Difference Between Tandem and Single Axle Trailer

Which is Better? Single Axle Trailers or Tandem Axle Trailers?

The number of axles mounted underneath a trailer determines whether it is a single axle or double axle. A single axle trailer has a one set of wheels; a tandem axle has two sets of wheels. Simple counting can tell you which kind of trailer you’re looking at, which makes it easy to compare trailers and determine which one suits your needs best.

Single Axle Trailers: A single axle trailer is smaller and easier to maneuver than a tandem model; if parking is thin or there is not a lot of wiggle room in your parking area, a single axle model will be easier to handle. The smaller size of a single axle trailer makes it more fuel efficient than its tandem counterparts; towing could be easier due to the lighter weight and adjustable towing angles. Cost is a factor too – not only is a single axle cost less than a tandem axle trailer, tires and maintenance will cost less too. Fewer tires mean less replacement costs. Single axle trailers can have some negatives; their smaller size means that your storage and moving abilities will be more limited. Tires could wear out more quickly if you move a lot of heavy loads, since there are only two tries to absorb the weight.

Tandem Axle Trailers: Like the name implies, a tandem axle trailer has two sets of axles – one right behind the other. The extra tires allow the trailer to carry more weight and to be more stable at high speeds and highway conditions. Bigger payload capacity means more room for whatever you are hauling. Tandem trailers are great for heavier loads and are a great option if you are growing your business. By picking a tandem model, you will be less likely to outgrow your trailer; the extra upfront cost may be worth it in the long run. While towing level is not a factor for single axle models, level towing is a must for a tandem axle trailer. If the load is not level it can cause extra wear and tear on one set of axles and reduce the life of your tires. The initial investment for a tandem trailer is higher than the cost for a single axle model. If you do decide to resell your tandem trailer, you’ll see a much better return on your investment, as they hold their value better than a single axle model.

Single Axle vs. Tandem Axle: Which is Better? The bottom line is it depends. If you are hauling a lot of low weight loads, need maneuverability and to keep your costs down, a single axle model is best. If you are putting some serious highway mileage on your trailer, hauling heavy payloads or are planning to expand your business, a tandem axle model is a better choice.
