Tire load numbers come from, wait for it, the tires :-)
My state (and every other one I have researched, maybe 5 or 6) only cares about registration and tire loading. Now that doesn't mean you couldn't get a ticket for loading a Ranger to capacity with a DRW conversion and LRH tires... it just would be for something different.
The only two places manufacturers axle weight rating are mentioned in Idaho is in the glossary and when talking about TAG axles. A TAG axle is the only axle that must be at/under the mfgr GAWR, otherwise game on (within reason).

I am 100% legal going down the road at 7300lbs on my rear axle with a door sticker of 6200 RAWR. I am registered for 26K GCW and have tires that allow for a RAW of 9K.
Your post above was not about where brake ratings come from it was where axle ratings come from.
GAWR tells you a minimum brake rating, but it doesn't tell you the actual brake rating (generally speaking). The front/rear differences I mentioned above with higher RAWR than front show that alone. My pickup is a great example. 5200/6200 or 5200/9350 when equipped as a DRW. The front brakes are larger than the rear brakes so we know the brakes on the front are helping stop the rear axle load. We know that based on the inverse axle rating to brake size and the percentage of braking that occurs by the front axle. Another example is trailer brakes. The brakes found on my 5200lb axles are the same brakes found on 6K, 7K, and some 8K axles.
There are also blurbs from Ford, (and I recall the other being Dodge but have had a hard time finding it) that state their brake ratings are around GVWR plus the 2,000lbs allowed for a trailer without brakes. But is that for cars? LD trucks? HD trucks?
Then again it is really here nor there as all this does is show most of us have a LOT more brake than rating, which is not a bad thing.
