Is Bow in 3,500 lb Trailer Axle Enough Camber for Loaded and Unloaded Trailers

Question:

I have been researching your trailer axles. Im assuming that the manufacturer fits the axle spindles parallel to a straight axle then bends the axle tube to put camber in the spindle which in turn puts camber in wheel and tire. Makes sense to a point? Putting a certain degree of wheel camber in an uncertain amount of trailer weight on an axle leaves anyone guessing as to how much camber. Do you know how much degree of camber is designed into a 3500 lb axle 95” long? What spikes my curiosity is if trailer is empty and being pulled a long distance that would cause excessive tire wear on outside tread, but on the other hand if it’s loaded heavy how much camber would an engineer need to put in axle but not knowing the weight. Not wanting to be argumentative but I’m having this disagreement with a few people I would like to hear the opinion of an expert. Thankyou

The amount of bow that's put into trailer axles like the # 7359765 is based on about how much a trailer is typically going to weigh that has a 3,500 lb capacity. So there's a bit of approximation and obviously it can't be totally perfect for every weight but it's basically going to be "good enough" for that typical weight range put on a 3,500 lb trailer.
