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.
What is the dot weight limit?
General Rule. 35550. (a) The gross weight on any one axle shall not exceed 20,000 pounds, and the gross weight upon any one wheel, or wheels, supporting one end of an axle, shall not exceed 10,500 pounds.
How do you shift the weight off of a drive axle?
To shift weight off the drive axles and onto the trailer tandems, you slide the trailer tandems forward toward the front of the truck. With 6 inch spacing you’re moving 400 pounds per hole so you need to move 4 holes to shift a minimum of 1,400 pounds (400 x 4 = 1,600).
How much weight can a 3500 single axle carry?
For example, if a single-axle trailer has a 3,500-pound GAWR, this means the trailer can carry no more than 3,500 pounds, including the weight of the boat and trailer, engine, and fuel. If a double-axle trailer has a pair of 3,500-pound axles, its GAWR is 7,000 pounds. Axles are available in many weight capacities.
How do I know how much weight my trailer can hold?
Subtract the empty weight of your trailer from the GVWR listed. The resulting number will be the maximum available cargo capacity of the trailer. Do not exceed this number. In addition to knowing your trailer’s towing limit, you need to know how to determine the correct load limit for your tow vehicle.
How is Gcvwr calculated?
Start with the maximum total weight your truck can handle, known as its Gross Vehicle Weight Rating (GVWR). GVWR is also determined by the manufacturer and is listed in your owner’s manual. Subtract your truck’s curb weight from its GVWR—that’s your payload capacity!
