

How a Single Axle Differs from a Tandem Axle Trailer

You only need to remember one characteristic when determining which is which. Single axle trailers have one axle and two tyres, while tandem axle trailers have two axles placed close to one another and two sets of tyres.

Each of these trailers offers distinct benefits for specific purposes. If you are unsure which one to get, we compiled a list of the pros and cons of single-axle and tandem axle trailers.

Single Axle Trailer

The Pros

  • Easier Maintenance – since single-axle trailers have one axle and a pair of tyres, the brakes and bearings are easier to maintain or replace.
  • Economical – single axle trailers are relatively lighter compared to dual axles, making them more efficient and economical to tow.
  • Manoeuvrability – the lighter structure of single axles makes them effortless to manoeuvre than heavier axle tandem trailers.

The Cons

  • Can’t Haul Heavier Loads – single axle trailers can’t carry as much as tandem axles can. 
  • Wobble – if you get a flat tyre in the middle of your travel, the trailer might be unable to support the weight and wobble as you drive.
  • Tyres could Wear – because only one set of tyres supports the bulk of your load, they could accumulate damage as they absorb the weight.
  • No cushioning – if the single axle trailer has no suspension, it may not cushion the cargo or provide stability on rough terrain.

Tandem Axle Trailer

The Pros

  • Long Distance – tandem axle trailers are better suited for long-distance travel drivers.
  • Higher Weight Capacity – most tandem axle trailers can carry 750-3000kg, depending on the unit.
  • Stability – because they come with better suspensions and two sets of tyres, tandem axle trailers are less susceptible to swaying during journeys.
  • Easy Tyre Fix – a flat tyre becomes less of an issue since it can easily be replaced without a jack

The Cons

  • Costs More – the initial purchase, maintenance, and repair expenses of tandem axle trailers are higher than single axle variations due to more parts and better materials.
  • Difficult to Manoeuvre – depending on how heavy the load is and the brand of the trailer, tandem axles may be more difficult to control.
  • Lower Fuel Economy – the heavier weight of tandem axle trailers increases fuel consumption as the car works twice as hard to tow your cargo.

Due to its capacity and sturdiness, business owners can reap many benefits from tandem axle trailers. While single axles are more affordable and easier to control, double axles offer more in the long run in terms of practicality. Australia’s Trailers 2000 provides a selection of high-quality tandem axle trailers for various uses ranging from off-road to equipment transport.
