Tandem Axle Vs. Single Axle

Save

Wheels revolve around pins called axles. A single axle holds two wheels together; a tandem axle holds two sets of wheels closely together. Unless your trailer or caravan is more than 17 feet long, axle choice is a matter of preference.

Single Axle Advantages and Disadvantages

  • Single axles maneuver more easily and weigh less than tandem axles. Since single axles must carry less weight than a tandem axle, singles make for better fuel economy and less towing wear-and-tear.

Tandem Axle Advantages and Disadvantages

  • Tandems have more stability and straighter tows than single axles, which tend to sway without a sway control device. Four tires limit the tandem's turning radius and cost more to replace than single axles.

Final Tidbits

  • Tandem axles cost more than singles as they support twice as many tires. When choosing one type over the other, keep in mind that your suspension should be in tip-top shape as it affects your tow ride.
