Difference Between a Tandem and Dually Axle

Published 04/09/2014

Question:

I have a 16,foot 2 axle 4 wheel trailer. I am not sure of the terminology of duel. What would the torque be. I consider a duel as two wheels on each hub is that correct? Thanks

It sounds like you have a tandem axle, which means you have a total of two axles on your trailer. A dually axle or dual wheel axle would be one where there are 4 wheels on a single axle. So if you had a tandem dually axle you would have a total of 2 axles and 8 wheels.

Typically torque specs for trailer rims is between 50 and 75 ft lbs of torque.

I attached an FAQ on trailer tires that you might find interesting also.
