Tandem vs. Single Axle Trailers: What’s the Difference?

Blog Article

When choosing a trailer, one of the first decisions is whether you need a single axle or a tandem axle. This affects everything from weight capacity to towing stability, and even how much maintenance you’ll deal with.

In this guide, we compare tandem vs single axle trailers — so you can choose the right setup for your hauling needs.

1. What Is a Single Axle Trailer?


A single axle trailer has one set of wheels, typically used for:

  • Light-duty hauling

  • Smaller trailer sizes (5×8, 6×12)

  • Lower towing weight


✅ Pros:

  • Lower upfront cost

  • Easier to maneuver in tight spaces

  • Lighter = better fuel economy

  • Less maintenance (1 axle = 2 tires)


❌ Cons:

  • Limited payload capacity

  • Less stable at high speeds

  • No built-in brake redundancy


2. What Is a Tandem Axle Trailer?


A tandem axle trailer has two axles (4 wheels total), making it better for:

  • Heavier loads

  • Long-distance towing

  • Larger trailers (7×16, 8.5×20, etc.)


✅ Pros:

  • Handles more weight

  • Better stability on highways

  • Smoother ride

  • Safer if one tire blows


❌ Cons:

  • Higher cost

  • Slightly harder to turn and park

  • More tires and parts to maintain


3. When Should You Choose Single Axle?


Go with a single axle trailer if:

  • You haul under 3,000 lbs regularly

  • You’re using a smaller vehicle or SUV

  • Your trailer will be stored or parked often

  • You’re prioritizing budget over cargo size


???? Best for: Utility trailers, small enclosed trailers, occasional use

4. When Is Tandem Axle the Right Choice?


Choose a tandem axle trailer if:

  • You carry heavy equipment, materials, or tools

  • You travel longer distances or drive at highway speeds

  • You want extra stability and safety

  • You need a trailer with brakes on both axles (often required by law)


???? Best for: Dump trailers, food trailers, horse trailers, car haulers

5. Legal and Safety Considerations


Depending on your state:

  • Trailers over 3,000 lbs may require brakes on all axles

  • You may need a tandem axle setup for commercial applications

  • Tandem axles are often safer in poor road conditions


???? Equilhaul can guide you based on your location and vehicle.
