With a single axle trailer, they would be allowed a gross weight of 52,000 lbs for interstate use. Pulling a set of doubles, they're still limited to 80,000 lbs. gross weight by the federal regs, but some states will allow them 92,000 lbs. gross weight for intrastate use.

The weight limit of a single axle trailer depends on several factors. The frame, axle type, tire rating, and the springs all have to be factored in.Smaller trailers could be rated at only a few hundred pounds, while heavier built units can haul full sized cars.
Well, that depends on what it's pulling. The federal law allows a max weight of 80,000 lbs., including for double trailers. Some states will allow a truck pulling doubles to gross 92,000 within that state. They can haul as much weight legally as a tandem axle tractor-trailer can, so long as they remain within legal axle weights.
There are several different axle and wheel sizes that each carry different loads.
20,000 on the steer axle, 34,000 on the drive tandems together.
What it says on the side is irrelevant. Permissible Gross Vehicle Weight is determined in accordance with the Bridge Law Formula. 50k was probably the normal GCWR with the trailer it normally pulls - most likely, also a single axle, although 52k should be the correct GCWR for a single axle with a 27' single axle pup trailer, though a 20k gooseneck trailer is also possible. There may also be a possibility that was the weight it was licensed for - this is something which also varies by state.
12000 pounds
About 16,000 - 18,000 for a regular line haul unit, depending on specifics.
That depends on the axle configuration. If it a closed tandem typically 17,000. If it is a spread axle 20,000. If it is a single axle (Front of a Semi) typically 12,000. Those would be the "legal weights", but states allow different amounts of weights with a permit for over weight. That all depends on the state. Wisconsin will allow 23,000 per axle.
It can vary according to the configuration of the trailer axles. A straightforward tanndem, with no spread, is permitted 34.000 lbs. on the trailer axles, which would allow the combination to gross out at 66,000 lbs. A 10 ft. spread axle, on the other hand, is allowed to weigh 40,000 on the trailer axles, which would permit the combination to gross 72,000 lbs.
There are several factors taken in to account to determine the weight load limit on any number of axles in South Dakota. These factors include the number and spacing of a vehicle's axles and the size of its tires. There may also be Spring Load Limitsin force.The maximum allowable weight for all individual axles and axle groups is limited by statute: single axles is 20,000 pounds, tandem axles is 34,000 pounds, and other axle groups are determined by the Bridge Weight Formula.
