How do I know what axle weight to use?

How to Calculate Axle Weight

  1. Add the total weight of the load you will be carrying to the total trailer weight.
  2. Divide the total weight of the load and trailer by the total number of tandem axles. Include the load bearing axle in your count.
  3. Write down the total weight of your tractor or pickup.

How do I know my axle load?

Simply subtract the kerb weight of each axle from the maximum legal axle weight figure on the plate. The difference between the two figures is the maximum load that can be carried on each axle.

What is the dot weight limit?

Federal law controls maximum gross vehicle weights and axle loads on the Interstate System. Federal limits are 80,000 pounds gross vehicle weight, 20,000 pounds on a single axle, and 34,000 pounds on a tandem axle group. There are also Federal standards for length and width on the National Network (NN).

What is the difference between set forward and set back axle?

Registered. the set back will give you a better steering diameter, but lessen the ability to load the rear more. the set forward will allow you to stack more weight on the rear axles because there is more balast (sp) out front…

What is another term often used for axle setback?

the difference in distance between any axle end and the perpendicular centerline. Also called axle setback or setback.

How much weight can 2 7000 lb axle carry?

14,000 lbs
So, if you had two axles rated for 7,000 lbs then your trailer’s GVWR will be rated at 14,000 lbs.

What kind of tires do you need for a steer axle?

Certain heavy haulers need wide-aspect front tires not only to handle the load, but also to meet some state’s tire-width requirements. “The rule is typically 600 psi of tire width, but it can be as low as 500 psi width,” says Dean. “Mounting 425/65R22.5 tires on the front will be good for up to 22,000 lbs. on the steer axle in most states.

How much weight can you put on a common axle?

Examples of GAWR on common axles. In the EU and U.S. legal maximum load restrictions are placed on weight, independent of manufacturer’s rating. In the EU a tractor can generally have 10 tonnes (22,000 lb) on a single axle, with suspension type and number of tires often allowing slightly higher loads.

Which is the maximum load for each axle?

No matter what local regulations drive your truck configurations, you must adhere to a few basic guidelines. The Gross Axle Weight Rating (GAWR) determines the maximum load for each individual axle, and the GVWR must not exceed the capacity of the individual axle ratings.

Which is better front axle or back axle?

However, if local regulations allow, an axle-back configuration offers several key benefits. “If you are free to use the axle back, the advantages over the axle forward are reduced turning radius because of the axle position, and you are also going to have greater payload transfer to the front axle,” says Ginter.
